89 options. Introduce "listen_timeout" as replacement for the current "timeout"
90 option, and "user_agent" as replacement for "user-agent". Once the deprecation
91 is over, the old "timeout" option will be removed, and "stimeout" will be
92 renamed to "stimeout" (the "timeout" option will essentially change semantics).
94 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h
95 Deprecate AVFormatContext filename field which had limited length, use the

108 Explicitly make avformat_network_init() and avformat_network_deinit() optional.
109 If these are not called, network initialization and deinitialization is
110 automatic, and unlike in older versions, fully supported, unless libavformat
111 is linked to ancient GnuTLS and OpenSSL.
113 2018-01-16 - 6512ff72f9 - lavf 58.4.100 - avformat.h
114 Deprecate AVStream.recommended_encoder_configuration. It was useful only for

117 2018-01-05 - 798dcf2432 - lavfi 7.11.101 - avfilter.h
118 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
120 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
121 Deprecate the entire library. Merged years ago to provide compatibility
122 with Libav, it remained unmaintained by the FFmpeg project and duplicated
123 functionality provided by libswresample.
125 In order to improve consistency and reduce attack surface, it has been deprecated.
126 Users of this library are asked to migrate to libswresample, which, as well as
127 providing more functionality, is faster and has higher accuracy.
129 2017-12-26 - a04c2c707d - lavc 58.9.100 - avcodec.h
130 Deprecate av_lockmgr_register(). You need to build FFmpeg with threading
131 support enabled to get basic thread-safety (which is the default build
134 2017-12-24 - 8b81eabe57 - lavu 56.7.100 - cpu.h

169 Add AV_PIX_FMT_OPENCL.
171 2017-11-11 - 48e4eda11d - lavc 58.3.100 - avcodec.h
172 Add avcodec_get_hw_frames_parameters().

187 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated
188 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
189 (avcodec_send_packet/avcodec_receive_frame) always work with reference
192 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
193 Add av_color_range_from_name(), av_color_primaries_from_name(),

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

241 av_hwframe_ctx_create_derived() now takes some AV_HWFRAME_MAP_* combination

275 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
276 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
277 set the Cuda device handle.
279 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

303 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
304 (via an entry named "rotate"). Use av_stream_get_side_data() with
305 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
306 av_display_rotation_get(). The same is done for muxing. Instead of adding a
307 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
308 to be added to the AVStream.

323 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
324 bump, and libavformat will behave as if it were always set.
325 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().
327 2016-03-20 - 8200b16a9c - lavu 55.50.100 / 55.21.0 - imgutils.h

344 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
345 native decoder format. (The default value is not changed.)
347 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
348 Remove requirement to use AVOption or accessors to access certain fields
349 in AVFrame, AVCodecContext, and AVFormatContext that were previously
350 documented as "no direct access" allowed.

367 2017-01-17 - 2a4a8653b6 - lavc 57.74.100 - vaapi.h
368 Deprecate struct vaapi_context and the vaapi.h installed header.

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

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

543 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
544 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
545 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
546 The default value for this option will change to "ass" at the next major
547 libavcodec version bump.
549 The current default is "ass_with_timings" for compatibility. This means that
550 all subtitles text decoders currently still output ASS with timings printed
551 as strings in the AVSubtitles.rects[N]->ass fields.
553 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
554 timing is limited to a 1/100 time base, so this is relevant for any subtitles
555 format needing a bigger one), ease timing adjustments, and prevents the need
556 of removing the timing from the decoded string yourself. This form is also
557 known as "the Matroska form". The timing information (start time, duration)
558 can be found in the AVSubtitles fields.

3019 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3020 argument instead of a const uint8_t *buf / int buf_size pair.
3022 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3023 Introduce the av_fifo_space() function.
3025 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3026 Move AVPacket declaration from libavformat/avformat.h to
3027 libavcodec/avcodec.h.
3029 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3030 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3031 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3032 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3033 PIX_FMT_BGR32_1 are now macros.
3034 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3035 Re-sort the enum PixelFormat list accordingly.
3036 This change breaks API/ABI backward compatibility.
3038 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3039 Add the enum PixelFormat values:
3040 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3041 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3043 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3044 The Mersenne Twister PRNG implemented through the av_random* functions
3045 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3048 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3049 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3050 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3051 and av_fifo_realloc2.
3052 In addition, the order of the function arguments of av_fifo_generic_read
3053 was changed to match av_fifo_generic_write.
3054 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3055 applications, they may not use sizeof() or directly access members.
3057 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3058 Introduce a new metadata API (see av_metadata_get() and friends).
3059 The old API is now deprecated and should not be used anymore. This especially
3060 includes the following structure fields:
3061 - AVFormatContext.title
3062 - AVFormatContext.author
3063 - AVFormatContext.copyright
3064 - AVFormatContext.comment
3065 - AVFormatContext.album
3066 - AVFormatContext.year
3067 - AVFormatContext.track
3068 - AVFormatContext.genre
3071 - AVProgram.provider_name
