-/**
- * Helper function to swap the text of a TranslationItem
- * between its original and translated states.
- * How it works:
- *
- * The function iterates through the target array (either the `original` or
- * `translation` array from the TranslationItem), while also keeping a pointer
- * to a current position in the child nodes from the actual DOM node that we
- * are modifying. This pointer is moved forward after each item of the array
- * is translated. If, at any given time, the pointer doesn't match the expected
- * node that was supposed to be seen, it means that the original and translated
- * contents have a different ordering, and thus we need to adjust that.
- *
- * A full example of the reordering process, swapping from Original to
- * Translation:
- *
- *    Original (en): <div>I <em>miss</em> <b>you</b></div>
- *
- * Translation (fr): <div><b>Tu</b> me <em>manques</em></div>
- *
- * Step 1:
- *   pointer points to firstChild of the DOM node, textnode "I "
- *   first item in item.translation is [object TranslationItem <b>]
- *
- *   pointer does not match the expected element, <b>. So let's move <b> to the
- *   pointer position.
- *
- *   Current state of the DOM:
- *     <div><b>you</b>I <em>miss</em> </div>
- *
- * Step 2:
- *   pointer moves forward to nextSibling, textnode "I " again.
- *   second item in item.translation is the string " me "
- *
- *   pointer points to a text node, and we were expecting a text node. Match!
- *   just replace the text content.
- *
- *   Current state of the DOM:
- *     <div><b>you</b> me <em>miss</em> </div>
- *
- * Step 3:
- *   pointer moves forward to nextSibling, <em>miss</em>
- *   third item in item.translation is [object TranslationItem <em>]
- *
- *   pointer points to the expected node. Match! Nothing to do.
- *
- * Step 4:
- *   all items in this item.translation were transformed. The remaining
- *   text nodes are cleared to "", and domNode.normalize() removes them.
- *
- *   Current state of the DOM:
- *     <div><b>you</b> me <em>miss</em></div>
- *
- * Further steps:
- *   After that, the function will visit the child items (from the visitStack),
- *   and the text inside the <b> and <em> nodes will be swapped as well,
- *   yielding the final result:
- *
- *     <div><b>Tu</b> me <em>manques</em></div>
- *
- *
- * @param item     A TranslationItem object
- * @param target   A string that is either "translation"
- *                 or "original".

-      // was broken in various chunks, and one of the chunks failed,
-      // the items from that chunk will be missing its "translation"
-      // field.

-    // modifying. During most of the process, while the target array is
-    // being iterated (in the for loop below), it should walk together with
-    // the array and be pointing to the correct node that needs to modified.
-    // If it's not pointing to it, that means some sort of node reordering
-    // will be necessary to produce the correct translation.
-    // Note that text nodes don't need to be reordered, as we can just replace
-    // the content of one text node with another.
-    //
-    // curNode starts in the firstChild...
-    let curNode = domNode.firstChild;
-
-    // ... actually, let's make curNode start at the first useful node (either
-    // a non-blank text node or something else). This is not strictly necessary,
-    // as the reordering algorithm would correctly handle this case. However,
-    // this better aligns the resulting translation with the DOM content of the
-    // page, avoiding cases that would need to be unecessarily reordered.
-    //
-    // An example of how this helps:
-    //
-    // ---- Original: <div>                <b>Hello </b> world.</div>
-    //                       ^textnode 1      ^item 1      ^textnode 2
-    //
-    // - Translation: <div><b>Hallo </b> Welt.</div>
-    //
-    // Transformation process without this optimization:
-    //   1 - start pointer at textnode 1
-    //   2 - move item 1 to first position inside the <div>
-    //
-    //       Node now looks like: <div><b>Hello </b>[         ][ world.]</div>
-    //                                         textnode 1^       ^textnode 2
-    //
-    //   3 - replace textnode 1 with " Welt."
-    //   4 - clear remaining text nodes (in this case, textnode 2)
-    //
-    // Transformation process with this optimization:
-    //   1 - start pointer at item 1
-    //   2 - item 1 is already in position
-    //   3 - replace textnode 2 with " Welt."
-    //
-    // which completely avoids any node reordering, and requires only one
-    // text change instead of two (while also leaving the page closer to
-    // its original state).

-
-# Do not replace $BrandShortName, $BrandFullName, or $BrandFullNameDA with a
-# custom string and always use the same one as used by the en-US files.
-# $BrandFullNameDA allows the string to contain an ampersand (e.g. DA stands
-# for double ampersand) and prevents the letter following the ampersand from

+/**
+ * Span - slices for C++
+ *
+ * Span implements Rust's slice concept for C++. It's called "Span" instead of
+ * "Slice" to follow the naming used in C++ Core Guidelines.
+ *
+ * A Span wraps a pointer and a length that identify a non-owning view to a
+ * contiguous block of memory of objects of the same type. Various types,
+ * including (pre-decay) C arrays, XPCOM strings, nsTArray, mozilla::Array,
+ * mozilla::Range and contiguous standard-library containers, auto-convert
+ * into Spans when attempting to pass them as arguments to methods that take
+ * Spans. MakeSpan() functions can be used for explicit conversion in other
+ * contexts. (Span itself autoconverts into mozilla::Range.)
+ *
+ * Like Rust's slices, Span provides safety against out-of-bounds access by
+ * performing run-time bound checks. However, unlike Rust's slices, Span
+ * cannot provide safety against use-after-free.
+ *
+ * (Note: Span is like Rust's slice only conceptually. Due to the lack of
+ * ABI guarantees, you should still decompose spans/slices to raw pointer
+ * and length parts when crossing the FFI.)
+ *
+ * In addition to having constructors and MakeSpan() functions that take
+ * various well-known types, a Span for an arbitrary type can be constructed
+ * (via constructor or MakeSpan()) from a pointer and a length or a pointer
+ * and another pointer pointing just past the last element.
+ *
+ * A Span<const char> can be obtained for const char* pointing to a
+ * zero-terminated C string using the MakeCStringSpan() function. A
+ * corresponding implicit constructor does not exist in order to avoid
+ * accidental construction in cases where const char* does not point to a
+ * zero-terminated C string.
+ *
+ * Span has methods that follow the Mozilla naming style and methods that
+ * don't. The methods that follow the Mozilla naming style are meant to be
+ * used directly from Mozilla code. The methods that don't are meant for
+ * integration with C++11 range-based loops and with meta-programming that
+ * expects the same methods that are found on the standard-library
+ * containers. For example, to decompose a Span into its parts in Mozilla
+ * code, use Elements() and Length() (as with nsTArray) instead of data()
+ * and size() (as with std::vector).
+ *
+ * The pointer and length wrapped by a Span cannot be changed after a Span has
+ * been created. When new values are required, simply create a new Span. Span
+ * has a method called Subspan() that works analogously to the Substring()
+ * method of XPCOM strings taking a start index and an optional length. As a
+ * Mozilla extension (relative to Microsoft's gsl::span that mozilla::Span is
+ * based on), Span has methods From(start), To(end) and FromTo(start, end)
+ * that correspond to Rust's &slice[start..], &slice[..end] and
+ * &slice[start..end], respectively. (That is, the end index is the index of
+ * the first element not to be included in the new subspan.)
+ *
+ * When indicating a Span that's only read from, const goes inside the type
+ * parameter. Don't put const in front of Span. That is:
+ * size_t ReadsFromOneSpanAndWritesToAnother(Span<const uint8_t> aReadFrom,
+ *                                           Span<uint8_t> aWrittenTo);
+ *
+ * Any Span<const T> can be viewed as Span<const uint8_t> using the function
+ * AsBytes(). Any Span<T> can be viewed as Span<uint8_t> using the function
+ * AsWritableBytes().

