+              │ RELEASE NOTES for FFmpeg 2.6 "Grothendieck" │
+              └─────────────────────────────────────────────┘
+
+   The FFmpeg Project proudly presents FFmpeg 2.6 "Grothendieck", about 3
+   months after the release of FFmpeg 2.5.
+
+   A lot of important work got in this time, so let's start talking about what
+   we like to brag the most about: features.
+
+   A lot of people will probably be happy to hear that we now have support for
+   NVENC — the Nvidia Video Encoder interface for H.264 encoding — thanks to
+   Timo Rothenpieler, with some little help from NVIDIA and Philip Langdale.
+
+   People in the broadcasting industry might also be interested in the first
+   steps of closed captions support with the introduction of a decoder by
+   Anshul Maheswhwari.
+
+   Regarding filters love, we improved and added many. We could talk about the
+   10-bit support in spp, but maybe it's more important to mention the addition
+   of colorlevels (yet another color handling filter), tblend (allowing you
+   to for example run a diff between successive frames of a video stream), or
+   the dcshift audio filter.
+
+   There are also two other important filters landing in libavfilter: palettegen
+   and paletteuse. Both submitted by the Stupeflix company. These filters will
+   be very useful in case you are looking for creating high quality GIFs, a
+   format that still bravely fights annihilation in 2015.
+
+   There are many other new features, but let's follow-up on one big cleanup
+   achievement: the libmpcodecs (MPlayer filters) wrapper is finally dead. The
+   last remaining filters (softpulldown/repeatfields, eq*, and various
+   postprocessing filters) were ported by Arwa Arif (OPW student) and Paul B
+   Mahol.
+
+   Concerning API changes, there are not many things to mention. Though, the
+   introduction of device inputs and outputs listing by Lukasz Marek is a
+   notable addition (try ffmpeg -sources or ffmpeg -sinks for an example of
+   the usage). As usual, see doc/APIchanges for more information.
+
+   Now let's talk about optimizations. Ronald S. Bultje made the VP9 decoder
+   usable on x86 32-bit systems and pre-ssse3 CPUs like Phenom (even dual core
+   Athlons can play 1080p 30fps VP9 content now), so we now secretly hope for
+   Google and Mozilla to use ffvp9 instead of libvpx. But VP9 is not the
+   center of attention anymore, and HEVC/H.265 is also getting many
+   improvements, which include C and x86 ASM optimizations, mainly from James
+   Almer, Christophe Gisquet and Pierre-Edouard Lepere.
+
+   Even though we had many x86 contributions, it is not the only architecture
+   getting some love, with Seppo Tomperi adding ARM NEON optimizations to the
+   HEVC stack, and James Cowgill adding MIPS64 assembly for all kind of audio
+   processing code in libavcodec.
+
+   And finally, Michael Niedermayer is still fixing many bugs, dealing with
+   most of the boring work such as making releases, applying tons of
+   contributors patches, and daily merging the changes from the Libav project.
+
+   A more complete Changelog is available at the root of the project, and the
+   complete Git history on http://source.ffmpeg.org.
+
+   We hope you will like this release as much as we enjoyed working on it, and
+   as usual, if you have any questions about it, or any FFmpeg related topic,
+   feel free to join us on the #ffmpeg IRC channel (on irc.freenode.net) or ask
+   on the mailing-lists.

 API changes, most recent first:
 
