756 data. Add new API for working with reference-counted AVFrames.
757 759001c - add the refcounted_frames field to AVCodecContext to make audio and
758 video decoders return reference-counted frames. Add get_buffer2()
759 callback to AVCodecContext which allocates reference-counted frames.
760 Add avcodec_default_get_buffer2() as the default get_buffer2()
761 implementation.
762 Deprecate AVCodecContext.get_buffer() / release_buffer() /
763 reget_buffer(), avcodec_default_get_buffer(),
764 avcodec_default_reget_buffer(), avcodec_default_release_buffer().
765 Remove avcodec_default_free_buffers(), which should not have ever
766 been called from outside of lavc.
767 Deprecate the following AVFrame fields:
768 * base -- is now stored in AVBufferRef
769 * reference, type, buffer_hints -- are unnecessary in the new API
770 * hwaccel_picture_private, owner, thread_opaque -- should not
771 have been accessed from outside of lavc
772 * qscale_table, qstride, qscale_type, mbskip_table, motion_val,
773 mb_type, dct_coeff, ref_index -- mpegvideo-specific tables,
774 which are not exported anymore.
775 7e35037 - switch libavfilter to use AVFrame instead of AVFilterBufferRef. Add
776 av_buffersrc_add_frame(), deprecate av_buffersrc_buffer().
777 Add av_buffersink_get_frame() and av_buffersink_get_samples(),
778 deprecate av_buffersink_read() and av_buffersink_read_samples().
779 Deprecate AVFilterBufferRef and all functions for working with it.

840 To provide backwards compatibility, PixelFormat is now #defined as
841 AVPixelFormat.

843 'PixelFormat' identifier. Such code should either #undef PixelFormat
844 or stop using the PixelFormat name.

947 For audio formats with fixed frame size, the last frame
948 no longer needs to be padded with silence, libavcodec
949 will handle this internally (effectively all encoders

1042 f1caf01 Allow doing av_write_frame(ctx, NULL) for flushing possible
1043 buffered data within a muxer. Added AVFMT_ALLOW_FLUSH for

1064
1065 2011-12-25 - lavfi 2.14.0
1066 e1d9dbf Add a new installed header - buffersrc.h
1067 It contains a new function av_buffersrc_buffer() that allows passing
1068 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
1069 it allows for direct rendering.
1070 1c9e340 Add avfilter_copy_frame_props() for copying properties from
1071 AVFrame to AVFilterBufferRef.
1072
1073 2011-12-25 - lavc 53.31.0
1074 Add the following new fields to AVFrame:

1091 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
1092 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
1093 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
1094 audio decoders to use get_buffer().
1095
1096 2011-12-04 - 560f773 - lavc 53.24.0
1097 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1117 AVCodecContext.internal_buffer --> AVCodecInternal.buffer
1118 AVCodecContext.internal_buffer_count --> AVCodecInternal.buffer_count
1119 AVCodecContext.is_copy --> AVCodecInternal.is_copy

1126 interrupt callbacks.
1127 6aa0b98 Add AVIOInterruptCB struct and the interrupt_callback field to
1128 AVFormatContext.
1129 1dee0ac Add avio_open2() with additional parameters. Those are
1130 an interrupt callback and an options AVDictionary.
1131 This will allow passing AVOptions to protocols after lavf
1132 54.0.
1133
1134 2011-11-06 - ba04ecf - lavu 51.14.0

1911
1912 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
1913 Remove the next field from AVFilter, this is not anymore required.
1914
1915 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1916 Introduce the avfilter_next() function.
1917
1918 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1919 Change the signature of avfilter_register() to make it return an
1920 int. This is required since now the registration operation may fail.
1921
1922 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1923 Make the pixdesc.h API public.
1924
1925 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1926 Add a next field to AVFilter, this is used for simplifying the
1927 registration and management of the registered filters.
1928
1929 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
1930 Add a description field to AVFilter.
1931
1932 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1933 Change the interface of avfilter_make_format_list() from
1934 avfilter_make_format_list(int n, ...) to
1935 avfilter_make_format_list(enum PixelFormat *pix_fmts).
1936
1937 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
1938 Make avfilter_get_video_buffer() recursive and add the w and h
1939 parameters to it.
1940
1941 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
1942 Add w and h fields to AVFilterPic.
1943
1944 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1945 This is now an unsigned int instead of a signed int.
1946
1947 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1948 Add a pts field to AVSubtitle which gives the subtitle packet pts
1949 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1950 not work right without this.
1951
1952 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1953 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1954 major version. Use AV_PKT_FLAG_KEY instead.
1955
1956 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1957 av_lockmgr_register() can be used to register a callback function
1958 that lavc (and in the future, libraries that depend on lavc) can use
1959 to implement mutexes. The application should provide a callback function
1960 that implements the AV_LOCK_* operations described in avcodec.h.
1961 When the lock manager is registered, FFmpeg is guaranteed to behave
1962 correctly in a multi-threaded application.
1963
1964 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1965 av_free_packet() is no longer an inline function. It is now exported.
1966
1967 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1968 Please use NULL instead. This has been supported since r16506
1969 (lavf > 52.23.1, lavc > 52.10.0).
1970
1971 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1972 The old decoding functions are deprecated, all new code should use the
1973 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1974 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1975 argument instead of a const uint8_t *buf / int buf_size pair.
1976
1977 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1978 Introduce the av_fifo_space() function.
1979
1980 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1981 Move AVPacket declaration from libavformat/avformat.h to
1982 libavcodec/avcodec.h.
1983
1984 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1985 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1986 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1987 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1988 PIX_FMT_BGR32_1 are now macros.
1989 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1990 Re-sort the enum PixelFormat list accordingly.
1991 This change breaks API/ABI backward compatibility.
1992
1993 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1994 Add the enum PixelFormat values:
1995 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1996 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1997
1998 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1999 The Mersenne Twister PRNG implemented through the av_random* functions
2000 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2001 instead.
2002
2003 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2004 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2005 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2006 and av_fifo_realloc2.
2007 In addition, the order of the function arguments of av_fifo_generic_read
2008 was changed to match av_fifo_generic_write.
2009 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2010 applications, they may not use sizeof() or directly access members.
2011
2012 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2013 Introduce a new metadata API (see av_metadata_get() and friends).
2014 The old API is now deprecated and should not be used anymore. This especially
2015 includes the following structure fields:
2016 - AVFormatContext.title
2017 - AVFormatContext.author
2018 - AVFormatContext.copyright
2019 - AVFormatContext.comment
2020 - AVFormatContext.album
2021 - AVFormatContext.year
2022 - AVFormatContext.track
2023 - AVFormatContext.genre
2024 - AVStream.language
2025 - AVStream.filename
2026 - AVProgram.provider_name
2027 - AVProgram.name
2028 - AVChapter.title