+## Building the library and applications
+
+### Prerequisites
+
+ 1. [CMake](https://cmake.org) version 3.5 or higher.
+ 2. [Git](https://git-scm.com/).
+ 3. [Perl](https://www.perl.org/).
+ 4. For x86 targets, [yasm](http://yasm.tortall.net/), which is preferred, or a
+    recent version of [nasm](http://www.nasm.us/).
+ 5. Building the documentation requires [doxygen](http://doxygen.org).
+ 6. Building the unit tests requires [Python](https://www.python.org/).
+ 7. Emscripten builds require the portable
+   [EMSDK](https://kripken.github.io/emscripten-site/index.html).
+
+### Get the code
+
+The AV1 library source code is stored in the Alliance for Open Media Git
+repository:
+
+~~~
+    $ git clone https://aomedia.googlesource.com/aom
+    # By default, the above command stores the source in the aom directory:
+    $ cd aom
+~~~
+
+### Basic build
+
+CMake replaces the configure step typical of many projects. Running CMake will
+produce configuration and build files for the currently selected CMake
+generator. For most systems the default generator is Unix Makefiles. The basic
+form of a makefile build is the following:
+
+~~~
+    $ cmake path/to/aom
+    $ make
+~~~
+
+The above will generate a makefile build that produces the AV1 library and
+applications for the current host system after the make step completes
+successfully. The compiler chosen varies by host platform, but a general rule
+applies: On systems where cc and c++ are present in $PATH at the time CMake is
+run the generated build will use cc and c++ by default.
+
+### Configuration options
+
+The AV1 codec library has a great many configuration options. These come in two
+varieties:
+
+ 1. Build system configuration options. These have the form `ENABLE_FEATURE`.
+ 2. AV1 codec configuration options. These have the form `CONFIG_FEATURE`.
+
+Both types of options are set at the time CMake is run. The following example
+enables ccache and disables the AV1 encoder:
+
+~~~
+    $ cmake path/to/aom -DENABLE_CCACHE=1 -DCONFIG_AV1_ENCODER=0
+    $ make
+~~~
+
+The available configuration options are too numerous to list here. Build system
+configuration options can be found at the top of the CMakeLists.txt file found
+in the root of the AV1 repository, and AV1 codec configuration options can
+currently be found in the file `build/cmake/aom_config_defaults.cmake`.
+
+### Dylib builds
+
+A dylib (shared object) build of the AV1 codec library can be enabled via the
+CMake built in variable `BUILD_SHARED_LIBS`:
+
+~~~
+    $ cmake path/to/aom -DBUILD_SHARED_LIBS=1
+    $ make
+~~~
+
+This is currently only supported on non-Windows targets.
+
+### Debugging
+
+Depending on the generator used there are multiple ways of going about
+debugging AV1 components. For single configuration generators like the Unix
+Makefiles generator, setting `CMAKE_BUILD_TYPE` to Debug is sufficient:
+
+~~~
+    $ cmake path/to/aom -DCMAKE_BUILD_TYPE=Debug
+~~~
+
+For Xcode, mainly because configuration controls for Xcode builds are buried two
+configuration windows deep and must be set for each subproject within the Xcode
+IDE individually, `CMAKE_CONFIGURATION_TYPES` should be set to Debug:
+
+~~~
+    $ cmake path/to/aom -G Xcode -DCMAKE_CONFIGURATION_TYPES=Debug
+~~~
+
+For Visual Studio the in-IDE configuration controls should be used. Simply set
+the IDE project configuration to Debug to allow for stepping through the code.
+
+In addition to the above it can sometimes be useful to debug only C and C++
+code. To disable all assembly code and intrinsics set `AOM_TARGET_CPU` to
+generic at generation time:
+
+~~~
+    $ cmake path/to/aom -DAOM_TARGET_CPU=generic
+~~~
+
+### Cross compiling
+
+For the purposes of building the AV1 codec and applications and relative to the
+scope of this guide, all builds for architectures differing from the native host
+architecture will be considered cross compiles. The AV1 CMake build handles
+cross compiling via the use of toolchain files included in the AV1 repository.
+The toolchain files available at the time of this writing are:
+
+ - arm64-ios.cmake
+ - arm64-linux-gcc.cmake
+ - arm64-mingw-gcc.cmake
+ - armv7-ios.cmake
+ - armv7-linux-gcc.cmake
+ - armv7-mingw-gcc.cmake
+ - armv7s-ios.cmake
+ - mips32-linux-gcc.cmake
+ - mips64-linux-gcc.cmake
+ - x86-ios-simulator.cmake
+ - x86-linux.cmake
+ - x86-macos.cmake
+ - x86-mingw-gcc.cmake
+ - x86\_64-ios-simulator.cmake
+ - x86\_64-mingw-gcc.cmake
+
+The following example demonstrates use of the x86-macos.cmake toolchain file on
+a x86\_64 MacOS host:
+
+~~~
+    $ cmake path/to/aom \
+      -DCMAKE_TOOLCHAIN_FILE=path/to/aom/build/cmake/toolchains/x86-macos.cmake
+    $ make
+~~~
+
+To build for an unlisted target creation of a new toolchain file is the best
+solution. The existing toolchain files can be used a starting point for a new
+toolchain file since each one exposes the basic requirements for toolchain files
+as used in the AV1 codec build.
+
+As a temporary work around an unoptimized AV1 configuration that builds only C
+and C++ sources can be produced using the following commands:
+
+~~~
+    $ cmake path/to/aom -DAOM_TARGET_CPU=generic
+    $ make
+~~~
+
+In addition to the above it's important to note that the toolchain files
+suffixed with gcc behave differently than the others. These toolchain files
+attempt to obey the $CROSS environment variable.
+
+### Sanitizers
+
+Sanitizer integration is built-in to the CMake build system. To enable a
+sanitizer, add `-DSANITIZE=<type>` to the CMake command line. For example, to
+enable address sanitizer:
+
+~~~
+    $ cmake path/to/aom -DSANITIZE=address
+    $ make
+~~~
+
+Sanitizers available vary by platform, target, and compiler. Consult your
+compiler documentation to determine which, if any, are available.
+
+### Microsoft Visual Studio builds
+
+Building the AV1 codec library in Microsoft Visual Studio is supported. The
+following example demonstrates generating projects and a solution for the
+Microsoft IDE:
+
+~~~
+    # This does not require a bash shell; command.exe is fine.
+    $ cmake path/to/aom -G "Visual Studio 15 2017"
+~~~
+
+### Xcode builds
+
+Building the AV1 codec library in Xcode is supported. The following example
+demonstrates generating an Xcode project:
+
+~~~
+    $ cmake path/to/aom -G Xcode
+~~~
+
+### Emscripten builds
+
+Building the AV1 codec library with Emscripten is supported. Typically this is
+used to hook into the AOMAnalyzer GUI application. These instructions focus on
+using the inspector with AOMAnalyzer, but all tools can be built with
+Emscripten.
+
+It is assumed here that you have already downloaded and installed the EMSDK,
+installed and activated at least one toolchain, and setup your environment
+appropriately using the emsdk\_env script.
+
+1. Download [AOMAnalyzer](https://people.xiph.org/~mbebenita/analyzer/).
+
+2. Configure the build:
+
+~~~
+    $ cmake path/to/aom \
+        -DENABLE_CCACHE=1 \
+        -DAOM_TARGET_CPU=generic \
+        -DENABLE_DOCS=0 \
+        -DENABLE_TESTS=0 \
+        -DCONFIG_ACCOUNTING=1 \
+        -DCONFIG_INSPECTION=1 \
+        -DCONFIG_MULTITHREAD=0 \
+        -DCONFIG_RUNTIME_CPU_DETECT=0 \
+        -DCONFIG_WEBM_IO=0 \
+        -DCMAKE_TOOLCHAIN_FILE=path/to/emsdk-portable/.../Emscripten.cmake
+~~~
+
+3. Build it: run make if that's your generator of choice:
+
+~~~
+    $ make inspect
+~~~
+
+4. Run the analyzer:
+
+~~~
+    # inspect.js is in the examples sub directory of the directory in which you
+    # executed cmake.
+    $ path/to/AOMAnalyzer path/to/examples/inspect.js path/to/av1/input/file
+~~~
+
+### Extra build flags
+
+Three variables allow for passing of additional flags to the build system.
+
+- AOM\_EXTRA\_C\_FLAGS
+- AOM\_EXTRA\_CXX\_FLAGS
+- AOM\_EXTRA\_EXE\_LINKER\_FLAGS
+
+The build system attempts to ensure the flags passed through the above variables
+are passed to tools last in order to allow for override of default behavior.
+These flags can be used, for example, to enable asserts in a release build:
+
+~~~
+    $ cmake path/to/aom \
+        -DCMAKE_BUILD_TYPE=Release \
+        -DAOM_EXTRA_C_FLAGS=-UNDEBUG \
+        -DAOM_EXTRA_CXX_FLAGS=-UNDEBUG
+~~~
+
+## Testing the AV1 codec
+
+### Testing basics
+
+There are several methods of testing the AV1 codec. All of these methods require
+the presence of the AV1 source code and a working build of the AV1 library and
+applications.
+
+#### 1. Unit tests:
+
+The unit tests can be run at build time:
+
+~~~
+    # Before running the make command the LIBAOM_TEST_DATA_PATH environment
+    # variable should be set to avoid downloading the test files to the
+    # cmake build configuration directory.
+    $ cmake path/to/aom
+    # Note: The AV1 CMake build creates many test targets. Running make
+    # with multiple jobs will speed up the test run significantly.
+    $ make runtests
+~~~
+
+#### 2. Example tests:
+
+The example tests require a bash shell and can be run in the following manner:
+
+~~~
+    # See the note above about LIBAOM_TEST_DATA_PATH above.
+    $ cmake path/to/aom
+    $ make
+    # It's best to build the testdata target using many make jobs.
+    # Running it like this will verify and download (if necessary)
+    # one at a time, which takes a while.
+    $ make testdata
+    $ path/to/aom/test/examples.sh --bin-path examples
+~~~
+
+#### 3. Encoder tests:
+
+When making a change to the encoder run encoder tests to confirm that your
+change has a positive or negligible impact on encode quality. When running these
+tests the build configuration should be changed to enable internal encoder
+statistics:
+
+~~~
+    $ cmake path/to/aom -DCONFIG_INTERNAL_STATS=1
+    $ make
+~~~
+
+The repository contains scripts intended to make running these tests as simple
+as possible. The following example demonstrates creating a set of baseline clips
+for comparison to results produced after making your change to libaom:
+
+~~~
+    # This will encode all Y4M files in the current directory using the
+    # settings specified to create the encoder baseline statistical data:
+    $ cd path/to/test/inputs
+    # This command line assumes that run_encodes.sh, its helper script
+    # best_encode.sh, and the aomenc you intend to test are all within a
+    # directory in your PATH.
+    $ run_encodes.sh 200 500 50 baseline
+~~~
+
+After making your change and creating the baseline clips, you'll need to run
+encodes that include your change(s) to confirm that things are working as
+intended:
+
+~~~
+    # This will encode all Y4M files in the current directory using the
+    # settings specified to create the statistical data for your change:
+    $ cd path/to/test/inputs
+    # This command line assumes that run_encodes.sh, its helper script
+    # best_encode.sh, and the aomenc you intend to test are all within a
+    # directory in your PATH.
+    $ run_encodes.sh 200 500 50 mytweak
+~~~
+
+After creating both data sets you can use `test/visual_metrics.py` to generate a
+report that can be viewed in a web browser:
+
+~~~
+    $ visual_metrics.py metrics_template.html "*stt" baseline mytweak \
+      > mytweak.html
+~~~
+
+You can view the report by opening mytweak.html in a web browser.
+
+
+### IDE hosted tests
+
+By default the generated projects files created by CMake will not include the
+runtests and testdata rules when generating for IDEs like Microsoft Visual
+Studio and Xcode. This is done to avoid intolerably long build cycles in the
+IDEs-- IDE behavior is to build all targets when selecting the build project
+options in MSVS and Xcode. To enable the test rules in IDEs the
+`ENABLE_IDE_TEST_HOSTING` variable must be enabled at CMake generation time:
+
+~~~
+    # This example uses Xcode. To get a list of the generators
+    # available, run cmake with the -G argument missing its
+    # value.
+    $ cmake path/to/aom -DENABLE_IDE_TEST_HOSTING=1 -G Xcode
+~~~
+
+### Downloading the test data
+
+The fastest and easiest way to obtain the test data is to use CMake to generate
+a build using the Unix Makefiles generator, and then to build only the testdata
+rule:
+
+~~~
+    $ cmake path/to/aom -G "Unix Makefiles"
+    # 28 is used because there are 28 test files as of this writing.
+    $ make -j28 testdata
+~~~
+
+The above make command will only download and verify the test data.
+
+### Adding a new test data file
+
+First, add the new test data file to the `aom-test-data` bucket of the
+`aomedia-testing` project on Google Cloud Platform. You may need to ask someone
+with the necessary access permissions to do this for you.
+
+NOTE: When a new test data file is added to the `aom-test-data` bucket, its
+"Public access" is initially "Not public". We need to change its
+"Public access" to "Public" by using the following
+[`gsutil`](https://cloud.google.com/storage/docs/gsutil_install) command:
+~~~
+    $ gsutil acl ch -g all:R gs://aom-test-data/test-data-file-name
+~~~
+This command grants the `AllUsers` group READ access to the file named
+"test-data-file-name" in the `aom-test-data` bucket.
+
+Once the new test data file has been added to `aom-test-data`, create a CL to
+add the name of the new test data file to `test/test_data_util.cmake` and add
+the SHA1 checksum of the new test data file to `test/test-data.sha1`. (The SHA1
+checksum of a file can be calculated by running the `sha1sum` command on the
+file.)
+
+### Additional test data
+
+The test data mentioned above is strictly intended for unit testing.
+
+Additional input data for testing the encoder can be obtained from:
+https://media.xiph.org/video/derf/
+
+### Sharded testing
+
+The AV1 codec library unit tests are built upon gtest which supports sharding of
+test jobs. Sharded test runs can be achieved in a couple of ways.
+
+#### 1. Running test\_libaom directly:
+
+~~~
+   # Set the environment variable GTEST_TOTAL_SHARDS to control the number of
+   # shards.
+   $ export GTEST_TOTAL_SHARDS=10
+   # (GTEST shard indexing is 0 based).
+   $ seq 0 $(( $GTEST_TOTAL_SHARDS - 1 )) \
+       | xargs -n 1 -P 0 -I{} env GTEST_SHARD_INDEX={} ./test_libaom
+~~~
+
+To create a test shard for each CPU core available on the current system set
+`GTEST_TOTAL_SHARDS` to the number of CPU cores on your system minus one.
+
+#### 2. Running the tests via the CMake build:
+
+~~~
+    # For IDE based builds, ENABLE_IDE_TEST_HOSTING must be enabled. See
+    # the IDE hosted tests section above for more information. If the IDE
+    # supports building targets concurrently tests will be sharded by default.
+
+    # For make and ninja builds the -j parameter controls the number of shards
+    # at test run time. This example will run the tests using 10 shards via
+    # make.
+    $ make -j10 runtests
+~~~
+
+The maximum number of test targets that can run concurrently is determined by
+the number of CPUs on the system where the build is configured as detected by
+CMake. A system with 24 cores can run 24 test shards using a value of 24 with
+the `-j` parameter. When CMake is unable to detect the number of cores 10 shards
+is the default maximum value.
+
+## Coding style
+
+We are using the Google C Coding Style defined by the
+[Google C++ Style Guide](https://google.github.io/styleguide/cppguide.html).
+
+The coding style used by this project is enforced with clang-format using the
+configuration contained in the
+[.clang-format](https://chromium.googlesource.com/webm/aom/+/master/.clang-format)
+file in the root of the repository.
+
+You can download clang-format using your system's package manager, or directly
+from [llvm.org](http://llvm.org/releases/download.html). You can also view the
+[documentation](https://clang.llvm.org/docs/ClangFormat.html) on llvm.org.
+Output from clang-format varies by clang-format version, for best results your
+version should match the one used on Jenkins. You can find the clang-format
+version by reading the comment in the `.clang-format` file linked above.
+
+Before pushing changes for review you can format your code with:
+
+~~~
+    # Apply clang-format to modified .c, .h and .cc files
+    $ clang-format -i --style=file \
+      $(git diff --name-only --diff-filter=ACMR '*.[hc]' '*.cc')
+~~~
+
+Check the .clang-format file for the version used to generate it if there is any
+difference between your local formatting and the review system.
+
+Some Git installations have clang-format integration. Here are some examples:
+
+~~~
+    # Apply clang-format to all staged changes:
+    $ git clang-format
+
+    # Clang format all staged and unstaged changes:
+    $ git clang-format -f
+
+    # Clang format all staged and unstaged changes interactively:
+    $ git clang-format -f -p
+~~~
+
+## Submitting patches
+
+We manage the submission of patches using the
+[Gerrit](https://www.gerritcodereview.com/) code review tool. This tool
+implements a workflow on top of the Git version control system to ensure that
+all changes get peer reviewed and tested prior to their distribution.
+
+### Login cookie
+
+Browse to [AOMedia Git index](https://aomedia.googlesource.com/) and login with
+your account (Gmail credentials, for example). Next, follow the
+`Generate Password` Password link at the top of the page. You’ll be given
+instructions for creating a cookie to use with our Git repos.
+
+### Contributor agreement
+
+You will be required to execute a
+[contributor agreement](http://aomedia.org/license) to ensure that the AOMedia
+Project has the right to distribute your changes.
+
+### Testing your code
+
+The testing basics are covered in the [testing section](#testing-the-av1-codec)
+above.
+
+In addition to the local tests, many more (e.g. asan, tsan, valgrind) will run
+through Jenkins instances upon upload to gerrit.
+
+### Commit message hook
+
+Gerrit requires that each submission include a unique Change-Id. You can assign
+one manually using git commit --amend, but it’s easier to automate it with the
+commit-msg hook provided by Gerrit.
+
+Copy commit-msg to the `.git/hooks` directory of your local repo. Here's an
+example:
+
+~~~
+    $ curl -Lo aom/.git/hooks/commit-msg https://chromium-review.googlesource.com/tools/hooks/commit-msg
+
+    # Next, ensure that the downloaded commit-msg script is executable:
+    $ chmod u+x aom/.git/hooks/commit-msg
+~~~
+
+See the Gerrit
+[documentation](https://gerrit-review.googlesource.com/Documentation/user-changeid.html)
+for more information.
+
+### Upload your change
+
+The command line to upload your patch looks like this:
+
+~~~
+    $ git push https://aomedia-review.googlesource.com/aom HEAD:refs/for/master
+~~~
+
+### Incorporating reviewer comments
+
+If you previously uploaded a change to Gerrit and the Approver has asked for
+changes, follow these steps:
+
+1. Edit the files to make the changes the reviewer has requested.
+2. Recommit your edits using the --amend flag, for example:
+
+~~~
+   $ git commit -a --amend
+~~~
+
+3. Use the same git push command as above to upload to Gerrit again for another
+   review cycle.
+
+In general, you should not rebase your changes when doing updates in response to
+review. Doing so can make it harder to follow the evolution of your change in
+the diff view.
+
+### Submitting your change
+
+Once your change has been Approved and Verified, you can “submit” it through the
+Gerrit UI. This will usually automatically rebase your change onto the branch
+specified.
+
+Sometimes this can’t be done automatically. If you run into this problem, you
+must rebase your changes manually:
+
+~~~
+    $ git fetch
+    $ git rebase origin/branchname
+~~~
+
+If there are any conflicts, resolve them as you normally would with Git. When
+you’re done, reupload your change.
+
+### Viewing the status of uploaded changes
+
+To check the status of a change that you uploaded, open
+[Gerrit](https://aomedia-review.googlesource.com/), sign in, and click My >
+Changes.

+ * \brief Describes the decoder algorithm interface for algorithm
+ *        implementations.
+ *
+ * This file defines the private structures and data types that are only
+ * relevant to implementing an algorithm, as opposed to using it.
+ *
+ * To create a decoder algorithm class, an interface structure is put
+ * into the global namespace:
+ *     <pre>
+ *     my_codec.c:
+ *       aom_codec_iface_t my_codec = {
+ *           "My Codec v1.0",
+ *           AOM_CODEC_ALG_ABI_VERSION,
+ *           ...
+ *       };
+ *     </pre>
+ *
+ * An application instantiates a specific decoder instance by using
+ * aom_codec_init() and a pointer to the algorithm's interface structure:
+ *     <pre>
+ *     my_app.c:
+ *       extern aom_codec_iface_t my_codec;
+ *       {
+ *           aom_codec_ctx_t algo;
+ *           res = aom_codec_init(&algo, &my_codec);
+ *       }
+ *     </pre>
+ *
+ * Once initialized, the instance is managed using other functions from
+ * the aom_codec_* family.

+/*A range decoder.
+  This is an entropy decoder based upon \cite{Mar79}, which is itself a
+   rediscovery of the FIFO arithmetic code introduced by \cite{Pas76}.
+  It is very similar to arithmetic encoding, except that encoding is done with
+   digits in any base, instead of with bits, and so it is faster when using
+   larger bases (i.e.: a byte).
+  The author claims an average waste of $\frac{1}{2}\log_b(2b)$ bits, where $b$
+   is the base, longer than the theoretical optimum, but to my knowledge there
+   is no published justification for this claim.
+  This only seems true when using near-infinite precision arithmetic so that
+   the process is carried out with no rounding errors.
+
+  An excellent description of implementation details is available at
+   http://www.arturocampos.com/ac_range.html
+  A recent work \cite{MNW98} which proposes several changes to arithmetic
+   encoding for efficiency actually re-discovers many of the principles
+   behind range encoding, and presents a good theoretical analysis of them.
+
+  End of stream is handled by writing out the smallest number of bits that
+   ensures that the stream will be correctly decoded regardless of the value of
+   any subsequent bits.
+  od_ec_dec_tell() can be used to determine how many bits were needed to decode
+   all the symbols thus far; other data can be packed in the remaining bits of
+   the input buffer.

+/*!\brief A function pointer for computing 1d fft and ifft.
+ *
+ * The function will point to an implementation for a specific transform size,
+ * and may perform the transforms using vectorized instructions.
+ *
+ * For a non-vectorized forward transforms of size n, the input and output
+ * buffers will be size n. The output takes advantage of conjugate symmetry and
+ * packs the results as: [r_0, r_1, ..., r_{n/2}, i_1, ..., i_{n/2-1}], where
+ * (r_{j}, i_{j}) is the complex output for index j.
+ *
+ * An inverse transform will assume that the complex "input" is packed
+ * similarly. Its output will be real.
+ *
+ * Non-vectorized transforms (e.g., on a single row) would use a stride = 1.
+ *
+ * Vectorized implementations are parallelized along the columns so that the fft
+ * can be performed on multiple columns at a time. In such cases the data block
+ * for input and output is typically square (n x n) and the stride will
+ * correspond to the spacing between rows. At minimum, the input size must be
+ * n x simd_vector_length.
+ *
+ * \param[in]  input   Input buffer. See above for size restrictions.

+ * \brief A table mapping from time to corresponding film grain parameters.
+ *
+ * In order to apply grain synthesis in the decoder, the film grain parameters
+ * need to be signalled in the encoder. The film grain parameters are time
+ * varying, and for two-pass encoding (and denoiser implementation flexibility)
+ * it is common to denoise the video and do parameter estimation before encoding
+ * the denoised video.
+ *
+ * The film grain table is used to provide this flexibility and is used as a
+ * parameter that is passed to the encoder.
+ *
+ * Further, if regraining is to be done in say a single pass mode, or in two
+ * pass within the encoder (before frames are added to the lookahead buffer),
+ * this data structure can be used to keep track of on-the-fly estimated grain
+ * parameters, that are then extracted from the table before the encoded frame
+ * is written.

+ * This function provides portable primitives for getting and setting of
+ * signed and unsigned integers in 16, 24, and 32 bit sizes. The operations
+ * can be performed on unaligned data regardless of hardware support for
+ * unaligned accesses.
+ *
+ * The type used to pass the integral values may be changed by defining
+ * MEM_VALUE_T with the appropriate type. The type given must be an integral
+ * numeric type.
+ *
+ * The actual functions instantiated have the MEM_VALUE_T type name pasted
+ * on to the symbol name. This allows the developer to instantiate these
+ * operations for multiple types within the same translation unit. This is
+ * of somewhat questionable utility, but the capability exists nonetheless.
+ * Users not making use of this functionality should call the functions
+ * without the type name appended, and the preprocessor will take care of
+ * it.
+ *
+ * NOTE: This code is not supported on platforms where char > 1 octet ATM.