-2017-03-31 - xxxxxxx - lavu 55.57.100 - spherical.h
-  Add av_spherical_projection_name().
-  Add av_spherical_from_name().
-
-2017-03-30 - xxxxxxx - lavu 55.53.100 / 55.27.0 - hwcontext.h
-  Add av_hwframe_map() and associated AV_HWFRAME_MAP_* flags.
-  Add av_hwframe_ctx_create_derived().
-
-2017-03-29 - bfdcdd6d82 - lavu 55.52.100 - avutil.h
-  add av_fourcc_make_string() function and av_fourcc2str() macro to replace
-  av_get_codec_tag_string() from lavc.
-
-2017-03-27 - ddef3d902f - lavf 57.68.100 - avformat.h
-  Deprecate that demuxers export the stream rotation angle in AVStream.metadata
-  (via an entry named "rotate"). Use av_stream_get_side_data() with
-  AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
-  av_display_rotation_get(). The same is done for muxing. Instead of adding a
-  "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
-  to be added to the AVStream.
-
-2017-03-23 - 7e4ba776a2 - lavc 57.85.101 - avcodec.h
-  vdpau hardware accelerated decoding now supports the new hwaccel API, which
-  can create the decoder context and allocate hardware frame automatically.
-  See AVCodecContext.hw_device_ctx and AVCodecContext.hw_frames_ctx.
-
-2017-03-23 - 156bd8278f - lavc 57.85.100 - avcodec.h
-  Add AVCodecContext.hwaccel_flags field. This will control some hwaccels at
-  a later point.
-
-2017-03-21 - xxxxxxx - lavf 57.67.100 / 57.08.0 - avio.h
-  Add AVIO_SEEKABLE_TIME flag.
-
-2017-03-21 - d682ae70b4 - lavf 57.66.105, lavc 57.83.101 - avformat.h, avcodec.h
-  Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
-  bump, and libavformat will behave as if it were always set.
-  Deprecate av_packet_merge_side_data() and av_packet_split_side_data().
-
-2016-03-20 - xxxxxxx - lavu 55.50.100 / 55.21.0 - imgutils.h
-  Add av_image_copy_uc_from(), a version of av_image_copy() for copying
-  from GPU mapped memory.
-
-2017-03-20 - 9c2436e - lavu 55.49.100 - pixdesc.h
-  Add AV_PIX_FMT_FLAG_BAYER pixel format flag.
-
-2017-03-18 - 3796fb2692 - lavfi 6.77.100 - avfilter.h
-  Deprecate AVFilterGraph.resample_lavr_opts
-  It's never been used by avfilter nor passed to anything.
-
-2017-02-10 - xxxxxxx - lavu 55.48.100 / 55.33.0 - spherical.h
-  Add AV_SPHERICAL_EQUIRECTANGULAR_TILE, av_spherical_tile_bounds(),
-  and projection-specific properties (bound_left, bound_top, bound_right,
-  bound_bottom, padding) to AVSphericalMapping.
-
-2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
-  AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
-  native decoder format. (The default value is not changed.)

-  "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
-  the reset of the ASS ReadOrder field on flush. This affects the content of
-  AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see

-
-2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
-  Add a "sub_text_format" subtitles decoding option allowing the values "ass"
-  (recommended) and "ass_with_timings" (not recommended, deprecated, default).
-  The default value for this option will change to "ass" at the next major
-  libavcodec version bump.
-
-  The current default is "ass_with_timings" for compatibility. This means that
-  all subtitles text decoders currently still output ASS with timings printed
-  as strings in the AVSubtitles.rects[N]->ass fields.
-
-  Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
-  timing is limited to a 1/100 time base, so this is relevant for any subtitles
-  format needing a bigger one), ease timing adjustments, and prevents the need
-  of removing the timing from the decoded string yourself. This form is also
-  known as "the Matroska form". The timing information (start time, duration)
-  can be found in the AVSubtitles fields.

