468 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
469 (via an entry named "rotate"). Use av_stream_get_side_data() with
470 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
471 av_display_rotation_get(). The same is done for muxing. Instead of adding a
472 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
473 to be added to the AVStream.

578 Decoders now export the frame timestamp as AVFrame.pts. It was
579 previously exported as AVFrame.pkt_pts, which is now deprecated.
581 Note: When decoding, AVFrame.pts uses the stream/packet timebase,

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

703 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing

708 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
709 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
710 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
711 The default value for this option will change to "ass" at the next major
712 libavcodec version bump.
714 The current default is "ass_with_timings" for compatibility. This means that
715 all subtitles text decoders currently still output ASS with timings printed
716 as strings in the AVSubtitles.rects[N]->ass fields.
718 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
719 timing is limited to a 1/100 time base, so this is relevant for any subtitles
720 format needing a bigger one), ease timing adjustments, and prevents the need
721 of removing the timing from the decoded string yourself. This form is also
722 known as "the Matroska form". The timing information (start time, duration)
723 can be found in the AVSubtitles fields.

1977 For audio formats with fixed frame size, the last frame

3125 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3126 Introduce the avfilter_next() function.
3128 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3129 Change the signature of avfilter_register() to make it return an
3130 int. This is required since now the registration operation may fail.
3132 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3133 Make the pixdesc.h API public.

3157 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3158 Add a pts field to AVSubtitle which gives the subtitle packet pts
3159 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3160 not work right without this.
3162 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3163 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3164 major version. Use AV_PKT_FLAG_KEY instead.
3166 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3167 av_lockmgr_register() can be used to register a callback function
3168 that lavc (and in the future, libraries that depend on lavc) can use
3169 to implement mutexes. The application should provide a callback function
3170 that implements the AV_LOCK_* operations described in avcodec.h.
3171 When the lock manager is registered, FFmpeg is guaranteed to behave
3172 correctly in a multi-threaded application.
3174 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3175 av_free_packet() is no longer an inline function. It is now exported.
3177 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3178 Please use NULL instead. This has been supported since r16506
3179 (lavf > 52.23.1, lavc > 52.10.0).
3181 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3182 The old decoding functions are deprecated, all new code should use the
3183 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3184 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3185 argument instead of a const uint8_t *buf / int buf_size pair.
3187 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3188 Introduce the av_fifo_space() function.
3190 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3191 Move AVPacket declaration from libavformat/avformat.h to
3192 libavcodec/avcodec.h.
3194 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3195 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3196 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3197 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3198 PIX_FMT_BGR32_1 are now macros.
3199 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3200 Re-sort the enum PixelFormat list accordingly.
3201 This change breaks API/ABI backward compatibility.
3203 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3204 Add the enum PixelFormat values:
3205 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3206 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3208 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3209 The Mersenne Twister PRNG implemented through the av_random* functions
3210 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3213 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3214 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3215 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3216 and av_fifo_realloc2.
3217 In addition, the order of the function arguments of av_fifo_generic_read
3218 was changed to match av_fifo_generic_write.
3219 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3220 applications, they may not use sizeof() or directly access members.
3222 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3223 Introduce a new metadata API (see av_metadata_get() and friends).
3224 The old API is now deprecated and should not be used anymore. This especially
3225 includes the following structure fields:
3226 - AVFormatContext.title
3227 - AVFormatContext.author
3228 - AVFormatContext.copyright
3229 - AVFormatContext.comment
3230 - AVFormatContext.album
3231 - AVFormatContext.year
3232 - AVFormatContext.track
3233 - AVFormatContext.genre
3236 - AVProgram.provider_name
