+vpx Multi-Format Codec SDK
+README - 1 August 2013
+
+Welcome to the WebM VP8/VP9 Codec SDK!
+
+COMPILING THE APPLICATIONS/LIBRARIES:
+ The build system used is similar to autotools. Building generally consists of
+ "configuring" with your desired build options, then using GNU make to build
+ the application.
+
+ 1. Prerequisites
+
+ * All x86 targets require the Yasm[1] assembler be installed.
+ * All Windows builds require that Cygwin[2] be installed.
+ * Building the documentation requires PHP[3] and Doxygen[4]. If you do not
+ have these packages, you must pass --disable-install-docs to the
+ configure script.
+ * Downloading the data for the unit tests requires curl[5] and sha1sum.
+ sha1sum is provided via the GNU coreutils, installed by default on
+ many *nix platforms, as well as MinGW and Cygwin. If coreutils is not
+ available, a compatible version of sha1sum can be built from
+ source[6]. These requirements are optional if not running the unit
+ tests.
+
+ [1]: http://www.tortall.net/projects/yasm
+ [2]: http://www.cygwin.com
+ [3]: http://php.net
+ [4]: http://www.doxygen.org
+ [5]: http://curl.haxx.se
+ [6]: http://www.microbrew.org/tools/md5sha1sum/
+
+ 2. Out-of-tree builds
+ Out of tree builds are a supported method of building the application. For
+ an out of tree build, the source tree is kept separate from the object
+ files produced during compilation. For instance:
+
+ $ mkdir build
+ $ cd build
+ $ ../libvpx/configure <options>
+ $ make
+
+ 3. Configuration options
+ The 'configure' script supports a number of options. The --help option can be
+ used to get a list of supported options:
+ $ ../libvpx/configure --help
+
+ 4. Cross development
+ For cross development, the most notable option is the --target option. The
+ most up-to-date list of supported targets can be found at the bottom of the
+ --help output of the configure script. As of this writing, the list of
+ available targets is:

+ generic-gnu
+
+ The generic-gnu target, in conjunction with the CROSS environment variable,
+ can be used to cross compile architectures that aren't explicitly listed, if
+ the toolchain is a cross GNU (gcc/binutils) toolchain. Other POSIX toolchains
+ will likely work as well. For instance, to build using the mipsel-linux-uclibc
+ toolchain, the following command could be used (note, POSIX SH syntax, adapt
+ to your shell as necessary):
+
+ $ CROSS=mipsel-linux-uclibc- ../libvpx/configure
+
+ In addition, the executables to be invoked can be overridden by specifying the
+ environment variables: CC, AR, LD, AS, STRIP, NM. Additional flags can be
+ passed to these executables with CFLAGS, LDFLAGS, and ASFLAGS.
+
+ 5. Configuration errors
+ If the configuration step fails, the first step is to look in the error log.
+ This defaults to config.log. This should give a good indication of what went
+ wrong. If not, contact us for support.
+
+SUPPORT
+ This library is an open source project supported by its community. Please
+ please email webm-discuss@webmproject.org for help.
