16 API changes, most recent first:
18 2016-xx-xx - xxxxxxx - lavc 57.37.100 - avcodec.h
19 Add a new audio/video encoding and decoding API with decoupled input
20 and output -- avcodec_send_packet(), avcodec_receive_frame(),
21 avcodec_send_frame() and avcodec_receive_packet().
23 2016-xx-xx - xxxxxxx - lavc 57.15.0 - avcodec.h
24 Add a new bitstream filtering API working with AVPackets.
25 Deprecate the old bistream filtering API.
27 2016-xx-xx - xxxxxxx - lavfi 6.42.0 - avfilter.h
28 Add AVFilterContext.hw_device_ctx.
30 2016-xx-xx - xxxxxxx - lavu 55.22.0 - hwcontext_vaapi.h
31 Add new installed header with VAAPI-specific hwcontext definitions.
33 2016-xx-xx - xxxxxxx - lavu 55.21.0 - hwcontext.h
34 Add AVHWFramesConstraints and associated API.
36 2016-04-11 - xxxxxxx - lavf 57.33.0 - avformat.h
37 Add AVStream.codecpar, deprecate AVStream.codec.
39 2016-04-02 - xxxxxxx - lavu 55.20.100 - base64.h
40 Add AV_BASE64_DECODE_SIZE(x) macro.
42 2016-xx-xx - lavc 57.33.0 - avcodec.h
43 xxxxxxx - Add AVCodecParameters and its related API.
44 xxxxxxx - Add av_get_audio_frame_duration2().
46 2016-03-11 - xxxxxxx - lavf/lavc 57.28.101
47 Add requirement to bitstream filtering API that returned packets with
48 size == 0 and side_data_elems == 0 are to be skipped by the caller.
50 2016-XX-XX - xxxxxxx - lavf 57.28.100
51 Add protocol blacklisting API
53 2016-02-28 - xxxxxxx - lavc 57.27.101
54 Validate AVFrame returned by get_buffer2 to have required
55 planes not NULL and unused planes set to NULL as crashes
56 and buffer overflow are possible with certain streams if
59 2016-xx-xx - xxxxxxx - lavc 57.27.100 - avcodec.h
60 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
61 the reset of the ASS ReadOrder field on flush. This affects the content of
62 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
65 2016-xx-xx - xxxxxxx - lavc 57.26.100 - avcodec.h
66 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
67 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
68 The default value for this option will change to "ass" at the next major
69 libavcodec version bump.
71 The current default is "ass_with_timings" for compatibility. This means that
72 all subtitles text decoders currently still output ASS with timings printed
73 as strings in the AVSubtitles.rects[N]->ass fields.
75 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
76 timing is limited to a 1/100 time base, so this is relevant for any subtitles
77 format needing a bigger one), ease timing adjustments, and prevents the need
78 of removing the timing from the decoded string yourself. This form is also
79 known as "the Matroska form". The timing information (start time, duration)
80 can be found in the AVSubtitles fields.
82 2016-xx-xx - lavc 57.25.0 - avcodec.h
83 Add AVCodecContext.hw_frames_ctx.
85 2016-xx-xx - lavfi 6.36.0 - avfilter.h

89 2016-02-xx - xxxxxxx - lavc 57.25.100
90 Add AV_PKT_DATA_MPEGTS_STREAM_ID for exporting the MPEGTS stream ID.
92 2016-xx-xx - lavu 55.18.100
93 xxxxxxx audio_fifo.h - Add av_audio_fifo_peek_at().
95 2016-xx-xx - lavu 55.18.0
96 xxxxxxx buffer.h - Add av_buffer_pool_init2().

1277 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
1278 To provide backwards compatibility, CodecID is now #defined as AVCodecID.

1334 For audio formats with fixed frame size, the last frame
1335 no longer needs to be padded with silence, libavcodec
1336 will handle this internally (effectively all encoders

2281 enum PixelFormat *formats -> int *formats in AVFilterFormats
2282 enum PixelFormat *format -> int format in AVFilterLink
2284 Change the function signatures:
2285 AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
2286 AVFilterFormats *avfilter_make_format_list(const int *fmts);
2288 int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
2289 int avfilter_add_format (AVFilterFormats **avff, int fmt);
2291 AVFilterFormats *avfilter_all_colorspaces(void); ->
2292 AVFilterFormats *avfilter_all_formats (enum AVMediaType type);
2294 This change breaks libavfilter API/ABI.

2485 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2486 Change the signature of avfilter_register() to make it return an
2487 int. This is required since now the registration operation may fail.
2489 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2490 Make the pixdesc.h API public.
2492 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2511 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2512 This is now an unsigned int instead of a signed int.
2514 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2515 Add a pts field to AVSubtitle which gives the subtitle packet pts
2516 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2517 not work right without this.
2519 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2520 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2521 major version. Use AV_PKT_FLAG_KEY instead.
2523 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2524 av_lockmgr_register() can be used to register a callback function
2525 that lavc (and in the future, libraries that depend on lavc) can use
2526 to implement mutexes. The application should provide a callback function
2527 that implements the AV_LOCK_* operations described in avcodec.h.
2528 When the lock manager is registered, FFmpeg is guaranteed to behave
2529 correctly in a multi-threaded application.
2531 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2532 av_free_packet() is no longer an inline function. It is now exported.
2534 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2535 Please use NULL instead. This has been supported since r16506
2536 (lavf > 52.23.1, lavc > 52.10.0).
2538 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2539 The old decoding functions are deprecated, all new code should use the
2540 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2541 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2542 argument instead of a const uint8_t *buf / int buf_size pair.
2544 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2545 Introduce the av_fifo_space() function.
2547 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2548 Move AVPacket declaration from libavformat/avformat.h to
2549 libavcodec/avcodec.h.
2551 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2552 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2553 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2554 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2555 PIX_FMT_BGR32_1 are now macros.
2556 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2557 Re-sort the enum PixelFormat list accordingly.
2558 This change breaks API/ABI backward compatibility.
2560 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2561 Add the enum PixelFormat values:
2562 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2563 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2565 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2566 The Mersenne Twister PRNG implemented through the av_random* functions
2567 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2570 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2571 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2572 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2573 and av_fifo_realloc2.
2574 In addition, the order of the function arguments of av_fifo_generic_read
2575 was changed to match av_fifo_generic_write.
2576 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2577 applications, they may not use sizeof() or directly access members.
2579 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2580 Introduce a new metadata API (see av_metadata_get() and friends).
2581 The old API is now deprecated and should not be used anymore. This especially
2582 includes the following structure fields:
2583 - AVFormatContext.title
2584 - AVFormatContext.author
2585 - AVFormatContext.copyright
2586 - AVFormatContext.comment
2587 - AVFormatContext.album
2588 - AVFormatContext.year
2589 - AVFormatContext.track
2590 - AVFormatContext.genre
2593 - AVProgram.provider_name