+   * Each coefficient is stored in 8 bits instead of 16 bits
+   * The coefficients are rearranged in the column order 0, 2, 4, 6, 1, 3, 5, 7
+
+     This is done in order to avoid overflow: Since the tap with the largest
+     coefficient could be any of taps 2, 3, 4 or 5, we can't use the summation
+     order ((0 + 1) + (4 + 5)) + ((2 + 3) + (6 + 7)) used in the regular
+     convolve functions.
+
+     Instead, we use the summation order
+     ((0 + 2) + (4 + 6)) + ((1 + 3) + (5 + 7)).
+     The rearrangement of coefficients in this table is so that we can get the
+     coefficients into the correct order more quickly.

+// the transform stages scale the coefficient values up by a factor of
+// 8 (3 bits) over the scale of the pixel values.  Thus, for 8-bit
+// input, the coefficients have effectively 11 bits of scale depth
+// (8+3), 10-bit input pixels result in 13-bit coefficient depth
+// (10+3) and 12-bit pixels yield 15-bit (12+3) coefficient depth.
+// All quantizers are built using this invariant of x8, 3-bit scaling,
+// thus the Q3 suffix.
+
+// A partial exception to this rule is large transforms; to avoid
+// overflow, TX blocks with > 256 pels (>16x16) are scaled only
+// 4-times unity (2 bits) over the pixel depth, and TX blocks with
+// over 1024 pixels (>32x32) are scaled up only 2x unity (1 bit).
+// This descaling is found via av1_tx_get_scale().  Thus, 16x32, 32x16
+// and 32x32 transforms actually return Q2 coefficients, and 32x64,
+// 64x32 and 64x64 transforms return Q1 coefficients.  However, the
+// quantizers are de-scaled down on-the-fly by the same amount
+// (av1_tx_get_scale()) during quantization, and as such the
+// dequantized/decoded coefficients, even for large TX blocks, are always
+// effectively Q3. Meanwhile, quantized/coded coefficients are Q0
+// because Qn quantizers are applied to Qn tx coefficients.
+
+// Note that encoder decision making (which uses the quantizer to
+// generate several bespoke lamdas for RDO and other heuristics)
+// expects quantizers to be larger for higher-bitdepth input.  In
+// addition, the minimum allowable quantizer is 4; smaller values will
+// underflow to 0 in the actual quantization routines.

+//   In this case, we use the 3 rows of CDEF output across the boundary for
+//   context; this corresponds to leaving the frame buffer as-is.
+//
+// * If we're at a tile boundary and loop filtering across tiles is disabled,
+//   then we take the outermost row of CDEF pixels *within the current tile*
+//   and copy it three times. Thus we behave exactly as if the tile were a full
+//   frame.
+//
+// * Otherwise, we're at a stripe boundary within a tile. In that case, we
+//   take 2 rows of deblocked pixels and extend them to 3 rows of context.

+/* The warp filter for ROTZOOM and AFFINE models works as follows:
+   * Split the input into 8x8 blocks
+   * For each block, project the point (4, 4) within the block, to get the
+     overall block position. Split into integer and fractional coordinates,
+     maintaining full WARPEDMODEL precision
+   * Filter horizontally: Generate 15 rows of 8 pixels each. Each pixel gets a
+     variable horizontal offset. This means that, while the rows of the
+     intermediate buffer align with the rows of the *reference* image, the
+     columns align with the columns of the *destination* image.
+   * Filter vertically: Generate the output block (up to 8x8 pixels, but if the
+     destination is too small we crop the output at this stage). Each pixel has
+     a variable vertical offset, so that the resulting rows are aligned with
+     the rows of the destination image.
+
+   To accomplish these alignments, we factor the warp matrix as a
+   product of two shear / asymmetric zoom matrices:
+   / a b \  = /   1       0    \ * / 1+alpha  beta \
+   \ c d /    \ gamma  1+delta /   \    0      1   /
+   where a, b, c, d are wmmat[2], wmmat[3], wmmat[4], wmmat[5] respectively.
+   The horizontal shear (with alpha and beta) is applied first,
+   then the vertical shear (with gamma and delta) is applied second.
+
+   The only limitation is that, to fit this in a fixed 8-tap filter size,
+   the fractional pixel offsets must be at most +-1. Since the horizontal filter
+   generates 15 rows of 8 columns, and the initial point we project is at (4, 4)
+   within the block, the parameters must satisfy
+   4 * |alpha| + 7 * |beta| <= 1   and   4 * |gamma| + 4 * |delta| <= 1
+   for this filter to be applicable.
+
+   Note: This function assumes that the caller has done all of the relevant
+   checks, ie. that we have a ROTZOOM or AFFINE model, that wm[4] and wm[5]
+   are set appropriately (if using a ROTZOOM model), and that alpha, beta,
+   gamma, delta are all in range.

+/* A note on hardware implementation:
+    The warp filter is intended to be implementable using the same hardware as
+    the high-precision convolve filters from the loop-restoration and
+    convolve-round experiments.
+
+    For a single filter stage, considering all of the coefficient sets for the
+    warp filter and the regular convolution filter, an input in the range
+    [0, 2^k - 1] is mapped into the range [-56 * (2^k - 1), 184 * (2^k - 1)]
+    before rounding.
+
+    Allowing for some changes to the filter coefficient sets, call the range
+    [-64 * 2^k, 192 * 2^k]. Then, if we initialize the accumulator to 64 * 2^k,
+    we can replace this by the range [0, 256 * 2^k], which can be stored in an
+    unsigned value with 8 + k bits.
+
+    This allows the derivation of the appropriate bit widths and offsets for
+    the various intermediate values: If
+
+    F := FILTER_BITS = 7 (or else the above ranges need adjusting)
+         So a *single* filter stage maps a k-bit input to a (k + F + 1)-bit
+         intermediate value.
+    H := ROUND0_BITS
+    V := VERSHEAR_REDUCE_PREC_BITS
+    (and note that we must have H + V = 2*F for the output to have the same
+     scale as the input)
+
+    then we end up with the following offsets and ranges:
+    Horizontal filter: Apply an offset of 1 << (bd + F - 1), sum fits into a
+                       uint{bd + F + 1}
+    After rounding: The values stored in 'tmp' fit into a uint{bd + F + 1 - H}.
+    Vertical filter: Apply an offset of 1 << (bd + 2*F - H), sum fits into a
+                     uint{bd + 2*F + 2 - H}
+    After rounding: The final value, before undoing the offset, fits into a
+                    uint{bd + 2}.
+
+    Then we need to undo the offsets before clamping to a pixel. Note that,
+    if we do this at the end, the amount to subtract is actually independent
+    of H and V:
+
+    offset to subtract = (1 << ((bd + F - 1) - H + F - V)) +
+                         (1 << ((bd + 2*F - H) - V))
+                      == (1 << (bd - 1)) + (1 << bd)
+
+    This allows us to entirely avoid clamping in both the warp filter and
+    the convolve-round experiment. As of the time of writing, the Wiener filter
+    from loop-restoration can encode a central coefficient up to 216, which
+    leads to a maximum value of about 282 * 2^k after applying the offset.
+    So in that case we still need to clamp.

+// AV1 Set Reference Frame
+// ============================
+//
+// This is an example demonstrating how to overwrite the AV1 encoder's
+// internal reference frame. In the sample we set the last frame to the
+// current frame. This technique could be used to bounce between two cameras.
+//
+// The decoder would also have to set the reference frame to the same value
+// on the same frame, or the video will become corrupt. The 'test_decode'
+// variable is set to 1 in this example that tests if the encoder and decoder
+// results are matching.
+//
+// Usage
+// -----
+// This example encodes a raw video. And the last argument passed in specifies
+// the frame number to update the reference frame on. For example, run
+// examples/aom_cx_set_ref av1 352 288 in.yuv out.ivf 4 30
+// The parameter is parsed as follows:
+//
+//
+// Extra Variables
+// ---------------
+// This example maintains the frame number passed on the command line
+// in the `update_frame_num` variable.
+//
+//
+// Configuration
+// -------------
+//
+// The reference frame is updated on the frame specified on the command
+// line.
+//
+// Observing The Effects
+// ---------------------
+// The encoder and decoder results should be matching when the same reference
+// frame setting operation is done in both encoder and decoder. Otherwise,
+// the encoder/decoder mismatch would be seen.

+// Decode With Drops Example
+// =========================
+//
+// This is an example utility which drops a series of frames, as specified
+// on the command line. This is useful for observing the error recovery
+// features of the codec.
+//
+// Usage
+// -----
+// This example adds a single argument to the `simple_decoder` example,
+// which specifies the range or pattern of frames to drop. The parameter is
+// parsed as follows:
+//
+// Dropping A Range Of Frames
+// --------------------------
+// To drop a range of frames, specify the starting frame and the ending
+// frame to drop, separated by a dash. The following command will drop
+// frames 5 through 10 (base 1).
+//
+//  $ ./decode_with_drops in.ivf out.i420 5-10
+//
+//
+// Dropping A Pattern Of Frames
+// ----------------------------
+// To drop a pattern of frames, specify the number of frames to drop and
+// the number of frames after which to repeat the pattern, separated by
+// a forward-slash. The following command will drop 3 of 7 frames.
+// Specifically, it will decode 4 frames, then drop 3 frames, and then
+// repeat.
+//
+//  $ ./decode_with_drops in.ivf out.i420 3/7
+//
+//
+// Extra Variables
+// ---------------
+// This example maintains the pattern passed on the command line in the
+// `n`, `m`, and `is_range` variables:
+//
+//
+// Making The Drop Decision
+// ------------------------
+// The example decides whether to drop the frame based on the current
+// frame number, immediately before decoding the frame.

+// Lightfield Bitstream Parsing
+// ============================
+//
+// This is a lightfield bitstream parsing example. It takes an input file
+// containing the whole compressed lightfield bitstream(ivf file), and parses it
+// and constructs and outputs a new bitstream that can be decoded by an AV1
+// decoder. The output bitstream contains reference frames(i.e. anchor frames),
+// camera frame header, and tile list OBUs. num_references is the number of
+// anchor frames coded at the beginning of the light field file.
+// After running the lightfield encoder, run lightfield bitstream parsing:
+// examples/lightfield_bitstream_parsing vase10x10.ivf vase_tile_list.ivf 4

+// Lightfield Encoder
+// ==================
+//
+// This is an example of a simple lightfield encoder.  It builds upon the
+// twopass_encoder.c example. It takes an input file in YV12 format,
+// treating it as a planar lightfield instead of a video. The img_width
+// and img_height arguments are the dimensions of the lightfield images,
+// while the lf_width and lf_height arguments are the number of
+// lightfield images in each dimension. The lf_blocksize determines the
+// number of reference images used for MCP. For example, 5 means that there
+// is a reference image for every 5x5 lightfield image block. All images
+// within a block will use the center image in that block as the reference
+// image for MCP.
+// Run "make test" to download lightfield test data: vase10x10.yuv.
+// Run lightfield encoder to encode whole lightfield:
+// examples/lightfield_encoder 1024 1024 vase10x10.yuv vase10x10.ivf 10 10 5
+
+// Note: In bitstream.c and encoder.c, define EXT_TILE_DEBUG as 1 will print
+// out the uncompressed header and the frame contexts, which can be used to
+// test the bit exactness of the headers and the frame contexts for large scale
+// tile coded frames.

+// Lightfield Tile List Decoder
+// ============================
+//
+// This is a lightfield tile list decoder example. It takes an input file that
+// contains the anchor frames that are references of the coded tiles, the camera
+// frame header, and tile list OBUs that include the tile information and the
+// compressed tile data. This input file is reconstructed from the encoded
+// lightfield ivf file, and is decodable by AV1 decoder. num_references is
+// the number of anchor frames coded at the beginning of the light field file.
+// num_tile_lists is the number of tile lists need to be decoded.
+// Run lightfield tile list decoder to decode an AV1 tile list file:
+// examples/lightfield_tile_list_decoder vase_tile_list.ivf vase_tile_list.yuv

+/*!\file
+ * \brief This is an sample binary to create noise params from input video.
+ *
+ * To allow for external denoising applications, this sample binary illustrates
+ * how to create a film grain table (film grain params as a function of time)
+ * from an input video and its corresponding denoised source.
+ *
+ * The --output-grain-table file can be passed as input to the encoder (in
+ * aomenc this is done through the "--film-grain-table" parameter).
+ *
+ * As an example, where the input source is an 854x480 yuv420p 8-bit video
+ * named "input.854_480.yuv" you would use steps similar to the following:
+ *
+ * # Run your denoiser (e.g, using hqdn3d filter):
+ * ffmpeg -vcodec rawvideo -video_size 854x480 -i input.854_480.yuv \
+ *    -vf hqdn3d=5:5:5:5 -vcodec rawvideo -an -f rawvideo \
+ *    denoised.854_480.yuv
+ *
+ * # Model the noise between the denoised version and original source:
+ * ./examples/noise_model --fps=25/1 --width=854 --height=480 --i420 \
+ *    --input-denoised=denoised.854_480.yuv --input=original.854_480.yuv \
+ *    --output-grain-table=film_grain.tbl
+ *
+ * # Encode with your favorite settings (including the grain table):
+ * aomenc --limit=100  --cpu-used=4 --input-bit-depth=8                  \
+ *    --i420 -w 854 -h 480 --end-usage=q --cq-level=25 --lag-in-frames=25 \
+ *    --auto-alt-ref=2 --bit-depth=8 --film-grain-table=film_grain.tbl \
+ *    -o denoised_with_grain_params.ivf denoised.854_480.yuv

+// Scalable Decoder
+// ==============
+//
+// This is an example of a scalable decoder loop. It takes a 2-spatial-layer
+// input file
+// containing the compressed data (in OBU format), passes it through the
+// decoder, and writes the decompressed frames to disk. The base layer and
+// enhancement layers are stored as separate files, out_lyr0.yuv and
+// out_lyr1.yuv, respectively.
+//
+// Standard Includes
+// -----------------
+// For decoders, you only have to include `aom_decoder.h` and then any
+// header files for the specific codecs you use. In this case, we're using
+// av1.
+//
+// Initializing The Codec
+// ----------------------
+// The libaom decoder is initialized by the call to aom_codec_dec_init().
+// Determining the codec interface to use is handled by AvxVideoReader and the
+// functions prefixed with aom_video_reader_. Discussion of those functions is
+// beyond the scope of this example, but the main gist is to open the input file
+// and parse just enough of it to determine if it's a AVx file and which AVx
+// codec is contained within the file.
+// Note the NULL pointer passed to aom_codec_dec_init(). We do that in this
+// example because we want the algorithm to determine the stream configuration
+// (width/height) and allocate memory automatically.
+//
+// Decoding A Frame
+// ----------------
+// Once the frame has been read into memory, it is decoded using the
+// `aom_codec_decode` function. The call takes a pointer to the data
+// (`frame`) and the length of the data (`frame_size`). No application data
+// is associated with the frame in this example, so the `user_priv`
+// parameter is NULL. The `deadline` parameter is left at zero for this
+// example. This parameter is generally only used when doing adaptive post
+// processing.
+//
+// Codecs may produce a variable number of output frames for every call to
+// `aom_codec_decode`. These frames are retrieved by the
+// `aom_codec_get_frame` iterator function. The iterator variable `iter` is
+// initialized to NULL each time `aom_codec_decode` is called.
+// `aom_codec_get_frame` is called in a loop, returning a pointer to a
+// decoded image or NULL to indicate the end of list.
+//
+// Processing The Decoded Data
+// ---------------------------
+// In this example, we simply write the encoded data to disk. It is
+// important to honor the image's `stride` values.
+//
+// Cleanup
+// -------
+// The `aom_codec_destroy` call frees any memory allocated by the codec.
+//
+// Error Handling
+// --------------
+// This example does not special case any error return codes. If there was
+// an error, a descriptive message is printed and the program exits. With
+// few exceptions, aom_codec functions return an enumerated error status,
+// with the value `0` indicating success.

