-
-  - Bug Fixes:
-      This release represents approximately a year of engineering effort,
-      and contains multiple bug fixes. Please refer to git history for details.
-
-
-2012-12-21 v1.2.0
-  This release acts as a checkpoint for a large amount of internal refactoring
-  and testing. It also contains a number of small bugfixes, so all users 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.
-
-  - Enhancements:
-      VP8 optimizations for MIPS dspr2
-      vpxenc: add -quiet option
-

-
-  - Bug Fixes:
-      Fixes multithreaded encoder race condition in loopfilter
-      Fixes multi-resolution threaded encoding
-      Fix potential encoder dead-lock after picture resize
-
-
-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
-          Runtime detection of available processor cores.
-          Allow specifying --end-usage by enum name
-          vpxdec: test for frame corruption
-          vpxenc: add quantizer histogram display
-          vpxenc: add rate histogram display
-          Set VPX_FRAME_IS_DROPPABLE
-          update configure for ios sdk 4.3
-          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.
-
-          Reduce motion vector search on alt-ref frame.
-          Encoder loopfilter running in its own thread
-          Reworked loopfilter to precalculate more parameters

-          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. 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

-
-
-2011-03-07 v0.9.6 "Bali"
-  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.
-
-  - Enhancements:

-      --tune=ssim option to enable activity masking
-      improved postproc visualizations for development
-      updated support for Apple iOS to SDK 4.2
-      query decoder to determine which reference frames were updated
-      implemented error tracking in the decoder
-      fix pipe support on windows
-
-  - 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.
-
-        Improved encoder threading
-        Dont pick encoder filter level when loopfilter is disabled.

-      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

-
-
-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
-
