175 is over, the old "timeout" option will be removed, and "stimeout" will be
176 renamed to "stimeout" (the "timeout" option will essentially change semantics).
178 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h

202 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
204 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
205 Deprecate the entire library. Merged years ago to provide compatibility
206 with Libav, it remained unmaintained by the FFmpeg project and duplicated

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

387 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
388 (via an entry named "rotate"). Use av_stream_get_side_data() with
389 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
390 av_display_rotation_get(). The same is done for muxing. Instead of adding a

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

622 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing

627 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
628 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
629 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
630 The default value for this option will change to "ass" at the next major
631 libavcodec version bump.
633 The current default is "ass_with_timings" for compatibility. This means that
634 all subtitles text decoders currently still output ASS with timings printed
635 as strings in the AVSubtitles.rects[N]->ass fields.
637 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
638 timing is limited to a 1/100 time base, so this is relevant for any subtitles
639 format needing a bigger one), ease timing adjustments, and prevents the need
640 of removing the timing from the decoded string yourself. This form is also
641 known as "the Matroska form". The timing information (start time, duration)
642 can be found in the AVSubtitles fields.

3041 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
3042 Remove the next field from AVFilter, this is not anymore required.
3044 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3045 Introduce the avfilter_next() function.
3047 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3048 Change the signature of avfilter_register() to make it return an
3049 int. This is required since now the registration operation may fail.
3051 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3052 Make the pixdesc.h API public.
3054 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3059 Add a description field to AVFilter.
3061 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
3062 Change the interface of avfilter_make_format_list() from

3076 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3077 Add a pts field to AVSubtitle which gives the subtitle packet pts
3078 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3079 not work right without this.
3081 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3082 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3083 major version. Use AV_PKT_FLAG_KEY instead.
3085 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3086 av_lockmgr_register() can be used to register a callback function
3087 that lavc (and in the future, libraries that depend on lavc) can use
3088 to implement mutexes. The application should provide a callback function
3089 that implements the AV_LOCK_* operations described in avcodec.h.
3090 When the lock manager is registered, FFmpeg is guaranteed to behave
3091 correctly in a multi-threaded application.
3093 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3094 av_free_packet() is no longer an inline function. It is now exported.
3096 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3097 Please use NULL instead. This has been supported since r16506
3098 (lavf > 52.23.1, lavc > 52.10.0).
3100 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3101 The old decoding functions are deprecated, all new code should use the
3102 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3103 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3104 argument instead of a const uint8_t *buf / int buf_size pair.
3106 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3107 Introduce the av_fifo_space() function.
3109 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3110 Move AVPacket declaration from libavformat/avformat.h to
3111 libavcodec/avcodec.h.
3113 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3114 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3115 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3116 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3117 PIX_FMT_BGR32_1 are now macros.
3118 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3119 Re-sort the enum PixelFormat list accordingly.
3120 This change breaks API/ABI backward compatibility.
3122 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3123 Add the enum PixelFormat values:
3124 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3125 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3127 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3128 The Mersenne Twister PRNG implemented through the av_random* functions
3129 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3132 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3133 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3134 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3135 and av_fifo_realloc2.
3136 In addition, the order of the function arguments of av_fifo_generic_read
3137 was changed to match av_fifo_generic_write.
3138 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3139 applications, they may not use sizeof() or directly access members.
3141 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3142 Introduce a new metadata API (see av_metadata_get() and friends).
3143 The old API is now deprecated and should not be used anymore. This especially
3144 includes the following structure fields:
3145 - AVFormatContext.title
3146 - AVFormatContext.author
3147 - AVFormatContext.copyright
3148 - AVFormatContext.comment
3149 - AVFormatContext.album
3150 - AVFormatContext.year
3151 - AVFormatContext.track
3152 - AVFormatContext.genre
3155 - AVProgram.provider_name
