69 Add requirement to bitstream filtering API that returned packets with
70 size == 0 and side_data_elems == 0 are to be skipped by the caller.
72 2016-03-04 - 9362973 - lavf 57.28.100
73 Add protocol blacklisting API
75 2016-02-28 - 4dd4d53 - lavc 57.27.101
76 Validate AVFrame returned by get_buffer2 to have required
77 planes not NULL and unused planes set to NULL as crashes
78 and buffer overflow are possible with certain streams if
81 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
82 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
83 the reset of the ASS ReadOrder field on flush. This affects the content of
84 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
87 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
88 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
89 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
90 The default value for this option will change to "ass" at the next major
91 libavcodec version bump.
93 The current default is "ass_with_timings" for compatibility. This means that
94 all subtitles text decoders currently still output ASS with timings printed
95 as strings in the AVSubtitles.rects[N]->ass fields.
97 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
98 timing is limited to a 1/100 time base, so this is relevant for any subtitles
99 format needing a bigger one), ease timing adjustments, and prevents the need
100 of removing the timing from the decoded string yourself. This form is also
101 known as "the Matroska form". The timing information (start time, duration)
102 can be found in the AVSubtitles fields.

2507 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2508 Change the signature of avfilter_register() to make it return an
2509 int. This is required since now the registration operation may fail.
2511 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2512 Make the pixdesc.h API public.

2536 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2537 Add a pts field to AVSubtitle which gives the subtitle packet pts
2538 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

2541 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2542 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2543 major version. Use AV_PKT_FLAG_KEY instead.
2545 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2546 av_lockmgr_register() can be used to register a callback function
2547 that lavc (and in the future, libraries that depend on lavc) can use
2548 to implement mutexes. The application should provide a callback function
2549 that implements the AV_LOCK_* operations described in avcodec.h.
2550 When the lock manager is registered, FFmpeg is guaranteed to behave
2551 correctly in a multi-threaded application.
2553 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2554 av_free_packet() is no longer an inline function. It is now exported.
2556 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2557 Please use NULL instead. This has been supported since r16506
2558 (lavf > 52.23.1, lavc > 52.10.0).
2560 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2561 The old decoding functions are deprecated, all new code should use the
2562 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2563 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2564 argument instead of a const uint8_t *buf / int buf_size pair.
2566 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2567 Introduce the av_fifo_space() function.
2569 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2570 Move AVPacket declaration from libavformat/avformat.h to
2571 libavcodec/avcodec.h.
2573 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2574 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2575 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2576 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2577 PIX_FMT_BGR32_1 are now macros.
2578 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2579 Re-sort the enum PixelFormat list accordingly.
2580 This change breaks API/ABI backward compatibility.
2582 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2583 Add the enum PixelFormat values:
2584 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2585 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2587 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2588 The Mersenne Twister PRNG implemented through the av_random* functions
2589 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2592 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2593 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2594 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2595 and av_fifo_realloc2.
2596 In addition, the order of the function arguments of av_fifo_generic_read
2597 was changed to match av_fifo_generic_write.
2598 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2599 applications, they may not use sizeof() or directly access members.
2601 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2602 Introduce a new metadata API (see av_metadata_get() and friends).
2603 The old API is now deprecated and should not be used anymore. This especially
2604 includes the following structure fields:
2605 - AVFormatContext.title
2606 - AVFormatContext.author
2607 - AVFormatContext.copyright
2608 - AVFormatContext.comment
2609 - AVFormatContext.album
2610 - AVFormatContext.year
2611 - AVFormatContext.track
2612 - AVFormatContext.genre
2615 - AVProgram.provider_name