+// Scalable Encoder
+// ==============
+//
+// This is an example of a scalable encoder loop. It takes two input files in
+// YV12 format, passes it through the encoder, and writes the compressed
+// frames to disk in OBU format.
+//
+// Getting The Default Configuration
+// ---------------------------------
+// Encoders have the notion of "usage profiles." For example, an encoder
+// may want to publish default configurations for both a video
+// conferencing application and a best quality offline encoder. These
+// obviously have very different default settings. Consult the
+// documentation for your codec to see if it provides any default
+// configurations. All codecs provide a default configuration, number 0,
+// which is valid for material in the vacinity of QCIF/QVGA.
+//
+// Updating The Configuration
+// ---------------------------------
+// Almost all applications will want to update the default configuration
+// with settings specific to their usage. Here we set the width and height
+// of the video file to that specified on the command line. We also scale
+// the default bitrate based on the ratio between the default resolution
+// and the resolution specified on the command line.
+//
+// Encoding A Frame
+// ----------------
+// The frame is read as a continuous block (size = width * height * 3 / 2)
+// from the input file. If a frame was read (the input file has not hit
+// EOF) then the frame is passed to the encoder. Otherwise, a NULL
+// is passed, indicating the End-Of-Stream condition to the encoder. The
+// `frame_cnt` is reused as the presentation time stamp (PTS) and each
+// frame is shown for one frame-time in duration. The flags parameter is
+// unused in this example.
+
+// Forced Keyframes
+// ----------------
+// Keyframes can be forced by setting the AOM_EFLAG_FORCE_KF bit of the
+// flags passed to `aom_codec_control()`. In this example, we force a
+// keyframe every <keyframe-interval> frames. Note, the output stream can
+// contain additional keyframes beyond those that have been forced using the
+// AOM_EFLAG_FORCE_KF flag because of automatic keyframe placement by the
+// encoder.
+//
+// Processing The Encoded Data
+// ---------------------------
+// Each packet of type `AOM_CODEC_CX_FRAME_PKT` contains the encoded data
+// for this frame. We write a IVF frame header, followed by the raw data.
+//
+// Cleanup
+// -------
+// The `aom_codec_destroy` call frees any memory allocated by the codec.
+//
+// Error Handling
+// --------------
+// This example does not special case any error return codes. If there was
+// an error, a descriptive message is printed and the program exits. With
+// few exeptions, aom_codec functions return an enumerated error status,
+// with the value `0` indicating success.

+// AOM Set Active and ROI Maps
+// ===========================
+//
+// This is an example demonstrating how to control the AOM encoder's
+// ROI and Active maps.
+//
+// ROI (Reigon of Interest) maps are a way for the application to assign
+// each macroblock in the image to a region, and then set quantizer and
+// filtering parameters on that image.
+//
+// Active maps are a way for the application to specify on a
+// macroblock-by-macroblock basis whether there is any activity in that
+// macroblock.
+//
+//
+// Configuration
+// -------------
+// An ROI map is set on frame 22. If the width of the image in macroblocks
+// is evenly divisble by 4, then the output will appear to have distinct
+// columns, where the quantizer, loopfilter, and static threshold differ
+// from column to column.
+//
+// An active map is set on frame 33. If the width of the image in macroblocks
+// is evenly divisble by 4, then the output will appear to have distinct
+// columns, where one column will have motion and the next will not.
+//
+// The active map is cleared on frame 44.
+//
+// Observing The Effects
+// ---------------------
+// Use the `simple_decoder` example to decode this sample, and observe
+// the change in the image at frames 22, 33, and 44.

+// Simple Decoder
+// ==============
+//
+// This is an example of a simple decoder loop. It takes an input file
+// containing the compressed data (in IVF format), passes it through the
+// decoder, and writes the decompressed frames to disk. Other decoder
+// examples build upon this one.
+//
+// The details of the IVF format have been elided from this example for
+// simplicity of presentation, as IVF files will not generally be used by
+// your application. In general, an IVF file consists of a file header,
+// followed by a variable number of frames. Each frame consists of a frame
+// header followed by a variable length payload. The length of the payload
+// is specified in the first four bytes of the frame header. The payload is
+// the raw compressed data.
+//
+// Standard Includes
+// -----------------
+// For decoders, you only have to include `aom_decoder.h` and then any
+// header files for the specific codecs you use. In this case, we're using
+// aom.
+//
+// Initializing The Codec
+// ----------------------
+// The libaom decoder is initialized by the call to aom_codec_dec_init().
+// Determining the codec interface to use is handled by AvxVideoReader and the
+// functions prefixed with aom_video_reader_. Discussion of those functions is
+// beyond the scope of this example, but the main gist is to open the input file
+// and parse just enough of it to determine if it's a AVx file and which AVx
+// codec is contained within the file.
+// Note the NULL pointer passed to aom_codec_dec_init(). We do that in this
+// example because we want the algorithm to determine the stream configuration
+// (width/height) and allocate memory automatically.
+//
+// Decoding A Frame
+// ----------------
+// Once the frame has been read into memory, it is decoded using the
+// `aom_codec_decode` function. The call takes a pointer to the data
+// (`frame`) and the length of the data (`frame_size`). No application data
+// is associated with the frame in this example, so the `user_priv`
+// parameter is NULL.
+//
+// Codecs may produce a variable number of output frames for every call to
+// `aom_codec_decode`. These frames are retrieved by the
+// `aom_codec_get_frame` iterator function. The iterator variable `iter` is
+// initialized to NULL each time `aom_codec_decode` is called.
+// `aom_codec_get_frame` is called in a loop, returning a pointer to a
+// decoded image or NULL to indicate the end of list.
+//
+// Processing The Decoded Data
+// ---------------------------
+// In this example, we simply write the encoded data to disk. It is
+// important to honor the image's `stride` values.
+//
+// Cleanup
+// -------
+// The `aom_codec_destroy` call frees any memory allocated by the codec.
+//
+// Error Handling
+// --------------
+// This example does not special case any error return codes. If there was
+// an error, a descriptive message is printed and the program exits. With
+// few exceptions, aom_codec functions return an enumerated error status,
+// with the value `0` indicating success.

+// Simple Encoder
+// ==============
+//
+// This is an example of a simple encoder loop. It takes an input file in
+// YV12 format, passes it through the encoder, and writes the compressed
+// frames to disk in IVF format. Other decoder examples build upon this
+// one.
+//
+// The details of the IVF format have been elided from this example for
+// simplicity of presentation, as IVF files will not generally be used by
+// your application. In general, an IVF file consists of a file header,
+// followed by a variable number of frames. Each frame consists of a frame
+// header followed by a variable length payload. The length of the payload
+// is specified in the first four bytes of the frame header. The payload is
+// the raw compressed data.
+//
+// Standard Includes
+// -----------------
+// For encoders, you only have to include `aom_encoder.h` and then any
+// header files for the specific codecs you use. In this case, we're using
+// aom.
+//
+// Getting The Default Configuration
+// ---------------------------------
+// Encoders have the notion of "usage profiles." For example, an encoder
+// may want to publish default configurations for both a video
+// conferencing application and a best quality offline encoder. These
+// obviously have very different default settings. Consult the
+// documentation for your codec to see if it provides any default
+// configurations. All codecs provide a default configuration, number 0,
+// which is valid for material in the vacinity of QCIF/QVGA.
+//
+// Updating The Configuration
+// ---------------------------------
+// Almost all applications will want to update the default configuration
+// with settings specific to their usage. Here we set the width and height
+// of the video file to that specified on the command line. We also scale
+// the default bitrate based on the ratio between the default resolution
+// and the resolution specified on the command line.
+//
+// Initializing The Codec
+// ----------------------
+// The encoder is initialized by the following code.
+//
+// Encoding A Frame
+// ----------------
+// The frame is read as a continuous block (size width * height * 3 / 2)
+// from the input file. If a frame was read (the input file has not hit
+// EOF) then the frame is passed to the encoder. Otherwise, a NULL
+// is passed, indicating the End-Of-Stream condition to the encoder. The
+// `frame_cnt` is reused as the presentation time stamp (PTS) and each
+// frame is shown for one frame-time in duration. The flags parameter is
+// unused in this example.
+
+// Forced Keyframes
+// ----------------
+// Keyframes can be forced by setting the AOM_EFLAG_FORCE_KF bit of the
+// flags passed to `aom_codec_control()`. In this example, we force a
+// keyframe every <keyframe-interval> frames. Note, the output stream can
+// contain additional keyframes beyond those that have been forced using the
+// AOM_EFLAG_FORCE_KF flag because of automatic keyframe placement by the
+// encoder.
+//
+// Processing The Encoded Data
+// ---------------------------
+// Each packet of type `AOM_CODEC_CX_FRAME_PKT` contains the encoded data
+// for this frame. We write a IVF frame header, followed by the raw data.
+//
+// Cleanup
+// -------
+// The `aom_codec_destroy` call frees any memory allocated by the codec.
+//
+// Error Handling
+// --------------
+// This example does not special case any error return codes. If there was
+// an error, a descriptive message is printed and the program exits. With
+// few exeptions, aom_codec functions return an enumerated error status,
+// with the value `0` indicating success.
+//
+// Error Resiliency Features
+// -------------------------
+// Error resiliency is controlled by the g_error_resilient member of the
+// configuration structure. Use the `decode_with_drops` example to decode with
+// frames 5-10 dropped. Compare the output for a file encoded with this example
+// versus one encoded with the `simple_encoder` example.

+/*!\page rfc2119 RFC2119 Keywords
+
+      The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL
+      NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED",  "MAY", and
+      "OPTIONAL" in this document are to be interpreted as described in
+      <a href="http://www.ietf.org/rfc/rfc2119.txt">RFC 2119.</a>
+
+Specifically, the following definitions are used:
+
+\section MUST
+\anchor REQUIRED
+\anchor SHALL
+   This word, or the terms "REQUIRED" or "SHALL", mean that the
+   definition is an absolute requirement of the specification.
+
+\section MUSTNOT MUST NOT
+\anchor SHALLNOT
+   This phrase, or the phrase "SHALL NOT", mean that the
+   definition is an absolute prohibition of the specification.
+
+\section SHOULD
+\anchor RECOMMENDED
+   This word, or the adjective "RECOMMENDED", mean that there
+   may exist valid reasons in particular circumstances to ignore a
+   particular item, but the full implications must be understood and
+   carefully weighed before choosing a different course.
+
+\section SHOULDNOT SHOULD NOT
+\anchor NOTRECOMMENDED
+   This phrase, or the phrase "NOT RECOMMENDED" mean that
+   there may exist valid reasons in particular circumstances when the
+   particular behavior is acceptable or even useful, but the full
+   implications should be understood and the case carefully weighed
+   before implementing any behavior described with this label.
+
+\section MAY
+\anchor OPTIONAL
+   This word, or the adjective "OPTIONAL", mean that an item is
+   truly optional.  One vendor may choose to include the item because a
+   particular marketplace requires it or because the vendor feels that
+   it enhances the product while another vendor may omit the same item.
+   An implementation which does not include a particular option \ref MUST be
+   prepared to interoperate with another implementation which does
+   include the option, though perhaps with reduced functionality. In the
+   same vein an implementation which does include a particular option
+   \ref MUST be prepared to interoperate with another implementation which
+   does not include the option (except, of course, for the feature the
+   option provides.)

+  """Wraps the data to convert to a Google Visualization API DataTable.
+
+  Create this object, populate it with data, then call one of the ToJS...
+  methods to return a string representation of the data in the format described.
+
+  You can clear all data from the object to reuse it, but you cannot clear
+  individual cells, rows, or columns. You also cannot modify the table schema
+  specified in the class constructor.
+
+  You can add new data one or more rows at a time. All data added to an
+  instantiated DataTable must conform to the schema passed in to __init__().
+
+  You can reorder the columns in the output table, and also specify row sorting
+  order by column. The default column order is according to the original
+  table_description parameter. Default row sort order is ascending, by column
+  1 values. For a dictionary, we sort the keys for order.
+
+  The data and the table_description are closely tied, as described here:
+
+  The table schema is defined in the class constructor's table_description
+  parameter. The user defines each column using a tuple of
+  (id[, type[, label[, custom_properties]]]). The default value for type is
+  string, label is the same as ID if not specified, and custom properties is
+  an empty dictionary if not specified.
+
+  table_description is a dictionary or list, containing one or more column
+  descriptor tuples, nested dictionaries, and lists. Each dictionary key, list
+  element, or dictionary element must eventually be defined as
+  a column description tuple. Here's an example of a dictionary where the key
+  is a tuple, and the value is a list of two tuples:
+    {('a', 'number'): [('b', 'number'), ('c', 'string')]}
+
+  This flexibility in data entry enables you to build and manipulate your data
+  in a Python structure that makes sense for your program.
+
+  Add data to the table using the same nested design as the table's
+  table_description, replacing column descriptor tuples with cell data, and
+  each row is an element in the top level collection. This will be a bit
+  clearer after you look at the following examples showing the
+  table_description, matching data, and the resulting table:
+
+  Columns as list of tuples [col1, col2, col3]
+    table_description: [('a', 'number'), ('b', 'string')]
+    AppendData( [[1, 'z'], [2, 'w'], [4, 'o'], [5, 'k']] )
+    Table:
+    a  b   <--- these are column ids/labels
+    1  z
+    2  w
+    4  o
+    5  k
+
+  Dictionary of columns, where key is a column, and value is a list of
+  columns  {col1: [col2, col3]}
+    table_description: {('a', 'number'): [('b', 'number'), ('c', 'string')]}
+    AppendData( data: {1: [2, 'z'], 3: [4, 'w']}
+    Table:
+    a  b  c
+    1  2  z
+    3  4  w
+
+  Dictionary where key is a column, and the value is itself a dictionary of
+  columns {col1: {col2, col3}}
+    table_description: {('a', 'number'): {'b': 'number', 'c': 'string'}}
+    AppendData( data: {1: {'b': 2, 'c': 'z'}, 3: {'b': 4, 'c': 'w'}}

+Description:
+Library to compute FAST features with non-maximum suppression.
+
+The files are valid C and C++ code, and have no special requirements for
+compiling, and they do not depend on any libraries. Just compile them along with
+the rest of your project.
+
+To use the functions, #include "fast.h"
+
+The corner detectors have the following prototype (where X is 9, 10, 11 or 12):
+
+xy* fastX_detect_nonmax(const unsigned char * data, int xsize, int ysize, int stride, int threshold, int* numcorners)
+
+Where xy is the following simple struct typedef:
+
+typedef struct
+{
+	int x, y;
+} xy;
+
+The image is passed in as a block of data and dimensions, and the list of
+corners is returned as an array of xy structs, and an integer (numcorners)
+with the number of corners returned.  The data can be deallocated with free().
+Nonmaximal suppression is performed on the corners. Note that the stride
+is the number of bytes between rows. If your image has no padding, then this
+is the same as xsize.
+
+The detection, scoring and nonmaximal suppression are available as individual
+functions.  To see how to use the individual functions, see fast.c
+
+Local Modifications:
+Add lines to turn off clang formatting for these files
+Remove Fast 10, 11 and 12
+Convert tabs to spaces

