793 have been accessed from outside of lavc
794 * qscale_table, qstride, qscale_type, mbskip_table, motion_val,
795 mb_type, dct_coeff, ref_index -- mpegvideo-specific tables,
796 which are not exported anymore.

906 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
907 Note that this can break user code that includes avcodec.h and uses the
908 'CodecID' identifier. Such code should either #undef CodecID or stop using the
909 CodecID name.

969 For audio formats with fixed frame size, the last frame
970 no longer needs to be padded with silence, libavcodec
971 will handle this internally (effectively all encoders
972 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

1064 f1caf01 Allow doing av_write_frame(ctx, NULL) for flushing possible
1065 buffered data within a muxer. Added AVFMT_ALLOW_FLUSH for
1066 muxers supporting it (av_write_frame makes sure it is called

1086
1087 2011-12-25 - lavfi 2.14.0
1088 e1d9dbf Add a new installed header - buffersrc.h
1089 It contains a new function av_buffersrc_buffer() that allows passing
1090 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
1091 it allows for direct rendering.
1092 1c9e340 Add avfilter_copy_frame_props() for copying properties from
1093 AVFrame to AVFilterBufferRef.
1094
1095 2011-12-25 - lavc 53.31.0
1096 Add the following new fields to AVFrame:

1113 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
1114 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
1115 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
1116 audio decoders to use get_buffer().
1117
1118 2011-12-04 - 560f773 - lavc 53.24.0
1119 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1939
1940 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1941 Change the signature of avfilter_register() to make it return an

1945 Make the pixdesc.h API public.

1952 Add a description field to AVFilter.
1953
1954 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1955 Change the interface of avfilter_make_format_list() from
1956 avfilter_make_format_list(int n, ...) to
1957 avfilter_make_format_list(enum PixelFormat *pix_fmts).
1958
1959 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
1960 Make avfilter_get_video_buffer() recursive and add the w and h
1961 parameters to it.
1962
1963 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic

1965
1966 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1967 This is now an unsigned int instead of a signed int.
1968
1969 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1970 Add a pts field to AVSubtitle which gives the subtitle packet pts
1971 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1972 not work right without this.
1973
1974 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1975 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1976 major version. Use AV_PKT_FLAG_KEY instead.
1977
1978 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1979 av_lockmgr_register() can be used to register a callback function
1980 that lavc (and in the future, libraries that depend on lavc) can use
1981 to implement mutexes. The application should provide a callback function
1982 that implements the AV_LOCK_* operations described in avcodec.h.
1983 When the lock manager is registered, FFmpeg is guaranteed to behave
1984 correctly in a multi-threaded application.
1985
1986 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1987 av_free_packet() is no longer an inline function. It is now exported.
1988
1989 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1990 Please use NULL instead. This has been supported since r16506
1991 (lavf > 52.23.1, lavc > 52.10.0).
1992
1993 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1994 The old decoding functions are deprecated, all new code should use the
1995 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1996 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1997 argument instead of a const uint8_t *buf / int buf_size pair.
1998
1999 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2000 Introduce the av_fifo_space() function.
2001
2002 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2003 Move AVPacket declaration from libavformat/avformat.h to
2004 libavcodec/avcodec.h.
2005
2006 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2007 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2008 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2009 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2010 PIX_FMT_BGR32_1 are now macros.
2011 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2012 Re-sort the enum PixelFormat list accordingly.
2013 This change breaks API/ABI backward compatibility.
2014
2015 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2016 Add the enum PixelFormat values:
2017 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2018 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2019
2020 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2021 The Mersenne Twister PRNG implemented through the av_random* functions
2022 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2023 instead.
2024
2025 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2026 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2027 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2028 and av_fifo_realloc2.
2029 In addition, the order of the function arguments of av_fifo_generic_read
2030 was changed to match av_fifo_generic_write.
2031 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2032 applications, they may not use sizeof() or directly access members.
2033
2034 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2035 Introduce a new metadata API (see av_metadata_get() and friends).
2036 The old API is now deprecated and should not be used anymore. This especially
2037 includes the following structure fields:
2038 - AVFormatContext.title
2039 - AVFormatContext.author
2040 - AVFormatContext.copyright
2041 - AVFormatContext.comment
2042 - AVFormatContext.album
2043 - AVFormatContext.year
2044 - AVFormatContext.track
2045 - AVFormatContext.genre
2046 - AVStream.language
2047 - AVStream.filename
2048 - AVProgram.provider_name
2049 - AVProgram.name
2050 - AVChapter.title
