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

117 Add requirement to bitstream filtering API that returned packets with
118 size == 0 and side_data_elems == 0 are to be skipped by the caller.
120 2016-03-04 - 9362973 - lavf 57.28.100

126 and buffer overflow are possible with certain streams if
127 that is not the case.
129 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
130 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
131 the reset of the ASS ReadOrder field on flush. This affects the content of
132 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
135 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
136 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
137 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
138 The default value for this option will change to "ass" at the next major
139 libavcodec version bump.
141 The current default is "ass_with_timings" for compatibility. This means that
142 all subtitles text decoders currently still output ASS with timings printed
143 as strings in the AVSubtitles.rects[N]->ass fields.
145 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
146 timing is limited to a 1/100 time base, so this is relevant for any subtitles
147 format needing a bigger one), ease timing adjustments, and prevents the need
148 of removing the timing from the decoded string yourself. This form is also
149 known as "the Matroska form". The timing information (start time, duration)
150 can be found in the AVSubtitles fields.

2555 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2556 Change the signature of avfilter_register() to make it return an
2557 int. This is required since now the registration operation may fail.
2559 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API

2584 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2585 Add a pts field to AVSubtitle which gives the subtitle packet pts
2586 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2587 not work right without this.
2589 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2590 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2591 major version. Use AV_PKT_FLAG_KEY instead.
2593 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2594 av_lockmgr_register() can be used to register a callback function
2595 that lavc (and in the future, libraries that depend on lavc) can use
2596 to implement mutexes. The application should provide a callback function
2597 that implements the AV_LOCK_* operations described in avcodec.h.
2598 When the lock manager is registered, FFmpeg is guaranteed to behave
2599 correctly in a multi-threaded application.
2601 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2602 av_free_packet() is no longer an inline function. It is now exported.
2604 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2605 Please use NULL instead. This has been supported since r16506
2606 (lavf > 52.23.1, lavc > 52.10.0).
2608 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2609 The old decoding functions are deprecated, all new code should use the
2610 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2611 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2612 argument instead of a const uint8_t *buf / int buf_size pair.
2614 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2615 Introduce the av_fifo_space() function.
2617 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2618 Move AVPacket declaration from libavformat/avformat.h to
2619 libavcodec/avcodec.h.
2621 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2622 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2623 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2624 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2625 PIX_FMT_BGR32_1 are now macros.
2626 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2627 Re-sort the enum PixelFormat list accordingly.
2628 This change breaks API/ABI backward compatibility.
2630 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2631 Add the enum PixelFormat values:
2632 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2633 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2635 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2636 The Mersenne Twister PRNG implemented through the av_random* functions
2637 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2640 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2641 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2642 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2643 and av_fifo_realloc2.
2644 In addition, the order of the function arguments of av_fifo_generic_read
2645 was changed to match av_fifo_generic_write.
2646 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2647 applications, they may not use sizeof() or directly access members.
2649 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2650 Introduce a new metadata API (see av_metadata_get() and friends).
2651 The old API is now deprecated and should not be used anymore. This especially
2652 includes the following structure fields:
2653 - AVFormatContext.title
2654 - AVFormatContext.author
2655 - AVFormatContext.copyright
2656 - AVFormatContext.comment
2657 - AVFormatContext.album
2658 - AVFormatContext.year
2659 - AVFormatContext.track
2660 - AVFormatContext.genre
2663 - AVProgram.provider_name
