154 Explicitly make avformat_network_init() and avformat_network_deinit() optional.
155 If these are not called, network initialization and deinitialization is
156 automatic, and unlike in older versions, fully supported, unless libavformat

164 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
166 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
167 Deprecate the entire library. Merged years ago to provide compatibility
168 with Libav, it remained unmaintained by the FFmpeg project and duplicated
169 functionality provided by libswresample.

172 Users of this library are asked to migrate to libswresample, which, as well as
173 providing more functionality, is faster and has higher accuracy.
175 2017-12-26 - a04c2c707d - lavc 58.9.100 - avcodec.h
176 Deprecate av_lockmgr_register(). You need to build FFmpeg with threading

233 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated
234 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
235 (avcodec_send_packet/avcodec_receive_frame) always work with reference
238 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
239 Add av_color_range_from_name(), av_color_primaries_from_name(),
240 av_color_transfer_from_name(), av_color_space_from_name(), and

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

286 2017-06-14 - d59c6a3aeb - lavu 55.66.100 - hwcontext.h
287 av_hwframe_ctx_create_derived() now takes some AV_HWFRAME_MAP_* combination

321 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
322 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
323 set the Cuda device handle.
325 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

349 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
350 (via an entry named "rotate"). Use av_stream_get_side_data() with
351 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
352 av_display_rotation_get(). The same is done for muxing. Instead of adding a
353 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
354 to be added to the AVStream.

362 Add AVCodecContext.hwaccel_flags field. This will control some hwaccels at
365 2017-03-21 - fc9f14c7de - lavf 57.67.100 / 57.08.0 - avio.h
366 Add AVIO_SEEKABLE_TIME flag.

369 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
370 bump, and libavformat will behave as if it were always set.
371 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().
373 2016-03-20 - 8200b16a9c - lavu 55.50.100 / 55.21.0 - imgutils.h

514 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
516 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be

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

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

3014 Make the pixdesc.h API public.
3016 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
3017 Add a next field to AVFilter, this is used for simplifying the
3018 registration and management of the registered filters.
3020 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
3021 Add a description field to AVFilter.
3023 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
3024 Change the interface of avfilter_make_format_list() from
3025 avfilter_make_format_list(int n, ...) to
3026 avfilter_make_format_list(enum PixelFormat *pix_fmts).
3028 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
3029 Make avfilter_get_video_buffer() recursive and add the w and h
3032 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
3033 Add w and h fields to AVFilterPic.
3035 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
3036 This is now an unsigned int instead of a signed int.
3038 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3039 Add a pts field to AVSubtitle which gives the subtitle packet pts
3040 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3041 not work right without this.
3043 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3044 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3045 major version. Use AV_PKT_FLAG_KEY instead.
3047 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3048 av_lockmgr_register() can be used to register a callback function
3049 that lavc (and in the future, libraries that depend on lavc) can use
3050 to implement mutexes. The application should provide a callback function
3051 that implements the AV_LOCK_* operations described in avcodec.h.
3052 When the lock manager is registered, FFmpeg is guaranteed to behave
3053 correctly in a multi-threaded application.
3055 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3056 av_free_packet() is no longer an inline function. It is now exported.
3058 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3059 Please use NULL instead. This has been supported since r16506
3060 (lavf > 52.23.1, lavc > 52.10.0).
3062 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3063 The old decoding functions are deprecated, all new code should use the
3064 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3065 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3066 argument instead of a const uint8_t *buf / int buf_size pair.
3068 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3069 Introduce the av_fifo_space() function.
3071 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3072 Move AVPacket declaration from libavformat/avformat.h to
3073 libavcodec/avcodec.h.
3075 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3076 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3077 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3078 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3079 PIX_FMT_BGR32_1 are now macros.
3080 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3081 Re-sort the enum PixelFormat list accordingly.
3082 This change breaks API/ABI backward compatibility.
3084 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3085 Add the enum PixelFormat values:
3086 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3087 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3089 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3090 The Mersenne Twister PRNG implemented through the av_random* functions
3091 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3094 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3095 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3096 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3097 and av_fifo_realloc2.
3098 In addition, the order of the function arguments of av_fifo_generic_read
3099 was changed to match av_fifo_generic_write.
3100 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3101 applications, they may not use sizeof() or directly access members.
3103 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3104 Introduce a new metadata API (see av_metadata_get() and friends).
3105 The old API is now deprecated and should not be used anymore. This especially
3106 includes the following structure fields:
3107 - AVFormatContext.title
3108 - AVFormatContext.author
3109 - AVFormatContext.copyright
3110 - AVFormatContext.comment
3111 - AVFormatContext.album
3112 - AVFormatContext.year
3113 - AVFormatContext.track
3114 - AVFormatContext.genre
3117 - AVProgram.provider_name
