101 options. Introduce "listen_timeout" as replacement for the current "timeout"
102 option, and "user_agent" as replacement for "user-agent". Once the deprecation
103 is over, the old "timeout" option will be removed, and "stimeout" will be
104 renamed to "stimeout" (the "timeout" option will essentially change semantics).
106 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h
107 Deprecate AVFormatContext filename field which had limited length, use the

120 Explicitly make avformat_network_init() and avformat_network_deinit() optional.
121 If these are not called, network initialization and deinitialization is
122 automatic, and unlike in older versions, fully supported, unless libavformat
123 is linked to ancient GnuTLS and OpenSSL.
125 2018-01-16 - 6512ff72f9 - lavf 58.4.100 - avformat.h
126 Deprecate AVStream.recommended_encoder_configuration. It was useful only for

129 2018-01-05 - 798dcf2432 - lavfi 7.11.101 - avfilter.h
130 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
132 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
133 Deprecate the entire library. Merged years ago to provide compatibility
134 with Libav, it remained unmaintained by the FFmpeg project and duplicated
135 functionality provided by libswresample.
137 In order to improve consistency and reduce attack surface, it has been deprecated.
138 Users of this library are asked to migrate to libswresample, which, as well as
139 providing more functionality, is faster and has higher accuracy.
141 2017-12-26 - a04c2c707d - lavc 58.9.100 - avcodec.h
142 Deprecate av_lockmgr_register(). You need to build FFmpeg with threading
143 support enabled to get basic thread-safety (which is the default build

181 Add AV_PIX_FMT_OPENCL.
183 2017-11-11 - 48e4eda11d - lavc 58.3.100 - avcodec.h
184 Add avcodec_get_hw_frames_parameters().

198 2017-09-26 - b1cf151c4d - lavc 57.106.102 - avcodec.h
199 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated
200 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
201 (avcodec_send_packet/avcodec_receive_frame) always work with reference
204 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
205 Add av_color_range_from_name(), av_color_primaries_from_name(),
206 av_color_transfer_from_name(), av_color_space_from_name(), and

241 DXVA2 and D3D11 hardware accelerated decoding now supports the new hwaccel API,
242 which can create the decoder context and allocate hardware frame automatically.
243 See AVCodecContext.hw_device_ctx and AVCodecContext.hw_frames_ctx. For D3D11,
244 the new AV_PIX_FMT_D3D11 pixfmt must be used with the new API.

252 2017-06-14 - d59c6a3aeb - lavu 55.66.100 - hwcontext.h
253 av_hwframe_ctx_create_derived() now takes some AV_HWFRAME_MAP_* combination

287 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
288 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
289 set the Cuda device handle.
291 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

315 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
316 (via an entry named "rotate"). Use av_stream_get_side_data() with
317 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
318 av_display_rotation_get(). The same is done for muxing. Instead of adding a
319 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
320 to be added to the AVStream.

335 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
336 bump, and libavformat will behave as if it were always set.
337 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().

356 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
357 native decoder format. (The default value is not changed.)
359 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
360 Remove requirement to use AVOption or accessors to access certain fields
361 in AVFrame, AVCodecContext, and AVFormatContext that were previously
362 documented as "no direct access" allowed.

380 Deprecate struct vaapi_context and the vaapi.h installed header.

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

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

555 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
556 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
557 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
558 The default value for this option will change to "ass" at the next major
559 libavcodec version bump.
561 The current default is "ass_with_timings" for compatibility. This means that
562 all subtitles text decoders currently still output ASS with timings printed
563 as strings in the AVSubtitles.rects[N]->ass fields.
565 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
566 timing is limited to a 1/100 time base, so this is relevant for any subtitles
567 format needing a bigger one), ease timing adjustments, and prevents the need
568 of removing the timing from the decoded string yourself. This form is also
569 known as "the Matroska form". The timing information (start time, duration)
570 can be found in the AVSubtitles fields.

3018 When the lock manager is registered, FFmpeg is guaranteed to behave
3019 correctly in a multi-threaded application.
3021 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3022 av_free_packet() is no longer an inline function. It is now exported.
3024 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3025 Please use NULL instead. This has been supported since r16506
3026 (lavf > 52.23.1, lavc > 52.10.0).
3028 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3029 The old decoding functions are deprecated, all new code should use the
3030 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3031 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3032 argument instead of a const uint8_t *buf / int buf_size pair.
3034 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3035 Introduce the av_fifo_space() function.
3037 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3038 Move AVPacket declaration from libavformat/avformat.h to
3039 libavcodec/avcodec.h.
3041 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3042 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3043 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3044 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3045 PIX_FMT_BGR32_1 are now macros.
3046 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3047 Re-sort the enum PixelFormat list accordingly.
3048 This change breaks API/ABI backward compatibility.
3050 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3051 Add the enum PixelFormat values:
3052 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3053 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3055 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3056 The Mersenne Twister PRNG implemented through the av_random* functions
3057 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3060 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3061 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3062 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3063 and av_fifo_realloc2.
3064 In addition, the order of the function arguments of av_fifo_generic_read
3065 was changed to match av_fifo_generic_write.
3066 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3067 applications, they may not use sizeof() or directly access members.
3069 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3070 Introduce a new metadata API (see av_metadata_get() and friends).
3071 The old API is now deprecated and should not be used anymore. This especially
3072 includes the following structure fields:
3073 - AVFormatContext.title
3074 - AVFormatContext.author
3075 - AVFormatContext.copyright
3076 - AVFormatContext.comment
3077 - AVFormatContext.album
3078 - AVFormatContext.year
3079 - AVFormatContext.track
3080 - AVFormatContext.genre
3083 - AVProgram.provider_name