+Changes for 1.7.0:
+
+* New feature: death tests are supported on OpenBSD and in iOS
+  simulator now.
+* New feature: Google Test now implements a protocol to allow
+  a test runner to detect that a test program has exited
+  prematurely and report it as a failure (before it would be
+  falsely reported as a success if the exit code is 0).
+* New feature: Test::RecordProperty() can now be used outside of the
+  lifespan of a test method, in which case it will be attributed to
+  the current test case or the test program in the XML report.
+* New feature (potentially breaking): --gtest_list_tests now prints
+  the type parameters and value parameters for each test.
+* Improvement: char pointers and char arrays are now escaped properly
+  in failure messages.
+* Improvement: failure summary in XML reports now includes file and
+  line information.
+* Improvement: the <testsuites> XML element now has a timestamp attribute.
+* Improvement: When --gtest_filter is specified, XML report now doesn't
+  contain information about tests that are filtered out.
+* Fixed the bug where long --gtest_filter flag values are truncated in
+  death tests.
+* Potentially breaking change: RUN_ALL_TESTS() is now implemented as a
+  function instead of a macro in order to work better with Clang.
+* Compatibility fixes with C++ 11 and various platforms.
+* Bug/warning fixes.
+
+Changes for 1.6.0:
+
+* New feature: ADD_FAILURE_AT() for reporting a test failure at the
+  given source location -- useful for writing testing utilities.
+* New feature: the universal value printer is moved from Google Mock
+  to Google Test.
+* New feature: type parameters and value parameters are reported in
+  the XML report now.
+* A gtest_disable_pthreads CMake option.
+* Colored output works in GNU Screen sessions now.
+* Parameters of value-parameterized tests are now printed in the
+  textual output.
+* Failures from ad hoc test assertions run before RUN_ALL_TESTS() are
+  now correctly reported.
+* Arguments of ASSERT_XY and EXPECT_XY no longer need to support << to
+  ostream.
+* More complete handling of exceptions.
+* GTEST_ASSERT_XY can be used instead of ASSERT_XY in case the latter
+  name is already used by another library.
+* --gtest_catch_exceptions is now true by default, allowing a test
+  program to continue after an exception is thrown.
+* Value-parameterized test fixtures can now derive from Test and
+  WithParamInterface<T> separately, easing conversion of legacy tests.
+* Death test messages are clearly marked to make them more
+  distinguishable from other messages.
+* Compatibility fixes for Android, Google Native Client, MinGW, HP UX,
+  PowerPC, Lucid autotools, libCStd, Sun C++, Borland C++ Builder (Code Gear),
+  IBM XL C++ (Visual Age C++), and C++0x.
+* Bug fixes and implementation clean-ups.
+* Potentially incompatible changes: disables the harmful 'make install'
+  command in autotools.
+
+Changes for 1.5.0:
+
+ * New feature: assertions can be safely called in multiple threads
+   where the pthreads library is available.
+ * New feature: predicates used inside EXPECT_TRUE() and friends
+   can now generate custom failure messages.
+ * New feature: Google Test can now be compiled as a DLL.
+ * New feature: fused source files are included.
+ * New feature: prints help when encountering unrecognized Google Test flags.
+ * Experimental feature: CMake build script (requires CMake 2.6.4+).
+ * Experimental feature: the Pump script for meta programming.
+ * double values streamed to an assertion are printed with enough precision
+   to differentiate any two different values.
+ * Google Test now works on Solaris and AIX.
+ * Build and test script improvements.
+ * Bug fixes and implementation clean-ups.
+
+ Potentially breaking changes:
+
+ * Stopped supporting VC++ 7.1 with exceptions disabled.
+ * Dropped support for 'make install'.
+
+Changes for 1.4.0:
+
+ * New feature: the event listener API
+ * New feature: test shuffling
+ * New feature: the XML report format is closer to junitreport and can
+   be parsed by Hudson now.
+ * New feature: when a test runs under Visual Studio, its failures are
+   integrated in the IDE.
+ * New feature: /MD(d) versions of VC++ projects.
+ * New feature: elapsed time for the tests is printed by default.
+ * New feature: comes with a TR1 tuple implementation such that Boost
+   is no longer needed for Combine().
+ * New feature: EXPECT_DEATH_IF_SUPPORTED macro and friends.
+ * New feature: the Xcode project can now produce static gtest
+   libraries in addition to a framework.
+ * Compatibility fixes for Solaris, Cygwin, minGW, Windows Mobile,
+   Symbian, gcc, and C++Builder.
+ * Bug fixes and implementation clean-ups.
+
+Changes for 1.3.0:
+
+ * New feature: death tests on Windows, Cygwin, and Mac.
+ * New feature: ability to use Google Test assertions in other testing
+   frameworks.
+ * New feature: ability to run disabled test via
+   --gtest_also_run_disabled_tests.
+ * New feature: the --help flag for printing the usage.
+ * New feature: access to Google Test flag values in user code.
+ * New feature: a script that packs Google Test into one .h and one
+   .cc file for easy deployment.
+ * New feature: support for distributing test functions to multiple
+   machines (requires support from the test runner).
+ * Bug fixes and implementation clean-ups.
+
+Changes for 1.2.1:
+
+ * Compatibility fixes for Linux IA-64 and IBM z/OS.
+ * Added support for using Boost and other TR1 implementations.
+ * Changes to the build scripts to support upcoming release of Google C++
+   Mocking Framework.
+ * Added Makefile to the distribution package.
+ * Improved build instructions in README.
+
+Changes for 1.2.0:
+
+ * New feature: value-parameterized tests.
+ * New feature: the ASSERT/EXPECT_(NON)FATAL_FAILURE(_ON_ALL_THREADS)
+   macros.
+ * Changed the XML report format to match JUnit/Ant's.
+ * Added tests to the Xcode project.
+ * Added scons/SConscript for building with SCons.
+ * Added src/gtest-all.cc for building Google Test from a single file.
+ * Fixed compatibility with Solaris and z/OS.
+ * Enabled running Python tests on systems with python 2.3 installed,
+   e.g. Mac OS X 10.4.
+ * Bug fixes.
+
+Changes for 1.1.0:
+
+ * New feature: type-parameterized tests.
+ * New feature: exception assertions.
+ * New feature: printing elapsed time of tests.
+ * Improved the robustness of death tests.

+### Generic Build Instructions ###
+
+#### Setup ####
+
+To build Google Test and your tests that use it, you need to tell your
+build system where to find its headers and source files.  The exact
+way to do it depends on which build system you use, and is usually
+straightforward.
+
+#### Build ####
+
+Suppose you put Google Test in directory `${GTEST_DIR}`.  To build it,
+create a library build target (or a project as called by Visual Studio
+and Xcode) to compile
+
+    ${GTEST_DIR}/src/gtest-all.cc
+
+with `${GTEST_DIR}/include` in the system header search path and `${GTEST_DIR}`
+in the normal header search path.  Assuming a Linux-like system and gcc,
+something like the following will do:
+
+    g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
+        -pthread -c ${GTEST_DIR}/src/gtest-all.cc
+    ar -rv libgtest.a gtest-all.o
+
+(We need `-pthread` as Google Test uses threads.)
+
+Next, you should compile your test source file with
+`${GTEST_DIR}/include` in the system header search path, and link it
+with gtest and any other necessary libraries:
+
+    g++ -isystem ${GTEST_DIR}/include -pthread path/to/your_test.cc libgtest.a \
+        -o your_test
+
+As an example, the make/ directory contains a Makefile that you can
+use to build Google Test on systems where GNU make is available
+(e.g. Linux, Mac OS X, and Cygwin).  It doesn't try to build Google
+Test's own tests.  Instead, it just builds the Google Test library and
+a sample test.  You can use it as a starting point for your own build
+script.
+
+If the default settings are correct for your environment, the
+following commands should succeed:
+
+    cd ${GTEST_DIR}/make
+    make
+    ./sample1_unittest
+
+If you see errors, try to tweak the contents of `make/Makefile` to make
+them go away.  There are instructions in `make/Makefile` on how to do
+it.
+
+### Using CMake ###
+
+Google Test comes with a CMake build script (
+[CMakeLists.txt](CMakeLists.txt)) that can be used on a wide range of platforms ("C" stands for
+cross-platform.). If you don't have CMake installed already, you can
+download it for free from <http://www.cmake.org/>.
+
+CMake works by generating native makefiles or build projects that can
+be used in the compiler environment of your choice.  The typical
+workflow starts with:
+
+    mkdir mybuild       # Create a directory to hold the build output.
+    cd mybuild
+    cmake ${GTEST_DIR}  # Generate native build scripts.
+
+If you want to build Google Test's samples, you should replace the
+last command with
+
+    cmake -Dgtest_build_samples=ON ${GTEST_DIR}
+
+If you are on a \*nix system, you should now see a Makefile in the
+current directory.  Just type 'make' to build gtest.
+
+If you use Windows and have Visual Studio installed, a `gtest.sln` file
+and several `.vcproj` files will be created.  You can then build them
+using Visual Studio.
+
+On Mac OS X with Xcode installed, a `.xcodeproj` file will be generated.
+
+### Legacy Build Scripts ###
+
+Before settling on CMake, we have been providing hand-maintained build
+projects/scripts for Visual Studio, Xcode, and Autotools.  While we
+continue to provide them for convenience, they are not actively
+maintained any more.  We highly recommend that you follow the
+instructions in the previous two sections to integrate Google Test
+with your existing build system.
+
+If you still need to use the legacy build scripts, here's how:
+
+The msvc\ folder contains two solutions with Visual C++ projects.
+Open the `gtest.sln` or `gtest-md.sln` file using Visual Studio, and you
+are ready to build Google Test the same way you build any Visual
+Studio project.  Files that have names ending with -md use DLL
+versions of Microsoft runtime libraries (the /MD or the /MDd compiler
+option).  Files without that suffix use static versions of the runtime
+libraries (the /MT or the /MTd option).  Please note that one must use
+the same option to compile both gtest and the test code.  If you use
+Visual Studio 2005 or above, we recommend the -md version as /MD is
+the default for new projects in these versions of Visual Studio.
+
+On Mac OS X, open the `gtest.xcodeproj` in the `xcode/` folder using
+Xcode.  Build the "gtest" target.  The universal binary framework will
+end up in your selected build directory (selected in the Xcode
+"Preferences..." -> "Building" pane and defaults to xcode/build).
+Alternatively, at the command line, enter:
+
+    xcodebuild
+
+This will build the "Release" configuration of gtest.framework in your
+default build location.  See the "xcodebuild" man page for more
+information about building different configurations and building in
+different locations.
+
+If you wish to use the Google Test Xcode project with Xcode 4.x and
+above, you need to either:
+
+ * update the SDK configuration options in xcode/Config/General.xconfig.
+   Comment options `SDKROOT`, `MACOS_DEPLOYMENT_TARGET`, and `GCC_VERSION`. If
+   you choose this route you lose the ability to target earlier versions
+   of MacOS X.
+ * Install an SDK for an earlier version. This doesn't appear to be
+   supported by Apple, but has been reported to work
+   (http://stackoverflow.com/questions/5378518).
+
+### Tweaking Google Test ###
+
+Google Test can be used in diverse environments.  The default
+configuration may not work (or may not work well) out of the box in
+some environments.  However, you can easily tweak Google Test by
+defining control macros on the compiler command line.  Generally,
+these macros are named like `GTEST_XYZ` and you define them to either 1
+or 0 to enable or disable a certain feature.
+
+We list the most frequently used macros below.  For a complete list,
+see file [include/gtest/internal/gtest-port.h](include/gtest/internal/gtest-port.h).
+
+### Choosing a TR1 Tuple Library ###
+
+Some Google Test features require the C++ Technical Report 1 (TR1)
+tuple library, which is not yet available with all compilers.  The
+good news is that Google Test implements a subset of TR1 tuple that's
+enough for its own need, and will automatically use this when the
+compiler doesn't provide TR1 tuple.
+
+Usually you don't need to care about which tuple library Google Test
+uses.  However, if your project already uses TR1 tuple, you need to
+tell Google Test to use the same TR1 tuple library the rest of your
+project uses, or the two tuple implementations will clash.  To do
+that, add
+
+    -DGTEST_USE_OWN_TR1_TUPLE=0
+
+to the compiler flags while compiling Google Test and your tests.  If
+you want to force Google Test to use its own tuple library, just add
+
+    -DGTEST_USE_OWN_TR1_TUPLE=1
+
+to the compiler flags instead.
+
+If you don't want Google Test to use tuple at all, add
+
+    -DGTEST_HAS_TR1_TUPLE=0
+
+and all features using tuple will be disabled.
+
+### Multi-threaded Tests ###
+
+Google Test is thread-safe where the pthread library is available.
+After `#include "gtest/gtest.h"`, you can check the `GTEST_IS_THREADSAFE`
+macro to see whether this is the case (yes if the macro is `#defined` to
+1, no if it's undefined.).
+
+If Google Test doesn't correctly detect whether pthread is available
+in your environment, you can force it with
+
+    -DGTEST_HAS_PTHREAD=1
+
+or
+
+    -DGTEST_HAS_PTHREAD=0
+
+When Google Test uses pthread, you may need to add flags to your
+compiler and/or linker to select the pthread library, or you'll get
+link errors.  If you use the CMake script or the deprecated Autotools
+script, this is taken care of for you.  If you use your own build
+script, you'll need to read your compiler and linker's manual to
+figure out what flags to add.
+
+### As a Shared Library (DLL) ###
+
+Google Test is compact, so most users can build and link it as a
+static library for the simplicity.  You can choose to use Google Test
+as a shared library (known as a DLL on Windows) if you prefer.
+
+To compile *gtest* as a shared library, add
+
+    -DGTEST_CREATE_SHARED_LIBRARY=1
+
+to the compiler flags.  You'll also need to tell the linker to produce
+a shared library instead - consult your linker's manual for how to do
+it.
+
+To compile your *tests* that use the gtest shared library, add
+
+    -DGTEST_LINKED_AS_SHARED_LIBRARY=1
+
+to the compiler flags.
+
+Note: while the above steps aren't technically necessary today when
+using some compilers (e.g. GCC), they may become necessary in the
+future, if we decide to improve the speed of loading the library (see
+<http://gcc.gnu.org/wiki/Visibility> for details).  Therefore you are
+recommended to always add the above flags when using Google Test as a
+shared library.  Otherwise a future release of Google Test may break
+your build script.
+
+### Avoiding Macro Name Clashes ###
+
+In C++, macros don't obey namespaces.  Therefore two libraries that
+both define a macro of the same name will clash if you `#include` both
+definitions.  In case a Google Test macro clashes with another
+library, you can force Google Test to rename its macro to avoid the
+conflict.
+
+Specifically, if both Google Test and some other code define macro
+FOO, you can add
+
+    -DGTEST_DONT_DEFINE_FOO=1
+
+to the compiler flags to tell Google Test to change the macro's name
+from `FOO` to `GTEST_FOO`.  Currently `FOO` can be `FAIL`, `SUCCEED`,
+or `TEST`.  For example, with `-DGTEST_DONT_DEFINE_TEST=1`, you'll
+need to write
+
+    GTEST_TEST(SomeTest, DoesThis) { ... }
+
+instead of
+
+    TEST(SomeTest, DoesThis) { ... }
+
+in order to define a test.
+
+## Developing Google Test ##
+
+This section discusses how to make your own changes to Google Test.
+
+### Testing Google Test Itself ###
+
+To make sure your changes work as intended and don't break existing
+functionality, you'll want to compile and run Google Test's own tests.
+For that you can use CMake:
+
+    mkdir mybuild
+    cd mybuild
+    cmake -Dgtest_build_tests=ON ${GTEST_DIR}
+
+Make sure you have Python installed, as some of Google Test's tests
+are written in Python.  If the cmake command complains about not being
+able to find Python (`Could NOT find PythonInterp (missing:
+PYTHON_EXECUTABLE)`), try telling it explicitly where your Python
+executable can be found:
+
+    cmake -DPYTHON_EXECUTABLE=path/to/python -Dgtest_build_tests=ON ${GTEST_DIR}
+
+Next, you can build Google Test and all of its own tests.  On \*nix,
+this is usually done by 'make'.  To run the tests, do
+
+    make test
+
+All tests should pass.
+
+Normally you don't need to worry about regenerating the source files,
+unless you need to modify them.  In that case, you should modify the
+corresponding .pump files instead and run the pump.py Python script to
+regenerate them.  You can find pump.py in the [scripts/](scripts/) directory.
+Read the [Pump manual](docs/PumpManual.md) for how to use it.

