151 Explicitly make avformat_network_init() and avformat_network_deinit() optional.
152 If these are not called, network initialization and deinitialization is

169 Users of this library are asked to migrate to libswresample, which, as well as
170 providing more functionality, is faster and has higher accuracy.
172 2017-12-26 - a04c2c707d - lavc 58.9.100 - avcodec.h

346 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
347 (via an entry named "rotate"). Use av_stream_get_side_data() with
348 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with

511 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.

581 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
582 the reset of the ASS ReadOrder field on flush. This affects the content of

586 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
587 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
588 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
589 The default value for this option will change to "ass" at the next major
590 libavcodec version bump.
592 The current default is "ass_with_timings" for compatibility. This means that
593 all subtitles text decoders currently still output ASS with timings printed
594 as strings in the AVSubtitles.rects[N]->ass fields.
596 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
597 timing is limited to a 1/100 time base, so this is relevant for any subtitles
598 format needing a bigger one), ease timing adjustments, and prevents the need
599 of removing the timing from the decoded string yourself. This form is also
600 known as "the Matroska form". The timing information (start time, duration)
601 can be found in the AVSubtitles fields.

3023 avfilter_make_format_list(enum PixelFormat *pix_fmts).
3025 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
3026 Make avfilter_get_video_buffer() recursive and add the w and h
3029 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
3030 Add w and h fields to AVFilterPic.
3032 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3033 This is now an unsigned int instead of a signed int.
3035 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3036 Add a pts field to AVSubtitle which gives the subtitle packet pts
3037 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3038 not work right without this.
3040 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3041 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3042 major version. Use AV_PKT_FLAG_KEY instead.
3044 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3045 av_lockmgr_register() can be used to register a callback function
3046 that lavc (and in the future, libraries that depend on lavc) can use
3047 to implement mutexes. The application should provide a callback function
3048 that implements the AV_LOCK_* operations described in avcodec.h.
3049 When the lock manager is registered, FFmpeg is guaranteed to behave
3050 correctly in a multi-threaded application.
3052 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3053 av_free_packet() is no longer an inline function. It is now exported.
3055 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3056 Please use NULL instead. This has been supported since r16506
3057 (lavf > 52.23.1, lavc > 52.10.0).
3059 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3060 The old decoding functions are deprecated, all new code should use the
3061 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3062 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3063 argument instead of a const uint8_t *buf / int buf_size pair.
3065 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3066 Introduce the av_fifo_space() function.
3068 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3069 Move AVPacket declaration from libavformat/avformat.h to
3070 libavcodec/avcodec.h.
3072 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3073 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3074 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3075 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3076 PIX_FMT_BGR32_1 are now macros.
3077 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3078 Re-sort the enum PixelFormat list accordingly.
3079 This change breaks API/ABI backward compatibility.
3081 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3082 Add the enum PixelFormat values:
3083 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3084 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3086 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3087 The Mersenne Twister PRNG implemented through the av_random* functions
3088 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3091 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3092 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3093 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3094 and av_fifo_realloc2.
3095 In addition, the order of the function arguments of av_fifo_generic_read
3096 was changed to match av_fifo_generic_write.
3097 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3098 applications, they may not use sizeof() or directly access members.
3100 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3101 Introduce a new metadata API (see av_metadata_get() and friends).
3102 The old API is now deprecated and should not be used anymore. This especially
3103 includes the following structure fields:
3104 - AVFormatContext.title
3105 - AVFormatContext.author
3106 - AVFormatContext.copyright
3107 - AVFormatContext.comment
3108 - AVFormatContext.album
3109 - AVFormatContext.year
3110 - AVFormatContext.track
3111 - AVFormatContext.genre
3114 - AVProgram.provider_name
