95 Explicitly make avformat_network_init() and avformat_network_deinit() optional.
96 If these are not called, network initialization and deinitialization is
97 automatic, and unlike in older versions, fully supported, unless libavformat
98 is linked to ancient GnuTLS and OpenSSL.
100 2018-01-xx - xxxxxxx - lavf 58.4.100 - avformat.h
101 Deprecate AVStream.recommended_encoder_configuration. It was useful only for

107 2017-xx-xx - xxxxxxx - lavr 4.0.0 - avresample.h
108 Deprecate the entire library. Merged years ago to provide compatibility
109 with Libav, it remained unmaintained by the FFmpeg project and duplicated
110 functionality provided by libswresample.
112 In order to improve consistency and reduce attack surface, it has been deprecated.
113 Users of this library are asked to migrate to libswresample, which, as well as
114 providing more functionality, is faster and has higher accuracy.
116 2017-xx-xx - xxxxxxx - lavc 58.9.100 - avcodec.h
117 Deprecate av_lockmgr_register(). You need to build FFmpeg with threading
118 support enabled to get basic thread-safety (which is the default build

132 Add AV_CODEC_CAP_HARDWARE, AV_CODEC_CAP_HYBRID, and AVCodec.wrapper_name,

156 Add AV_PIX_FMT_OPENCL.
158 2017-11-11 - 48e4eda11d - lavc 58.3.100 - avcodec.h

175 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
176 (avcodec_send_packet/avcodec_receive_frame) always work with reference
179 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
180 Add av_color_range_from_name(), av_color_primaries_from_name(),

217 which can create the decoder context and allocate hardware frame automatically.
218 See AVCodecContext.hw_device_ctx and AVCodecContext.hw_frames_ctx. For D3D11,
219 the new AV_PIX_FMT_D3D11 pixfmt must be used with the new API.

228 av_hwframe_ctx_create_derived() now takes some AV_HWFRAME_MAP_* combination

262 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
263 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
264 set the Cuda device handle.
266 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

310 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
311 bump, and libavformat will behave as if it were always set.

331 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
332 native decoder format. (The default value is not changed.)

335 Remove requirement to use AVOption or accessors to access certain fields
336 in AVFrame, AVCodecContext, and AVFormatContext that were previously

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

522 that is not the case.
524 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
525 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
526 the reset of the ASS ReadOrder field on flush. This affects the content of
527 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
530 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
531 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
532 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
533 The default value for this option will change to "ass" at the next major
534 libavcodec version bump.
536 The current default is "ass_with_timings" for compatibility. This means that
537 all subtitles text decoders currently still output ASS with timings printed
538 as strings in the AVSubtitles.rects[N]->ass fields.
540 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
541 timing is limited to a 1/100 time base, so this is relevant for any subtitles
542 format needing a bigger one), ease timing adjustments, and prevents the need
543 of removing the timing from the decoded string yourself. This form is also
544 known as "the Matroska form". The timing information (start time, duration)
545 can be found in the AVSubtitles fields.

2979 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2980 Add a pts field to AVSubtitle which gives the subtitle packet pts
2981 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2982 not work right without this.
2984 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2985 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2986 major version. Use AV_PKT_FLAG_KEY instead.
2988 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2989 av_lockmgr_register() can be used to register a callback function
2990 that lavc (and in the future, libraries that depend on lavc) can use
2991 to implement mutexes. The application should provide a callback function
2992 that implements the AV_LOCK_* operations described in avcodec.h.
2993 When the lock manager is registered, FFmpeg is guaranteed to behave
2994 correctly in a multi-threaded application.
2996 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2997 av_free_packet() is no longer an inline function. It is now exported.
2999 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3000 Please use NULL instead. This has been supported since r16506
3001 (lavf > 52.23.1, lavc > 52.10.0).
3003 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3004 The old decoding functions are deprecated, all new code should use the
3005 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3006 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3007 argument instead of a const uint8_t *buf / int buf_size pair.
3009 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3010 Introduce the av_fifo_space() function.

3013 Move AVPacket declaration from libavformat/avformat.h to
3014 libavcodec/avcodec.h.
3016 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3017 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3018 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3019 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3020 PIX_FMT_BGR32_1 are now macros.
3021 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3022 Re-sort the enum PixelFormat list accordingly.
3023 This change breaks API/ABI backward compatibility.
3025 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3026 Add the enum PixelFormat values:

3030 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3031 The Mersenne Twister PRNG implemented through the av_random* functions
3032 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3035 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3036 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3037 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3038 and av_fifo_realloc2.
3039 In addition, the order of the function arguments of av_fifo_generic_read
3040 was changed to match av_fifo_generic_write.
3041 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3042 applications, they may not use sizeof() or directly access members.
3044 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
