In addition, it fixes a decoder bug (first introduced in - Duclair) so all users of that release are encouraged to upgrade. - - - Upgrading: - This release is ABI and API compatible with Duclair (v1.0.0). Users - of older releases should refer to the Upgrading notes in this - document for that release. - - This release introduces a new temporal denoiser, controlled by the - VP8E_SET_NOISE_SENSITIVITY control. The temporal denoiser does not - currently take a strength parameter, so the control is effectively - a boolean - zero (off) or non-zero (on). For compatibility with - existing applications, the values accepted are the same as those - for the spatial denoiser (0-6). The temporal denoiser is enabled - by default, and the older spatial denoiser may be restored by - configuring with --disable-temporal-denoising. The temporal denoiser - is more computationally intensive than the spatial one. - - This release removes support for a legacy, decode only API that was - supported, but deprecated, at the initial release of libvpx - (v0.9.0). This is not expected to have any impact. If you are - impacted, you can apply a reversion to commit 2bf8fb58 locally. - Please update to the latest libvpx API if you are affected. - - - Enhancements: - Adds a motion compensated temporal denoiser to the encoder, which - gives higher quality than the older spatial denoiser. (See above - for notes on upgrading). - - In addition, support for new compilers and platforms were added, - including: - improved support for XCode - Android x86 NDK build - OS/2 support - SunCC support - - Changing resolution with vpx_codec_enc_config_set() is now - supported. Previously, reinitializing the codec was required to - change the input resolution. - - The vpxenc application has initial support for producing multiple - encodes from the same input in one call. Resizing is not yet - supported, but varying other codec parameters is. Use -- to - delineate output streams. Options persist from one stream to the - next. - - Also, the vpxenc application will now use a keyframe interval of - 5 seconds by default. Use the --kf-max-dist option to override. - - - Speed: - Decoder performance improved 2.5% versus Duclair. Encoder speed is - consistent with Duclair for most material. Two pass encoding of - slideshow-like material will see significant improvements. - - Large realtime encoding speed gains at a small quality expense are - possible by configuring the on-the-fly bitpacking experiment with - --enable-onthefly-bitpacking. Realtime encoder can be up to 13% - faster (ARM) depending on the number of threads and bitrate - settings. This technique sees constant gain over the 5-16 speed - range. For VC style input the loss seen is up to 0.2dB. See commit - 52cf4dca for further details. - - - Quality: - On the whole, quality is consistent with the Duclair release. Some - tweaks: - - Reduced blockiness in easy sections by applying a penalty to - intra modes. - - Improved quality of static sections (like slideshows) with - two pass encoding. - - Improved keyframe sizing with multiple temporal layers - - - Bug Fixes: - Corrected alt-ref contribution to frame rate for visible updates - to the alt-ref buffer. This affected applications making manual - usage of the frame reference flags, or temporal layers. - - Additional constraints were added to disable multi-frame quality - enhancement (MFQE) in sections of the frame where there is motion. - (#392) - - Fixed corruption issues when vpx_codec_enc_config_set() was called - with spatial resampling enabled. - - Fixed a decoder error introduced in Duclair where the segmentation - map was not being reinitialized on keyframes (#378) - - -2012-01-27 v1.0.0 "Duclair" - Our fourth named release, focused on performance and features related to - real-time encoding. It also fixes a decoder crash bug introduced in - v0.9.7, so all users of that release are encouraged to upgrade. - - - Upgrading: - This release is ABI incompatible with prior releases of libvpx, so the - "major" version number has been bumped to 1. You must recompile your - applications against the latest version of the libvpx headers. The - API remains compatible, and this should not require code changes in most - applications. - - - Enhancements: - This release introduces several substantial new features to the encoder, - of particular interest to real time streaming applications. - - Temporal scalability allows the encoder to produce a stream that can - be decimated to different frame rates, with independent rate targetting - for each substream. - - Multiframe quality enhancement postprocessing can make visual quality - more consistent in the presence of frames that are substantially - different quality than the surrounding frames, as in the temporal - scalability case and in some forced keyframe scenarios. - - Multiple-resolution encoding support allows the encoding of the - same content at different resolutions faster than encoding them - separately. - - - Speed: - Optimization targets for this release included the decoder and the real- - time modes of the encoder. Decoder speed on x86 has improved 10.5% with - this release. Encoder improvements followed a curve where speeds 1-3 - improved 4.0%-1.5%, speeds 4-8 improved <1%, and speeds 9-16 improved - 1.5% to 10.5%, respectively. "Best" mode speed is consistent with the - Cayuga release. - - - Quality: - Encoder quality in the single stream case is consistent with the Cayuga - release. - - - Bug Fixes: - This release fixes an OOB read decoder crash bug present in v0.9.7 - related to the clamping of motion vectors in SPLITMV blocks. This - behavior could be triggered by corrupt input or by starting - decoding from a P-frame. - - -2011-08-15 v0.9.7-p1 "Cayuga" patch 1 - This is an incremental bugfix release against Cayuga. All users of that - release are strongly encouraged to upgrade. - - - Fix potential OOB reads (cdae03a) - - An unbounded out of bounds read was discovered when the - decoder was requested to perform error concealment (new in - Cayuga) given a frame with corrupt partition sizes. - - A bounded out of bounds read was discovered affecting all - versions of libvpx. Given an multipartition input frame that - is truncated between the mode/mv partition and the first - residiual paritition (in the block of partition offsets), up - to 3 extra bytes could have been read from the source buffer. - The code will not take any action regardless of the contents - of these undefined bytes, as the truncated buffer is detected - immediately following the read based on the calculated - starting position of the coefficient partition. - - - Fix potential error concealment crash when the very first frame - is missing or corrupt (a609be5) - - - Fix significant artifacts in error concealment (a4c2211, 99d870a) - - - Revert 1-pass CBR rate control changes (e961317) - Further testing showed this change produced undesirable visual - artifacts, rolling back for now. - - -2011-08-02 v0.9.7 "Cayuga" - Our third named release, focused on a faster, higher quality, encoder. - - - Upgrading: - This release is backwards compatible with Aylesbury (v0.9.5) and - Bali (v0.9.6).

On x86, these measure at approximately 11.5% in Best mode, - 21.5% in Good mode (speed 0), and 22.5% in Realtime mode (speed 6). - On ARM Cortex A9 with Neon extensions, real-time encoding of video - telephony content is 35% faster than Bali on single core and 48% - faster on multi-core. On the NVidia Tegra2 platform, real time - encoding is 40% faster than Bali. - - Decoder speed was not a priority for this release, but improved - approximately 8.4% on x86. - - Reduce motion vector search on alt-ref frame. - Encoder loopfilter running in its own thread - Reworked loopfilter to precalculate more parameters - SSE2/SSSE3 optimizations for build_predictors_mbuv{,_s}(). - Make hor UV predict ~2x faster (73 vs 132 cycles) using SSSE3. - Removed redundant checks - Reduced structure sizes - utilize preload in ARMv6 MC/LPF/Copy routines - ARM optimized quantization, dfct, variance, subtract - Increase chrow row alignment to 16 bytes. - disable trellis optimization for first pass - Write SSSE3 sub-pixel filter function - Improve SSE2 half-pixel filter funtions - Add vp8_sub_pixel_variance16x8_ssse3 function - Reduce unnecessary distortion computation - Use diamond search to replace full search - Preload reference area in sub-pixel motion search (real-time mode) - - - Quality: - This release focused primarily on one-pass use cases, including - video conferencing.
