| |
| - 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. |
| |

| |
| |
| 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: |
| Stereo 3D format support for vpxenc |

| Avoid text relocations in ARM vp8 decoder |
| Generate a vpx.pc file for pkg-config. |
| 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. |
| |

| 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 |
| Limit size of initial keyframe in one-pass. |

| 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. |
| |

| |
| - Speed: |
| Primary focus was on good quality mode, speed 0. Average improvement |
| 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. |
| |

| |
| 2010-10-28 v0.9.5 "Aylesbury" |
| 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: |