+// The following macros are useful for writing death tests.
+
+// Here's what happens when an ASSERT_DEATH* or EXPECT_DEATH* is
+// executed:
+//
+//   1. It generates a warning if there is more than one active
+//   thread.  This is because it's safe to fork() or clone() only
+//   when there is a single thread.
+//
+//   2. The parent process clone()s a sub-process and runs the death
+//   test in it; the sub-process exits with code 0 at the end of the
+//   death test, if it hasn't exited already.
+//
+//   3. The parent process waits for the sub-process to terminate.
+//
+//   4. The parent process checks the exit code and error message of
+//   the sub-process.
+//
+// Examples:
+//
+//   ASSERT_DEATH(server.SendMessage(56, "Hello"), "Invalid port number");
+//   for (int i = 0; i < 5; i++) {
+//     EXPECT_DEATH(server.ProcessRequest(i),
+//                  "Invalid request .* in ProcessRequest()")
+//                  << "Failed to die on request " << i;
+//   }
+//
+//   ASSERT_EXIT(server.ExitNow(), ::testing::ExitedWithCode(0), "Exiting");
+//
+//   bool KilledBySIGHUP(int exit_code) {
+//     return WIFSIGNALED(exit_code) && WTERMSIG(exit_code) == SIGHUP;
+//   }
+//
+//   ASSERT_EXIT(client.HangUpServer(), KilledBySIGHUP, "Hanging up!");
+//
+// On the regular expressions used in death tests:
+//
+//   On POSIX-compliant systems (*nix), we use the <regex.h> library,
+//   which uses the POSIX extended regex syntax.
+//
+//   On other platforms (e.g. Windows), we only support a simple regex
+//   syntax implemented as part of Google Test.  This limited
+//   implementation should be enough most of the time when writing
+//   death tests; though it lacks many features you can find in PCRE
+//   or POSIX extended regex syntax.  For example, we don't support
+//   union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and
+//   repetition count ("x{5,7}"), among others.
+//
+//   Below is the syntax that we do support.  We chose it to be a
+//   subset of both PCRE and POSIX extended regex, so it's easy to
+//   learn wherever you come from.  In the following: 'A' denotes a
+//   literal character, period (.), or a single \\ escape sequence;
+//   'x' and 'y' denote regular expressions; 'm' and 'n' are for
+//   natural numbers.
+//
+//     c     matches any literal character c
+//     \\d   matches any decimal digit
+//     \\D   matches any character that's not a decimal digit
+//     \\f   matches \f
+//     \\n   matches \n
+//     \\r   matches \r
+//     \\s   matches any ASCII whitespace, including \n
+//     \\S   matches any character that's not a whitespace
+//     \\t   matches \t
+//     \\v   matches \v
+//     \\w   matches any letter, _, or decimal digit
+//     \\W   matches any character that \\w doesn't match
+//     \\c   matches any literal character c, which must be a punctuation
+//     .     matches any single character except \n
+//     A?    matches 0 or 1 occurrences of A
+//     A*    matches 0 or many occurrences of A
+//     A+    matches 1 or many occurrences of A
+//     ^     matches the beginning of a string (not that of each line)
+//     $     matches the end of a string (not that of each line)
+//     xy    matches x followed by y
+//
+//   If you accidentally use PCRE or POSIX extended regex features
+//   not implemented by us, you will get a run-time failure.  In that
+//   case, please try to rewrite your regular expression within the
+//   above syntax.
+//
+//   This implementation is *not* meant to be as highly tuned or robust
+//   as a compiled regex library, but should perform well enough for a
+//   death test, which already incurs significant overhead by launching
+//   a child process.
+//
+// Known caveats:
+//
+//   A "threadsafe" style death test obtains the path to the test
+//   program from argv[0] and re-executes it in the sub-process.  For
+//   simplicity, the current implementation doesn't search the PATH
+//   when launching the sub-process.  This means that the user must
+//   invoke the test program via a path that contains at least one
+//   path separator (e.g. path/to/foo_test and
+//   /absolute/path/to/bar_test are fine, but foo_test is not).  This
+//   is rarely a problem as people usually don't put the test binary
+//   directory in PATH.
+//
+// TODO(wan@google.com): make thread-safe death tests search the PATH.

+// Value-parameterized tests allow you to test your code with different

+//
+// Here is how you use value-parameterized tests:
+
+#if 0
+
+// To write value-parameterized tests, first you should define a fixture
+// class. It is usually derived from testing::TestWithParam<T> (see below for
+// another inheritance scheme that's sometimes useful in more complicated
+// class hierarchies), where the type of your parameter values.
+// TestWithParam<T> is itself derived from testing::Test. T can be any
+// copyable type. If it's a raw pointer, you are responsible for managing the
+// lifespan of the pointed values.
+
+class FooTest : public ::testing::TestWithParam<const char*> {
+  // You can implement all the usual class fixture members here.
+};
+
+// Then, use the TEST_P macro to define as many parameterized tests
+// for this fixture as you want. The _P suffix is for "parameterized"
+// or "pattern", whichever you prefer to think.
+
+TEST_P(FooTest, DoesBlah) {
+  // Inside a test, access the test parameter with the GetParam() method
+  // of the TestWithParam<T> class:
+  EXPECT_TRUE(foo.Blah(GetParam()));
+  ...
+}
+
+TEST_P(FooTest, HasBlahBlah) {
+  ...
+}
+
+// Finally, you can use INSTANTIATE_TEST_CASE_P to instantiate the test
+// case with any set of parameters you want. Google Test defines a number
+// of functions for generating test parameters. They return what we call
+// (surprise!) parameter generators. Here is a  summary of them, which
+// are all in the testing namespace:
+//
+//
+//  Range(begin, end [, step]) - Yields values {begin, begin+step,
+//                               begin+step+step, ...}. The values do not
+//                               include end. step defaults to 1.
+//  Values(v1, v2, ..., vN)    - Yields values {v1, v2, ..., vN}.
+//  ValuesIn(container)        - Yields values from a C-style array, an STL
+//  ValuesIn(begin,end)          container, or an iterator range [begin, end).
+//  Bool()                     - Yields sequence {false, true}.
+//  Combine(g1, g2, ..., gN)   - Yields all combinations (the Cartesian product
+//                               for the math savvy) of the values generated
+//                               by the N generators.
+//
+// For more details, see comments at the definitions of these functions below
+// in this file.

+
+// To distinguish different instances of the pattern, (yes, you
+// can instantiate it more then once) the first argument to the
+// INSTANTIATE_TEST_CASE_P macro is a prefix that will be added to the
+// actual test case name. Remember to pick unique prefixes for different

+// Please note that INSTANTIATE_TEST_CASE_P will instantiate all tests
+// in the given test case, whether their definitions come before or

+// Please also note that generator expressions (including parameters to the

+// to dynamically determine a set of tests to run and on the other hand,
+// give the user a chance to inspect the generated tests with Google Test
+// reflection API before RUN_ALL_TESTS() is executed.
+//
+// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
+// for more examples.

+// In the future, we plan to publish the API for defining new parameter
+// generators. But for now this interface remains part of the internal

+// complicated hierarchies, however, it is occasionally useful to inherit
+// separately from Test and WithParamInterface. For example:
+
+class BaseTest : public ::testing::Test {

+//   - returns a generator producing sequences with elements coming from
+//     the Cartesian product of elements from the sequences generated by
+//     gen1, gen2, ..., genN. The sequence elements will have a type of
+//     tuple<T1, T2, ..., TN> where T1, T2, ..., TN are the types
+//     of elements from sequences produces by gen1, gen2, ..., genN.
+//
+// Combine can have up to 10 arguments. This number is currently limited
+// by the maximum number of elements in the tuple implementation used by Google
+// Test.
+//
+// Example:
+//
+// This will instantiate tests in test case AnimalTest each one with
+// the parameter values tuple("cat", BLACK), tuple("cat", WHITE),
+// tuple("dog", BLACK), and tuple("dog", WHITE):
+//
+// enum Color { BLACK, GRAY, WHITE };

+//                                 Values(BLACK, WHITE)));
+//
+// This will instantiate tests in FlagDependentTest with all variations of two
+// Boolean flags:
+//
+// class FlagDependentTest
+//     : public testing::TestWithParam<tuple<bool, bool> > {
+//   virtual void SetUp() {
+//     // Assigns external_flag_1 and external_flag_2 values from the tuple.

+// Here is how you use value-parameterized tests:
+
+#if 0
+
+// To write value-parameterized tests, first you should define a fixture
+// class. It is usually derived from testing::TestWithParam<T> (see below for
+// another inheritance scheme that's sometimes useful in more complicated
+// class hierarchies), where the type of your parameter values.
+// TestWithParam<T> is itself derived from testing::Test. T can be any
+// copyable type. If it's a raw pointer, you are responsible for managing the
+// lifespan of the pointed values.
+
+class FooTest : public ::testing::TestWithParam<const char*> {
+  // You can implement all the usual class fixture members here.
+};
+
+// Then, use the TEST_P macro to define as many parameterized tests
+// for this fixture as you want. The _P suffix is for "parameterized"
+// or "pattern", whichever you prefer to think.
+
+TEST_P(FooTest, DoesBlah) {
+  // Inside a test, access the test parameter with the GetParam() method
+  // of the TestWithParam<T> class:

+}
+
+// Finally, you can use INSTANTIATE_TEST_CASE_P to instantiate the test
+// case with any set of parameters you want. Google Test defines a number
+// of functions for generating test parameters. They return what we call
+// (surprise!) parameter generators. Here is a  summary of them, which
+// are all in the testing namespace:
+//
+//
+//  Range(begin, end [, step]) - Yields values {begin, begin+step,
+//                               begin+step+step, ...}. The values do not
+//                               include end. step defaults to 1.
+//  Values(v1, v2, ..., vN)    - Yields values {v1, v2, ..., vN}.
+//  ValuesIn(container)        - Yields values from a C-style array, an STL
+//  ValuesIn(begin,end)          container, or an iterator range [begin, end).
+//  Bool()                     - Yields sequence {false, true}.
+//  Combine(g1, g2, ..., gN)   - Yields all combinations (the Cartesian product
+//                               for the math savvy) of the values generated
+//                               by the N generators.
+//
+// For more details, see comments at the definitions of these functions below
+// in this file.

+
+// To distinguish different instances of the pattern, (yes, you
+// can instantiate it more then once) the first argument to the
+// INSTANTIATE_TEST_CASE_P macro is a prefix that will be added to the

+//    * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
+//
+// You can use these names in --gtest_filter.

+//
+// Please note that INSTANTIATE_TEST_CASE_P will instantiate all tests
+// in the given test case, whether their definitions come before or
+// AFTER the INSTANTIATE_TEST_CASE_P statement.
+//
+// Please also note that generator expressions (including parameters to the
+// generators) are evaluated in InitGoogleTest(), after main() has started.
+// This allows the user on one hand, to adjust generator parameters in order
+// to dynamically determine a set of tests to run and on the other hand,
+// give the user a chance to inspect the generated tests with Google Test
+// reflection API before RUN_ALL_TESTS() is executed.
+//
+// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
+// for more examples.
+//
+// In the future, we plan to publish the API for defining new parameter
+// generators. But for now this interface remains part of the internal

+// A parameterized test fixture must be derived from testing::Test and from

+// complicated hierarchies, however, it is occasionally useful to inherit
+// separately from Test and WithParamInterface. For example:

+// This file implements a universal value printer that can print a
+// value of any type T:
+//
+//   void ::testing::internal::UniversalPrinter<T>::Print(value, ostream_ptr);
+//
+// A user can teach this function how to print a class type T by
+// defining either operator<<() or PrintTo() in the namespace that
+// defines T.  More specifically, the FIRST defined function in the
+// following list will be used (assuming T is defined in namespace
+// foo):
+//
+//   1. foo::PrintTo(const T&, ostream*)
+//   2. operator<<(ostream&, const T&) defined in either foo or the
+//      global namespace.
+//
+// If none of the above is defined, it will print the debug string of
+// the value if it is a protocol buffer, or print the raw bytes in the
+// value otherwise.
+//
+// To aid debugging: when T is a reference type, the address of the
+// value is also printed; when T is a (const) char pointer, both the
+// pointer value and the NUL-terminated string it points to are
+// printed.
+//
+// We also provide some convenient wrappers:
+//
+//   // Prints a value to a string.  For a (const or not) char
+//   // pointer, the NUL-terminated string (but not the pointer) is
+//   // printed.
+//   std::string ::testing::PrintToString(const T& value);
+//
+//   // Prints a value tersely: for a reference type, the referenced
+//   // value (but not the address) is printed; for a (const or not) char
+//   // pointer, the NUL-terminated string (but not the pointer) is
+//   // printed.
+//   void ::testing::internal::UniversalTersePrint(const T& value, ostream*);
+//
+//   // Prints value using the type inferred by the compiler.  The difference
+//   // from UniversalTersePrint() is that this function prints both the
+//   // pointer and the NUL-terminated string for a (const or not) char pointer.
+//   void ::testing::internal::UniversalPrint(const T& value, ostream*);
+//
+//   // Prints the fields of a tuple tersely to a string vector, one
+//   // element for each field. Tuple support must be enabled in
+//   // gtest-port.h.
+//   std::vector<string> UniversalTersePrintTupleFieldsToStrings(
+//       const Tuple& value);
+//
+// Known limitation:
+//
+// The print primitives print the elements of an STL-style container
+// using the compiler-inferred type of *iter where iter is a
+// const_iterator of the container.  When const_iterator is an input
+// iterator but not a forward iterator, this inferred type may not
+// match value_type, and the print output may be incorrect.  In
+// practice, this is rarely a problem as for most containers
+// const_iterator is a forward iterator.  We'll fix this if there's an
+// actual need for it.  Note that this fix cannot rely on value_type
+// being defined as many user-defined container types don't have
+// value_type.

+// This header implements typed tests and type-parameterized tests.
+
+// Typed (aka type-driven) tests repeat the same test for types in a
+// list.  You must know which types you want to test with when writing
+// typed tests. Here's how you do it:
+
+#if 0
+
+// First, define a fixture class template.  It should be parameterized
+// by a type.  Remember to derive it from testing::Test.
+template <typename T>
+class FooTest : public testing::Test {
+ public:
+  ...
+  typedef std::list<T> List;
+  static T shared_;
+  T value_;
+};
+
+// Next, associate a list of types with the test case, which will be
+// repeated for each type in the list.  The typedef is necessary for
+// the macro to parse correctly.
+typedef testing::Types<char, int, unsigned int> MyTypes;
+TYPED_TEST_CASE(FooTest, MyTypes);
+
+// If the type list contains only one type, you can write that type
+// directly without Types<...>:
+//   TYPED_TEST_CASE(FooTest, int);
+
+// Then, use TYPED_TEST() instead of TEST_F() to define as many typed
+// tests for this test case as you want.
+TYPED_TEST(FooTest, DoesBlah) {
+  // Inside a test, refer to TypeParam to get the type parameter.
+  // Since we are inside a derived class template, C++ requires use to
+  // visit the members of FooTest via 'this'.
+  TypeParam n = this->value_;
+
+  // To visit static members of the fixture, add the TestFixture::
+  // prefix.
+  n += TestFixture::shared_;
+
+  // To refer to typedefs in the fixture, add the "typename
+  // TestFixture::" prefix.
+  typename TestFixture::List values;
+  values.push_back(n);
+  ...
+}
+
+TYPED_TEST(FooTest, HasPropertyA) { ... }
+
+#endif  // 0
+
+// Type-parameterized tests are abstract test patterns parameterized
+// by a type.  Compared with typed tests, type-parameterized tests
+// allow you to define the test pattern without knowing what the type
+// parameters are.  The defined pattern can be instantiated with
+// different types any number of times, in any number of translation
+// units.
+//
+// If you are designing an interface or concept, you can define a
+// suite of type-parameterized tests to verify properties that any
+// valid implementation of the interface/concept should have.  Then,
+// each implementation can easily instantiate the test suite to verify
+// that it conforms to the requirements, without having to write
+// similar tests repeatedly.  Here's an example:
+
+#if 0
+
+// First, define a fixture class template.  It should be parameterized
+// by a type.  Remember to derive it from testing::Test.
+template <typename T>
+class FooTest : public testing::Test {
+  ...
+};
+
+// Next, declare that you will define a type-parameterized test case
+// (the _P suffix is for "parameterized" or "pattern", whichever you
+// prefer):
+TYPED_TEST_CASE_P(FooTest);
+
+// Then, use TYPED_TEST_P() to define as many type-parameterized tests
+// for this type-parameterized test case as you want.
+TYPED_TEST_P(FooTest, DoesBlah) {
+  // Inside a test, refer to TypeParam to get the type parameter.
+  TypeParam n = 0;
+  ...
+}
+
+TYPED_TEST_P(FooTest, HasPropertyA) { ... }
+
+// Now the tricky part: you need to register all test patterns before
+// you can instantiate them.  The first argument of the macro is the
+// test case name; the rest are the names of the tests in this test
+// case.
+REGISTER_TYPED_TEST_CASE_P(FooTest,
+                           DoesBlah, HasPropertyA);
+
+// Finally, you are free to instantiate the pattern with the types you
+// want.  If you put the above code in a header file, you can #include
+// it in multiple C++ source files and instantiate it multiple times.
+//
+// To distinguish different instances of the pattern, the first
+// argument to the INSTANTIATE_* macro is a prefix that will be added
+// to the actual test case name.  Remember to pick unique prefixes for
+// different instances.

