127 is over, the old "timeout" option will be removed, and "stimeout" will be
128 renamed to "stimeout" (the "timeout" option will essentially change semantics).
130 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h

144 Explicitly make avformat_network_init() and avformat_network_deinit() optional.
145 If these are not called, network initialization and deinitialization is
146 automatic, and unlike in older versions, fully supported, unless libavformat

154 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
156 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
157 Deprecate the entire library. Merged years ago to provide compatibility
158 with Libav, it remained unmaintained by the FFmpeg project and duplicated
159 functionality provided by libswresample.

162 Users of this library are asked to migrate to libswresample, which, as well as
163 providing more functionality, is faster and has higher accuracy.
165 2017-12-26 - a04c2c707d - lavc 58.9.100 - avcodec.h
166 Deprecate av_lockmgr_register(). You need to build FFmpeg with threading

224 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
225 (avcodec_send_packet/avcodec_receive_frame) always work with reference
228 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
229 Add av_color_range_from_name(), av_color_primaries_from_name(),

265 DXVA2 and D3D11 hardware accelerated decoding now supports the new hwaccel API,
266 which can create the decoder context and allocate hardware frame automatically.
267 See AVCodecContext.hw_device_ctx and AVCodecContext.hw_frames_ctx. For D3D11,
268 the new AV_PIX_FMT_D3D11 pixfmt must be used with the new API.

311 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
312 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
313 set the Cuda device handle.
315 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

339 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
340 (via an entry named "rotate"). Use av_stream_get_side_data() with
341 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with

343 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
344 to be added to the AVStream.

377 bound_bottom, padding) to AVSphericalMapping.
379 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
380 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
381 native decoder format. (The default value is not changed.)
383 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
384 Remove requirement to use AVOption or accessors to access certain fields

503 Fix accidental ABI breakage in AVFilterContext.
504 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
506 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
507 compatible with lavfi>=6.47.100. Potentially also affects other users of
508 libavfilter if they are using one of the affected fields.

574 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
575 the reset of the ASS ReadOrder field on flush. This affects the content of

579 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
580 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
581 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
582 The default value for this option will change to "ass" at the next major
583 libavcodec version bump.
585 The current default is "ass_with_timings" for compatibility. This means that
586 all subtitles text decoders currently still output ASS with timings printed
587 as strings in the AVSubtitles.rects[N]->ass fields.
589 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
590 timing is limited to a 1/100 time base, so this is relevant for any subtitles
591 format needing a bigger one), ease timing adjustments, and prevents the need
592 of removing the timing from the decoded string yourself. This form is also
593 known as "the Matroska form". The timing information (start time, duration)
594 can be found in the AVSubtitles fields.

3018 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
3019 Make avfilter_get_video_buffer() recursive and add the w and h
3022 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
3023 Add w and h fields to AVFilterPic.
3025 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3026 This is now an unsigned int instead of a signed int.
3028 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3029 Add a pts field to AVSubtitle which gives the subtitle packet pts
3030 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3031 not work right without this.
3033 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3034 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3035 major version. Use AV_PKT_FLAG_KEY instead.
3037 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3038 av_lockmgr_register() can be used to register a callback function
3039 that lavc (and in the future, libraries that depend on lavc) can use
3040 to implement mutexes. The application should provide a callback function
3041 that implements the AV_LOCK_* operations described in avcodec.h.
3042 When the lock manager is registered, FFmpeg is guaranteed to behave
3043 correctly in a multi-threaded application.
3045 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3046 av_free_packet() is no longer an inline function. It is now exported.
3048 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3049 Please use NULL instead. This has been supported since r16506
3050 (lavf > 52.23.1, lavc > 52.10.0).
3052 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3053 The old decoding functions are deprecated, all new code should use the
3054 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3055 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3056 argument instead of a const uint8_t *buf / int buf_size pair.
3058 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3059 Introduce the av_fifo_space() function.
3061 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3062 Move AVPacket declaration from libavformat/avformat.h to
3063 libavcodec/avcodec.h.
3065 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3066 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3067 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3068 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3069 PIX_FMT_BGR32_1 are now macros.
3070 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3071 Re-sort the enum PixelFormat list accordingly.
3072 This change breaks API/ABI backward compatibility.
3074 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3075 Add the enum PixelFormat values:
3076 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3077 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3079 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3080 The Mersenne Twister PRNG implemented through the av_random* functions
3081 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3084 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3085 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3086 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3087 and av_fifo_realloc2.
3088 In addition, the order of the function arguments of av_fifo_generic_read
3089 was changed to match av_fifo_generic_write.
3090 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3091 applications, they may not use sizeof() or directly access members.
3093 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3094 Introduce a new metadata API (see av_metadata_get() and friends).
3095 The old API is now deprecated and should not be used anymore. This especially
3096 includes the following structure fields:
3097 - AVFormatContext.title
3098 - AVFormatContext.author
3099 - AVFormatContext.copyright
3100 - AVFormatContext.comment
3101 - AVFormatContext.album
3102 - AVFormatContext.year
3103 - AVFormatContext.track
3104 - AVFormatContext.genre
3107 - AVProgram.provider_name
