60 2016-03-11 - 6d8ab35 - lavf/lavc 57.28.101
61 Add requirement to bitstream filtering API that returned packets with
62 size == 0 and side_data_elems == 0 are to be skipped by the caller.
64 2016-03-04 - 9362973 - lavf 57.28.100
65 Add protocol blacklisting API
67 2016-02-28 - 4dd4d53 - lavc 57.27.101
68 Validate AVFrame returned by get_buffer2 to have required
69 planes not NULL and unused planes set to NULL as crashes
70 and buffer overflow are possible with certain streams if
73 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
74 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
75 the reset of the ASS ReadOrder field on flush. This affects the content of
76 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
79 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
80 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
81 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
82 The default value for this option will change to "ass" at the next major
83 libavcodec version bump.
85 The current default is "ass_with_timings" for compatibility. This means that
86 all subtitles text decoders currently still output ASS with timings printed
87 as strings in the AVSubtitles.rects[N]->ass fields.
89 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
90 timing is limited to a 1/100 time base, so this is relevant for any subtitles
91 format needing a bigger one), ease timing adjustments, and prevents the need
92 of removing the timing from the decoded string yourself. This form is also
93 known as "the Matroska form". The timing information (start time, duration)
94 can be found in the AVSubtitles fields.
96 2016-xx-xx - lavc 57.25.0 - avcodec.h
97 Add AVCodecContext.hw_frames_ctx.
99 2016-xx-xx - lavfi 6.36.0 - avfilter.h

103 2016-02-23 - 14f7a3d - lavc 57.25.100
104 Add AV_PKT_DATA_MPEGTS_STREAM_ID for exporting the MPEGTS stream ID.
106 2016-xx-xx - lavu 55.18.100
107 xxxxxxx audio_fifo.h - Add av_audio_fifo_peek_at().
109 2016-xx-xx - lavu 55.18.0
110 xxxxxxx buffer.h - Add av_buffer_pool_init2().
111 xxxxxxx hwcontext.h - Add a new installed header hwcontext.h with a new API
112 for handling hwaccel frames.

114 CUDA-specific hwcontext definitions.
115 xxxxxxx hwcontext_vdpau.h - Add a new installed header hwcontext_vdpau.h with
116 VDPAU-specific hwcontext definitions.

2295 enum PixelFormat *formats -> int *formats in AVFilterFormats
2296 enum PixelFormat *format -> int format in AVFilterLink
2298 Change the function signatures:
2299 AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->

2496 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2497 Introduce the avfilter_next() function.
2499 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2500 Change the signature of avfilter_register() to make it return an
2501 int. This is required since now the registration operation may fail.
2503 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2504 Make the pixdesc.h API public.
2506 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2523 Add w and h fields to AVFilterPic.
2525 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2526 This is now an unsigned int instead of a signed int.
2528 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2529 Add a pts field to AVSubtitle which gives the subtitle packet pts
2530 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2531 not work right without this.
2533 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2534 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2535 major version. Use AV_PKT_FLAG_KEY instead.
2537 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2538 av_lockmgr_register() can be used to register a callback function
2539 that lavc (and in the future, libraries that depend on lavc) can use
2540 to implement mutexes. The application should provide a callback function
2541 that implements the AV_LOCK_* operations described in avcodec.h.
2542 When the lock manager is registered, FFmpeg is guaranteed to behave
2543 correctly in a multi-threaded application.
2545 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2546 av_free_packet() is no longer an inline function. It is now exported.
2548 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2549 Please use NULL instead. This has been supported since r16506
2550 (lavf > 52.23.1, lavc > 52.10.0).
2552 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2553 The old decoding functions are deprecated, all new code should use the
2554 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2555 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2556 argument instead of a const uint8_t *buf / int buf_size pair.
2558 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2559 Introduce the av_fifo_space() function.
2561 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2562 Move AVPacket declaration from libavformat/avformat.h to
2563 libavcodec/avcodec.h.
2565 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2566 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2567 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2568 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2569 PIX_FMT_BGR32_1 are now macros.
2570 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2571 Re-sort the enum PixelFormat list accordingly.
2572 This change breaks API/ABI backward compatibility.
2574 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2575 Add the enum PixelFormat values:
2576 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2577 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2579 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2580 The Mersenne Twister PRNG implemented through the av_random* functions
2581 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2584 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2585 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2586 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2587 and av_fifo_realloc2.
2588 In addition, the order of the function arguments of av_fifo_generic_read
2589 was changed to match av_fifo_generic_write.
2590 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2591 applications, they may not use sizeof() or directly access members.
2593 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2594 Introduce a new metadata API (see av_metadata_get() and friends).
2595 The old API is now deprecated and should not be used anymore. This especially
2596 includes the following structure fields:
2597 - AVFormatContext.title
2598 - AVFormatContext.author
2599 - AVFormatContext.copyright
2600 - AVFormatContext.comment
2601 - AVFormatContext.album
2602 - AVFormatContext.year
2603 - AVFormatContext.track
2604 - AVFormatContext.genre
2607 - AVProgram.provider_name