+// A class for indicating whether an assertion was successful.  When
+// the assertion wasn't successful, the AssertionResult object
+// remembers a non-empty message that describes how it failed.
+//
+// To create an instance of this class, use one of the factory functions
+// (AssertionSuccess() and AssertionFailure()).
+//
+// This class is useful for two purposes:
+//   1. Defining predicate functions to be used with Boolean test assertions
+//      EXPECT_TRUE/EXPECT_FALSE and their ASSERT_ counterparts
+//   2. Defining predicate-format functions to be
+//      used with predicate assertions (ASSERT_PRED_FORMAT*, etc).
+//
+// For example, if you define IsEven predicate:
+//
+//   testing::AssertionResult IsEven(int n) {
+//     if ((n % 2) == 0)
+//       return testing::AssertionSuccess();
+//     else
+//       return testing::AssertionFailure() << n << " is odd";
+//   }
+//
+// Then the failed expectation EXPECT_TRUE(IsEven(Fib(5)))
+// will print the message
+//
+//   Value of: IsEven(Fib(5))
+//     Actual: false (5 is odd)
+//   Expected: true
+//
+// instead of a more opaque
+//
+//   Value of: IsEven(Fib(5))
+//     Actual: false
+//   Expected: true
+//
+// in case IsEven is a simple Boolean predicate.
+//
+// If you expect your predicate to be reused and want to support informative
+// messages in EXPECT_FALSE and ASSERT_FALSE (negative assertions show up
+// about half as often as positive ones in our tests), supply messages for
+// both success and failure cases:
+//
+//   testing::AssertionResult IsEven(int n) {
+//     if ((n % 2) == 0)
+//       return testing::AssertionSuccess() << n << " is even";
+//     else
+//       return testing::AssertionFailure() << n << " is odd";
+//   }
+//
+// Then a statement EXPECT_FALSE(IsEven(Fib(6))) will print
+//
+//   Value of: IsEven(Fib(6))
+//     Actual: true (8 is even)
+//   Expected: false
+//
+// NB: Predicates that support negative Boolean assertions have reduced
+// performance in positive ones so be careful not to use them in tests
+// that have lots (tens of thousands) of positive Boolean assertions.
+//
+// To use this class with EXPECT_PRED_FORMAT assertions such as:
+//
+//   // Verifies that Foo() returns an even number.
+//   EXPECT_PRED_FORMAT1(IsEven, Foo());
+//
+// you need to define:
+//
+//   testing::AssertionResult IsEven(const char* expr, int n) {
+//     if ((n % 2) == 0)
+//       return testing::AssertionSuccess();
+//     else
+//       return testing::AssertionFailure()
+//         << "Expected: " << expr << " is even\n  Actual: it's " << n;
+//   }
+//
+// If Foo() returns 5, you will see the following message:
+//
+//   Expected: Foo() is even
+//     Actual: it's 5

+//                parameter iff EXPECT_DEATH compiles with it.
+//   regex     -  A regex that a macro such as EXPECT_DEATH would use to test
+//                the output of statement.  This parameter has to be
+//                compiled but not evaluated by this macro, to ensure that
+//                this macro only accepts expressions that a macro such as
+//                EXPECT_DEATH would accept.
+//   terminator - Must be an empty statement for EXPECT_DEATH_IF_SUPPORTED
+//                and a return statement for ASSERT_DEATH_IF_SUPPORTED.
+//                This ensures that ASSERT_DEATH_IF_SUPPORTED will not
+//                compile inside functions where ASSERT_DEATH doesn't
+//                compile.
+//
+//  The branch that has an always false condition is used to ensure that
+//  statement and regex are compiled (and thus syntactically correct) but
+//  never executed. The unreachable code macro protects the terminator
+//  statement from generating an 'unreachable code' warning in case

+// A "smart" pointer type with reference tracking.  Every pointer to a
+// particular object is kept on a circular linked list.  When the last pointer
+// to an object is destroyed or reassigned, the object is deleted.
+//
+// Used properly, this deletes the object when the last reference goes away.
+// There are several caveats:
+// - Like all reference counting schemes, cycles lead to leaks.
+// - Each smart pointer is actually two pointers (8 bytes instead of 4).
+// - Every time a pointer is assigned, the entire list of pointers to that
+//   object is traversed.  This class is therefore NOT SUITABLE when there
+//   will often be more than two or three pointers to a particular object.
+// - References are only tracked as long as linked_ptr<> objects are copied.
+//   If a linked_ptr<> is converted to a raw pointer and back, BAD THINGS
+//   will happen (double deletion).
+//
+// A good use of this class is storing object references in STL containers.
+// You can safely put linked_ptr<> in a vector<>.
+// Other uses may not be as good.
+//
+// Note: If you use an incomplete type with linked_ptr<>, the class
+// *containing* linked_ptr<> must have a constructor and destructor (even
+// if they do nothing!).
+//
+// Bill Gibbons suggested we use something like this.
+//
+// Thread Safety:
+//   Unlike other linked_ptr implementations, in this implementation
+//   a linked_ptr object is thread-safe in the sense that:
+//     - it's safe to copy linked_ptr objects concurrently,
+//     - it's safe to copy *from* a linked_ptr and read its underlying
+//       raw pointer (e.g. via get()) concurrently, and
+//     - it's safe to write to two linked_ptrs that point to the same
+//       shared object concurrently.
+// TODO(wan@google.com): rename this to safe_linked_ptr to avoid
+// confusion with normal linked_ptr.

+// Environment-describing macros
+// -----------------------------
+//
+// Google Test can be used in many different environments.  Macros in
+// this section tell Google Test what kind of environment it is being
+// used in, such that Google Test can provide environment-specific
+// features and implementations.
+//
+// Google Test tries to automatically detect the properties of its
+// environment, so users usually don't need to worry about these
+// macros.  However, the automatic detection is not perfect.
+// Sometimes it's necessary for a user to define some of the following
+// macros in the build script to override Google Test's decisions.
+//
+// If the user doesn't define a macro in the list, Google Test will
+// provide a default definition.  After this header is #included, all
+// macros in this list will be defined to either 1 or 0.
+//
+// Notes to maintainers:
+//   - Each macro here is a user-tweakable knob; do not grow the list
+//     lightly.
+//   - Use #if to key off these macros.  Don't use #ifdef or "#if
+//     defined(...)", which will not work as these macros are ALWAYS
+//     defined.
+//
+//   GTEST_HAS_CLONE          - Define it to 1/0 to indicate that clone(2)
+//                              is/isn't available.
+//   GTEST_HAS_EXCEPTIONS     - Define it to 1/0 to indicate that exceptions
+//                              are enabled.
+//   GTEST_HAS_GLOBAL_STRING  - Define it to 1/0 to indicate that ::string
+//                              is/isn't available (some systems define
+//                              ::string, which is different to std::string).
+//   GTEST_HAS_GLOBAL_WSTRING - Define it to 1/0 to indicate that ::string
+//                              is/isn't available (some systems define
+//                              ::wstring, which is different to std::wstring).
+//   GTEST_HAS_POSIX_RE       - Define it to 1/0 to indicate that POSIX regular
+//                              expressions are/aren't available.
+//   GTEST_HAS_PTHREAD        - Define it to 1/0 to indicate that <pthread.h>
+//                              is/isn't available.
+//   GTEST_HAS_RTTI           - Define it to 1/0 to indicate that RTTI is/isn't
+//                              enabled.
+//   GTEST_HAS_STD_WSTRING    - Define it to 1/0 to indicate that
+//                              std::wstring does/doesn't work (Google Test can
+//                              be used where std::wstring is unavailable).
+//   GTEST_HAS_TR1_TUPLE      - Define it to 1/0 to indicate tr1::tuple
+//                              is/isn't available.
+//   GTEST_HAS_SEH            - Define it to 1/0 to indicate whether the
+//                              compiler supports Microsoft's "Structured
+//                              Exception Handling".
+//   GTEST_HAS_STREAM_REDIRECTION
+//                            - Define it to 1/0 to indicate whether the

+//                              dup() and dup2().
+//   GTEST_USE_OWN_TR1_TUPLE  - Define it to 1/0 to indicate whether Google
+//                              Test's own tr1 tuple implementation should be
+//                              used.  Unused when the user sets
+//                              GTEST_HAS_TR1_TUPLE to 0.
+//   GTEST_LANG_CXX11         - Define it to 1/0 to indicate that Google Test
+//                              is building in C++11/C++98 mode.
+//   GTEST_LINKED_AS_SHARED_LIBRARY
+//                            - Define to 1 when compiling tests that use
+//                              Google Test as a shared library (known as
+//                              DLL on Windows).

+// googletestframework@googlegroups.com (patches for fixing them are
+// even more welcome!).
+//
+// It is possible that none of the GTEST_OS_* macros are defined.
+
+// Feature-indicating macros
+// -------------------------
+//
+// Macros indicating which Google Test features are available (a macro
+// is defined to 1 if the corresponding feature is supported;
+// otherwise UNDEFINED -- it's never defined to 0.).  Google Test
+// defines these macros automatically.  Code outside Google Test MUST
+// NOT define them.
+//
+// These macros are public so that portable tests can be written.
+// Such tests typically surround code using a feature with an #if
+// which controls that code.  For example:
+//
+// #if GTEST_HAS_DEATH_TEST
+//   EXPECT_DEATH(DoSomethingDeadly());
+// #endif
+//
+//   GTEST_HAS_COMBINE      - the Combine() function (for value-parameterized
+//                            tests)
+//   GTEST_HAS_DEATH_TEST   - death tests
+//   GTEST_HAS_PARAM_TEST   - value-parameterized tests
+//   GTEST_HAS_TYPED_TEST   - typed tests

+
+// Internal utilities
+// ------------------
+//
+// The following macros and utilities are for Google Test's INTERNAL
+// use only.  Code outside Google Test MUST NOT USE THEM DIRECTLY.
+//
+// Macros for basic C++ coding:
+//   GTEST_AMBIGUOUS_ELSE_BLOCKER_ - for disabling a gcc warning.
+//   GTEST_ATTRIBUTE_UNUSED_  - declares that a class' instances or a
+//                              variable don't have to be used.
+//   GTEST_DISALLOW_ASSIGN_   - disables operator=.
+//   GTEST_DISALLOW_COPY_AND_ASSIGN_ - disables copy ctor and operator=.
+//   GTEST_MUST_USE_RESULT_   - declares that a function's result must be used.
+//   GTEST_INTENTIONAL_CONST_COND_PUSH_ - start code section where MSVC C4127 is
+//                                        suppressed (constant conditional).
+//   GTEST_INTENTIONAL_CONST_COND_POP_  - finish code section where MSVC C4127
+//                                        is suppressed.
+//
+// C++11 feature wrappers:
+//
+//   testing::internal::move  - portability wrapper for std::move.
+//
+// Synchronization:
+//   Mutex, MutexLock, ThreadLocal, GetThreadCount()
+//                            - synchronization primitives.
+//
+// Template meta programming:
+//   is_pointer     - as in TR1; needed on Symbian and IBM XL C/C++ only.
+//   IteratorTraits - partial implementation of std::iterator_traits, which
+//                    is not available in libCstd when compiled with Sun C++.
+//
+// Smart pointers:
+//   scoped_ptr     - as in TR2.
+//
+// Regular expressions:
+//   RE             - a simple regular expression class using the POSIX
+//                    Extended Regular Expression syntax on UNIX-like
+//                    platforms, or a reduced regular exception syntax on
+//                    other platforms, including Windows.
+//
+// Logging:
+//   GTEST_LOG_()   - logs messages at the specified severity level.
+//   LogToStderr()  - directs all log messages to stderr.
+//   FlushInfoLog() - flushes informational log messages.
+//
+// Stdout and stderr capturing:
+//   CaptureStdout()     - starts capturing stdout.
+//   GetCapturedStdout() - stops capturing stdout and returns the captured
+//                         string.
+//   CaptureStderr()     - starts capturing stderr.
+//   GetCapturedStderr() - stops capturing stderr and returns the captured
+//                         string.
+//
+// Integer types:
+//   TypeWithSize   - maps an integer to a int type.
+//   Int32, UInt32, Int64, UInt64, TimeInMillis
+//                  - integers of known sizes.
+//   BiggestInt     - the biggest signed integer type.
+//
+// Command-line utilities:
+//   GTEST_DECLARE_*()  - declares a flag.
+//   GTEST_DEFINE_*()   - defines a flag.
+//   GetInjectableArgvs() - returns the command line as a vector of strings.
+//
+// Environment variable utilities:
+//   GetEnv()             - gets the value of an environment variable.
+//   BoolFromGTestEnv()   - parses a bool environment variable.
+//   Int32FromGTestEnv()  - parses an Int32 environment variable.
+//   StringFromGTestEnv() - parses a string environment variable.

+//   elements (and thus is invalid) when the expression is false.
+//
+// - The simpler definition
+//
+//    #define GTEST_COMPILE_ASSERT_(expr, msg) typedef char msg[(expr) ? 1 : -1]
+//
+//   does not work, as gcc supports variable-length arrays whose sizes
+//   are determined at run-time (this is gcc's extension and not part
+//   of the C++ standard).  As a result, gcc fails to reject the
+//   following code with the simple definition:
+//
+//     int foo;
+//     GTEST_COMPILE_ASSERT_(foo, msg); // not supposed to compile as foo is
+//                                      // not a compile-time constant.
+//
+// - By using the type CompileAssert<(bool(expr))>, we ensures that
+//   expr is a compile-time constant.  (Template arguments must be
+//   determined at compile-time.)
+//
+// - The outter parentheses in CompileAssert<(bool(expr))> are necessary
+//   to work around a bug in gcc 3.4.4 and 4.0.1.  If we had written
+//
+//     CompileAssert<bool(expr)>
+//
+//   instead, these compilers will refuse to compile
+//
+//     GTEST_COMPILE_ASSERT_(5 > 0, some_message);
+//
+//   (They seem to think the ">" in "5 > 0" marks the end of the
+//   template argument list.)
+//
+// - The array size is (bool(expr) ? 1 : -1), instead of simply
+//
+//     ((expr) ? 1 : -1).

+// instead of an argument type convertable to a target type.
+//
+// The syntax for using ImplicitCast_ is the same as for static_cast:

+// how do you know the pointer is really of type SubclassOfFoo?  It
+// could be a bare Foo, or of type DifferentSubclassOfFoo.  Thus,
+// when you downcast, you should use this macro.  In debug mode, we

+// 1. The parent creates a communication pipe and stores handles to both
+//    ends of it.
+// 2. The parent starts the child and provides it with the information
+//    necessary to acquire the handle to the write end of the pipe.
+// 3. The child acquires the write end of the pipe and signals the parent
+//    using a Windows event.
+// 4. Now the parent can release the write end of the pipe on its side. If
+//    this is done before step 3, the object's reference count goes down to
+//    0 and it is destroyed, preventing the child from acquiring it. The
+//    parent now has to release it, or read operations on the read end of
+//    the pipe will not return when the child terminates.
+// 5. The parent reads child's output through the pipe (outcome code and
+//    any possible error messages) from the pipe, and its stderr and then
+//    determines whether to fail the test.