-CONTEXT
-=======
-
-The FFmpeg project merges all the changes from the Libav project
-(https://libav.org) since the origin of the fork (around 2011).
-
-With the exceptions of some commits due to technical/political disagreements or
-issues, the changes are merged on a more or less regular schedule (daily for
-years thanks to Michael, but more sparse nowadays).
-
-WHY
-===
-
-The majority of the active developers believe the project needs to keep this
-policy for various reasons.
-
-The most important one is that we don't want our users to have to choose
-between two distributors of libraries of the exact same name in order to have a
-different set of features and bugfixes. By taking the responsibility of
-unifying the two codebases, we allow users to benefit from the changes from the
-two teams.
-
-Today, FFmpeg has a much larger user database (we are distributed by every
-major distribution), so we consider this mission a priority.
-
-A different approach to the merge could have been to pick the changes we are
-interested in and drop most of the cosmetics and other less important changes.
-Unfortunately, this makes the following picks much harder, especially since the
-Libav project is involved in various deep API changes. As a result, we decide
-to virtually take everything done there.
-
-Any Libav developer is of course welcome anytime to contribute directly to the
-FFmpeg tree. Of course, we fully understand and are forced to accept that very
-few Libav developers are interested in doing so, but we still want to recognize
-their work. This leads us to create merge commits for every single one from
-Libav. The original commit appears totally unchanged with full authorship in
-our history (and the conflict are solved in the merge one). That way, not a
-single thing from Libav will be lost in the future in case some reunification
-happens, or that project disappears one way or another.
-
-DOWNSIDES
-=========
-
-Of course, there are many downsides to this approach.
-
-- It causes a non negligible merge commits pollution. We make sure there are
-  not several level of merges entangled (we do a 1:1 merge/commit), but it's
-  still a non-linear history.
-
-- Many duplicated work. For instance, we added libavresample in our tree to
-  keep compatibility with Libav when our libswresample was already covering the
-  exact same purpose. The same thing happened for various elements such as the
-  ProRes support (but differences in features, bugs, licenses, ...). There are
-  many work to do to unify them, and any help is very much welcome.
-
-- So much manpower from both FFmpeg and Libav is lost because of this mess. We
-  know it, and we don't know how to fix it. It takes incredible time to do
-  these merges, so we have even less time to work on things we personally care
-  about. The bad vibes also do not help with keeping our developers motivated.
-
-- There is a growing technical risk factor with the merges due to the codebase
-  differing more and more.
-
-MERGE GUIDELINES
-================
-
-The following gives developer guidelines on how to proceed when merging Libav commits.
-
-Before starting, you can reduce the risk of errors on merge conflicts by using
-a different merge conflict style:
-
-    $ git config --global merge.conflictstyle diff3
-
-tools/libav-merge-next-commit is a script to help merging the next commit in
-the queue. It assumes a remote named libav. It has two modes: merge, and noop.
-The noop mode creates a merge with no change to the HEAD. You can pass a hash
-as extra argument to reference a justification (it is common that we already
-have the change done in FFmpeg).
-
-Also see tools/murge, you can copy and paste a 3 way conflict into its stdin
-and it will display colored diffs. Any arguments to murge (like ones to suppress
-whitespace differences) are passed into colordiff.
-
-TODO/FIXME/UNMERGED
-===================
-
-Stuff that didn't reach the codebase:
--------------------------------------
-
-- HEVC DSP and x86 MC SIMD improvements from Libav (see https://ffmpeg.org/pipermail/ffmpeg-devel/2015-December/184777.html)
-  - 1f821750f hevcdsp: split the qpel functions by width instead of by the subpixel fraction
-  - 818bfe7f0 hevcdsp: split the epel functions by width
-  - 688417399 hevcdsp: split the pred functions by width
-  - a853388d2 hevc: change the stride of the MC buffer to be in bytes instead of elements
-  - 0cef06df0 checkasm: add HEVC MC tests
-  - e7078e842 hevcdsp: add x86 SIMD for MC
-- VAAPI VP8 decode hwaccel (currently under review: http://ffmpeg.org/pipermail/ffmpeg-devel/2017-February/thread.html#207348)
-- Removal of the custom atomic API (5cc0057f49, see http://ffmpeg.org/pipermail/ffmpeg-devel/2017-March/209003.html)
-- Use the new bitstream filter for extracting extradata (8e2ea69135 and 096a8effa3, see https://ffmpeg.org/pipermail/ffmpeg-devel/2017-March/209068.html)
-- Read aac_adtstoasc extradata updates from packet side data on Matroska once mov and the bsf in question are fixed (See 13a211e632 and 5ef1959080)
-
-Collateral damage that needs work locally:
-------------------------------------------
-
-- Merge proresdec2.c and proresdec_lgpl.c
-- Merge proresenc_anatoliy.c and proresenc_kostya.c
-- Remove ADVANCED_PARSER in libavcodec/hevc_parser.c
-- Fix MIPS AC3 downmix
-- hlsenc encryption support may need some adjustment (see edc43c571d)
-
-Extra changes needed to be aligned with Libav:
-----------------------------------------------
-
-- Switching our examples to the new encode/decode API (see 67d28f4a0f)
-- HEVC IDCT bit depth 12-bit support (Libav added 8 and 10 but doesn't have 12)
