| 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. | |
| - Enhancements: | |

| 2012-05-09 v1.1.0 "Eider" | |
| This introduces a number of enhancements, mostly focused on real-time | |
| encoding. 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). Users of older releases should refer to the Upgrading | |
| notes in this document for that release. | |
| - Enhancements: | |

| New ways of passing encoded data between encoder and decoder. | |
| - Speed: | |
| This release includes across-the-board speed improvements to the | |
| encoder. 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. | |

| Preload reference area in sub-pixel motion search (real-time mode) | |
| - Quality: | |
| This release focused primarily on one-pass use cases, including | |
| video conferencing. Low latency data rate control was significantly | |
| improved, improving streamability over bandwidth constrained links. | |
| Added support for error concealment, allowing frames to maintain | |
| visual quality in the presence of substantial packet loss. | |
| Add rc_max_intra_bitrate_pct control | |

| Our second named release, focused on a faster, higher quality, encoder. | |
| - Upgrading: | |
| This release is backwards compatible with Aylesbury (v0.9.5). Users | |
| of older releases should refer to the Upgrading notes in this | |
| document for that release. | |

| on x86 about 40%, up to 100% on user-generated content at that speed. | |
| Best quality mode speed improved 35%, and realtime speed 10-20%. This | |
| release also saw significant improvement in realtime encoding speed | |
| on ARM platforms. | |

| also includes support for "activity masking," which greatly improves | |
| SSIM at the expense of PSNR. For now, this feature is available with | |
| the --tune=ssim option. Further experimentation in this area | |
| is ongoing. This release also introduces a new rate control mode | |
| called "CQ," which changes the allocation of bits within a clip to | |
| the sections where they will have the most visual impact. | |
| Tuning for the more exact quantizer. | |
| Relax rate control for last few frames | |

| Our first named release, focused on a faster decoder, and a better encoder. | |
| - Upgrading: | |
| This release incorporates backwards-incompatible changes to the | |
| ivfenc and ivfdec tools. These tools are now called vpxenc and vpxdec. | |
| vpxdec | |
| * the -q (quiet) option has been removed, and replaced with | |
| -v (verbose). the output is quiet by default. Use -v to see | |
| the version number of the binary. | |
| * The default behavior is now to write output to a single file | |
| instead of individual frames. The -y option has been removed. | |
| Y4M output is the default. | |
| * For raw I420/YV12 output instead of Y4M, the --i420 or --yv12 | |
| options must be specified. | |
| $ ivfdec -o OUTPUT INPUT | |
| $ vpxdec --i420 -o OUTPUT INPUT | |
| * If an output file is not specified, the default is to write | |
| Y4M to stdout. This makes piping more natural. | |
| $ ivfdec -y -o - INPUT | ... | |
| $ vpxdec INPUT | ... | |
| * The output file has additional flexibility for formatting the | |
| filename. It supports escape characters for constructing a | |
| filename from the width, height, and sequence number. This | |
| replaces the -p option. To get the equivalent: | |
| $ ivfdec -p frame INPUT | |
| $ vpxdec --i420 -o frame-%wx%h-%4.i420 INPUT | |
| vpxenc | |
| * The output file must be specified with -o, rather than as the | |
| last argument. | |
| $ ivfenc <options> INPUT OUTPUT | |
| $ vpxenc <options> -o OUTPUT INPUT | |
| * The output defaults to webm. To get IVF output, use the --ivf | |
| option. | |
| $ ivfenc <options> INPUT OUTPUT.ivf | |
| $ vpxenc <options> -o OUTPUT.ivf --ivf INPUT | |
| - Enhancements: | |
| ivfenc and ivfdec have been renamed to vpxenc, vpxdec. | |