+// Note: to distinguish Win32 API calls from the local method and function

+Description:
+libyuv is an open source project that includes YUV conversion and scaling
+functionality.
+
+The optimized scaler in libyuv is used in multiple resolution encoder example,
+which down-samples the original input video (f.g. 1280x720) a number of times
+in order to encode multiple resolution bit streams.

+; This is a header file for the x264ASM assembly language, which uses
+; NASM/YASM syntax combined with a large number of macros to provide easy
+; abstraction between different calling conventions (x86_32, win64, linux64).
+; It also has various other useful features to simplify writing the kind of
+; DSP functions that are most often used in x264.
+
+; Unlike the rest of x264, this file is available under an ISC license, as it
+; has significant usefulness outside of x264 and we want it to be available
+; to the largest audience possible.  Of course, if you modify it for your own
+; purposes to add a new feature, we strongly encourage contributing a patch
+; as this feature might be useful for others as well.  Send patches or ideas
+; to x264-devel@videolan.org .

+; %4 = list of names to define to registers
+; PROLOGUE can also be invoked by adding the same options to cglobal
+
+; e.g.
+; cglobal foo, 2,3,0, dst, src, tmp
+; declares a function (foo), taking two args (dst and src) and one local variable (tmp)

+; REP_RET:
+; Same, but if it doesn't pop anything it becomes a 2-byte ret, for athlons
+; which are slow when a normal ret follows a branch.
+
+; registers:
+; rN and rNq are the native-size register holding function argument N
+; rNd, rNw, rNb are dword, word, and byte size

+Description:
+x264/libav's framework for x86 assembly. Contains a variety of macros and
+defines that help automatically allow assembly to work cross-platform.
+
+Local Modifications:
+Get configuration from aom_config.asm.
+Prefix functions with aom by default.
+Manage name mangling (prefixing with '_') manually because 'PREFIX' does not
+  exist in libaom.
+Expand PIC default to macho64 and respect CONFIG_PIC from libaom
+Set 'private_extern' visibility for macho targets.
+Copy PIC 'GLOBAL' macros from x86_abi_support.asm
+Use .text instead of .rodata on macho to avoid broken tables in PIC mode.
+Use .text with no alignment for aout
+Only use 'hidden' visibility with Chromium

+; This is a header file for the x264ASM assembly language, which uses
+; NASM/YASM syntax combined with a large number of macros to provide easy
+; abstraction between different calling conventions (x86_32, win64, linux64).
+; It also has various other useful features to simplify writing the kind of
+; DSP functions that are most often used in x264.
+
+; Unlike the rest of x264, this file is available under an ISC license, as it
+; has significant usefulness outside of x264 and we want it to be available
+; to the largest audience possible.  Of course, if you modify it for your own
+; purposes to add a new feature, we strongly encourage contributing a patch
+; as this feature might be useful for others as well.  Send patches or ideas
+; to x264-devel@videolan.org .

+; Macros to eliminate most code duplication between x86_32 and x86_64:
+; Currently this works only for leaf functions which load all their arguments
+; into registers at the start, and make no other use of the stack. Luckily that
+; covers most of x264's asm.
+
+; PROLOGUE:
+; %1 = number of arguments. loads them from stack if needed.
+; %2 = number of registers used. pushes callee-saved regs if needed.
+; %3 = number of xmm registers used. pushes callee-saved xmm regs if needed.
+; %4 = (optional) stack size to be allocated. The stack will be aligned before
+;      allocating the specified stack size. If the required stack alignment is
+;      larger than the known stack alignment the stack will be manually aligned
+;      and an extra register will be allocated to hold the original stack
+;      pointer (to not invalidate r0m etc.). To prevent the use of an extra
+;      register as stack pointer, request a negative stack size.
+; %4+/%5+ = list of names to define to registers
+; PROLOGUE can also be invoked by adding the same options to cglobal
+
+; e.g.
+; cglobal foo, 2,3,7,0x40, dst, src, tmp
+; declares a function (foo) that automatically loads two arguments (dst and
+; src) into registers, uses one additional register (tmp) plus 7 vector
+; registers (m0-m6) and allocates 0x40 bytes of stack space.
+
+; TODO Some functions can use some args directly from the stack. If they're the
+; last args then you can just not declare them, but if they're in the middle
+; we need more flexible macro.
+
+; RET:
+; Pops anything that was pushed by PROLOGUE, and returns.
+
+; REP_RET:
+; Use this instead of RET if it's a branch target.
+
+; registers:
+; rN and rNq are the native-size register holding function argument N
+; rNd, rNw, rNb are dword, word, and byte size
+; rNh is the high 8 bits of the word size
+; rNm is the original location of arg N (a register or on the stack), dword
+; rNmp is native size

+// A binary executable aom_entropy_optimizer will be generated in tools/. It
+// parses a binary file consisting of counts written in the format of
+// FRAME_COUNTS in entropymode.h, and computes optimized probability tables
+// and CDF tables, which will be written to a new c file optimized_probs.c
+// according to format in the codebase.
+//
+// Command line: ./aom_entropy_optimizer [directory of the count file]
+//
+// The input file can either be generated by encoding a single clip by
+// turning on entropy_stats experiment, or be collected at a larger scale at
+// which a python script which will be provided soon can be used to aggregate
+// multiple stats output.

+The goal of this script is to identify places in the code that *may*
+be in non-compliance with google style.  It does not attempt to fix
+up these problems -- the point is to educate.  It does also not
+attempt to find all problems, or to ensure that everything it does
+find is legitimately a problem.
+
+In particular, we can get very confused by /* and // inside strings!
+We do a small hack, which is to ignore //'s with "'s after them on the
+same line, but it is far from perfect (in either direction).

+Syntax: cpplint.py [--verbose=#] [--output=vs7] [--filter=-x,+y,...]
+                   [--counting=total|toplevel|detailed] [--root=subdir]
+                   [--linelength=digits]
+        <file> [file] ...
+
+  The style guidelines this tries to follow are those in
+    http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml
+
+  Every problem is given a confidence score from 1-5, with 5 meaning we are
+  certain of the problem, and 1 meaning it could be a legitimate construct.
+  This will miss some errors, and is not a substitute for a code review.
+
+  To suppress false-positive errors of a certain category, add a
+  'NOLINT(category)' comment to the line.  NOLINT or NOLINT(*)
+  suppresses errors of all categories on that line.
+
+  The files passed in will be linted; at least one file must be provided.
+  Default linted extensions are .cc, .cpp, .cu, .cuh and .h.  Change the
+  extensions with the --extensions flag.
+
+  Flags:
+
+    output=vs7
+      By default, the output is formatted to ease emacs parsing.  Visual Studio
+      compatible output (vs7) may also be used.  Other formats are unsupported.
+
+    verbose=#
+      Specify a number 0-5 to restrict errors to certain verbosity levels.
+
+    filter=-x,+y,...
+      Specify a comma-separated list of category-filters to apply: only
+      error messages whose category names pass the filters will be printed.
+      (Category names are printed with the message and look like
+      "[whitespace/indent]".)  Filters are evaluated left to right.
+      "-FOO" and "FOO" means "do not print categories that start with FOO".
+      "+FOO" means "do print categories that start with FOO".
+
+      Examples: --filter=-whitespace,+whitespace/braces
+                --filter=whitespace,runtime/printf,+runtime/printf_format
+                --filter=-,+build/include_what_you_use
+
+      To see a list of all the categories used in cpplint, pass no arg:
+         --filter=
+
+    counting=total|toplevel|detailed
+      The total number of errors found is always printed. If
+      'toplevel' is provided, then the count of errors in each of
+      the top-level categories like 'build' and 'whitespace' will
+      also be printed. If 'detailed' is provided, then a count
+      is provided for each category like 'build/class'.
+
+    root=subdir
+      The root directory used for deriving header guard CPP variable.
+      By default, the header guard CPP variable is calculated as the relative
+      path to the directory that contains .git, .hg, or .svn.  When this flag
+      is specified, the relative path is calculated from the specified
+      directory. If the specified directory does not exist, this flag is
+      ignored.
+
+      Examples:
+        Assuing that src/.git exists, the header guard CPP variables for
+        src/chrome/browser/ui/browser.h are:
+
+        No flag => CHROME_BROWSER_UI_BROWSER_H_
+        --root=chrome => BROWSER_UI_BROWSER_H_
+        --root=chrome/browser => UI_BROWSER_H_
+
+    linelength=digits
+      This is the allowed line length for the project. The default value is
+      80 characters.
+
+      Examples:
+        --linelength=120
+
+    extensions=extension,extension,...
+      The allowed file extensions that cpplint will check
+
+      Examples:
+        --extensions=hpp,cpp

+/*!\page usage Usage
+
+    The aom multi-format codec SDK provides a unified interface amongst its
+    supported codecs. This abstraction allows applications using this SDK to
+    easily support multiple video formats with minimal code duplication or
+    "special casing." This section describes the interface common to all codecs.
+    For codec-specific details, see the \ref codecs page.
+
+    The following sections are common to all codecs:
+    - \ref usage_types
+    - \ref usage_features
+    - \ref usage_init
+    - \ref usage_errors
+
+    For more information on decoder and encoder specific usage, see the
+    following pages:
+    \if decoder
+    \li \subpage usage_decode
+    \endif
+    \if encoder
+    \li \subpage usage_encode
+    \endif
+
+    \section usage_types Important Data Types
+    There are two important data structures to consider in this interface.
+
+    \subsection usage_ctxs Contexts
+    A context is a storage area allocated by the calling application that the
+    codec may write into to store details about a single instance of that codec.
+    Most of the context is implementation specific, and thus opaque to the
+    application. The context structure as seen by the application is of fixed
+    size, and thus can be allocated with automatic storage or dynamically
+    on the heap.
+
+    Most operations require an initialized codec context. Codec context
+    instances are codec specific. That is, the codec to be used for the encoded
+    video must be known at initialization time. See #aom_codec_ctx_t for further
+    information.
+
+    \subsection usage_ifaces Interfaces
+    A codec interface is an opaque structure that controls how function calls
+    into the generic interface are dispatched to their codec-specific
+    implementations. Applications \ref MUSTNOT attempt to examine or override
+    this storage, as it contains internal implementation details likely to
+    change from release to release.
+
+    Each supported codec will expose an interface structure to the application
+    as an <code>extern</code> reference to a structure of the incomplete type
+    #aom_codec_iface_t.
+
+    \section usage_features Features
+    Several "features" are defined that are optionally implemented by codec
+    algorithms. Indeed, the same algorithm may support different features on
+    different platforms. The purpose of defining these features is that when
+    they are implemented, they conform to a common interface. The features, or
+    capabilities, of an algorithm can be queried from it's interface by using
+    the aom_codec_get_caps() method. Attempts to invoke features not supported
+    by an algorithm will generally result in #AOM_CODEC_INCAPABLE.
+
+    \if decoder
+    Currently defined decoder features include:
+    - \ref usage_cb
+    \endif
+
+    \section usage_init Initialization
+    To initialize a codec instance, the address of the codec context
+    and interface structures are passed to an initialization function. Depending
+    on the \ref usage_features that the codec supports, the codec could be
+    initialized in different modes.
+
+    To prevent cases of confusion where the ABI of the library changes,
+    the ABI is versioned. The ABI version number must be passed at
+    initialization time to ensure the application is using a header file that
+    matches the library. The current ABI version number is stored in the
+    preprocessor macros #AOM_CODEC_ABI_VERSION, #AOM_ENCODER_ABI_VERSION, and
+    #AOM_DECODER_ABI_VERSION. For convenience, each initialization function has
+    a wrapper macro that inserts the correct version number. These macros are
+    named like the initialization methods, but without the _ver suffix.
+
+
+    The available initialization methods are:
+    \if encoder
+    \li #aom_codec_enc_init (calls aom_codec_enc_init_ver())
+    \li #aom_codec_enc_init_multi (calls aom_codec_enc_init_multi_ver())
+    \endif
+    \if decoder
+    \li #aom_codec_dec_init (calls aom_codec_dec_init_ver())
+    \endif
+
+
+    \section usage_errors Error Handling
+    Almost all codec functions return an error status of type #aom_codec_err_t.
+    The semantics of how each error condition should be processed is clearly
+    defined in the definitions of each enumerated value. Error values can be
+    converted into ASCII strings with the aom_codec_error() and
+    aom_codec_err_to_string() methods. The difference between these two methods is
+    that aom_codec_error() returns the error state from an initialized context,
+    whereas aom_codec_err_to_string() can be used in cases where an error occurs
+    outside any context. The enumerated value returned from the last call can be
+    retrieved from the <code>err</code> member of the decoder context as well.
+    Finally, more detailed error information may be able to be obtained by using
+    the aom_codec_error_detail() method. Not all errors produce detailed error
+    information.
+
+    In addition to error information, the codec library's build configuration
+    is available at runtime on some platforms. This information can be returned
+    by calling aom_codec_build_config(), and is formatted as a base64 coded string
+    (comprised of characters in the set [a-z_a-Z0-9+/]). This information is not
+    useful to an application at runtime, but may be of use to aom for support.

+/*! \page usage_decode Decoding
+
+    The aom_codec_decode() function is at the core of the decode loop. It
+    processes packets of compressed data passed by the application, producing
+    decoded images. The decoder expects packets to comprise exactly one image
+    frame of data. Packets \ref MUST be passed in decode order. If the
+    application wishes to associate some data with the frame, the
+    <code>user_priv</code> member may be set.
+
+    \ref samples
+
+
+    \section usage_cb Callback Based Decoding
+    There are two methods for the application to access decoded frame data. Some
+    codecs support asynchronous (callback-based) decoding \ref usage_features
+    that allow the application to register a callback to be invoked by the
+    decoder when decoded data becomes available. Decoders are not required to
+    support this feature, however. Like all \ref usage_features, support can be
+    determined by calling aom_codec_get_caps(). Callbacks are available in both
+    frame-based and slice-based variants. Frame based callbacks conform to the
+    signature of #aom_codec_put_frame_cb_fn_t and are invoked once the entire
+    frame has been decoded. Slice based callbacks conform to the signature of
+    #aom_codec_put_slice_cb_fn_t and are invoked after a subsection of the frame
+    is decoded. For example, a slice callback could be issued for each
+    macroblock row. However, the number and size of slices to return is
+    implementation specific. Also, the image data passed in a slice callback is
+    not necessarily in the same memory segment as the data will be when it is
+    assembled into a full frame. For this reason, the application \ref MUST
+    examine the rectangles that describe what data is valid to access and what
+    data has been updated in this call. For all their additional complexity,
+    slice based decoding callbacks provide substantial speed gains to the
+    overall application in some cases, due to improved cache behavior.
+
+
+    \section usage_frame_iter Frame Iterator Based Decoding
+    If the codec does not support callback based decoding, or the application
+    chooses not to make use of that feature, decoded frames are made available
+    through the aom_codec_get_frame() iterator. The application initializes the
+    iterator storage (of type #aom_codec_iter_t) to NULL, then calls
+    aom_codec_get_frame repeatedly until it returns NULL, indicating that all
+    images have been returned. This process may result in zero, one, or many
+    frames that are ready for display, depending on the codec.
+
+
+    \section usage_postproc Postprocessing
+    Postprocessing is a process that is applied after a frame is decoded to
+    enhance the image's appearance by removing artifacts introduced in the
+    compression process. It is not required to properly decode the frame, and
+    is generally done only when there is enough spare CPU time to execute
+    the required filters. Codecs may support a number of different
+    postprocessing filters, and the available filters may differ from platform
+    to platform. Embedded devices often do not have enough CPU to implement
+    postprocessing in software. The filter selection is generally handled
+    automatically by the codec.
