754 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
755 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
756 Note that this can break user code that includes avcodec.h and uses the
757 'CodecID' identifier. Such code should either #undef CodecID or stop using the
758 CodecID name.

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

939 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
940 it allows for direct rendering.
941 1c9e340 Add avfilter_copy_frame_props() for copying properties from
942 AVFrame to AVFilterBufferRef.
943
944 2011-12-25 - lavc 53.31.0

963 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
964 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
965 audio decoders to use get_buffer().
966
967 2011-12-04 - 560f773 - lavc 53.24.0
968 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1817
1818 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1819 Add a pts field to AVSubtitle which gives the subtitle packet pts
1820 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1821 not work right without this.
1822
1823 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1824 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1827 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1828 av_lockmgr_register() can be used to register a callback function
1829 that lavc (and in the future, libraries that depend on lavc) can use
1830 to implement mutexes. The application should provide a callback function
1831 that implements the AV_LOCK_* operations described in avcodec.h.
1832 When the lock manager is registered, FFmpeg is guaranteed to behave
1833 correctly in a multi-threaded application.
1834
1835 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1836 av_free_packet() is no longer an inline function. It is now exported.
1837
1838 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1839 Please use NULL instead. This has been supported since r16506

1841
1842 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1843 The old decoding functions are deprecated, all new code should use the
1844 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1845 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1846 argument instead of a const uint8_t *buf / int buf_size pair.
1847
1848 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()

1854
1855 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1856 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1857 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1858 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1859 PIX_FMT_BGR32_1 are now macros.
1860 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1861 Re-sort the enum PixelFormat list accordingly.
1862 This change breaks API/ABI backward compatibility.
1863
1864 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1865 Add the enum PixelFormat values:
1866 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1867 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1868
1869 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1870 The Mersenne Twister PRNG implemented through the av_random* functions
1871 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1872 instead.
1873
1874 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1875 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1876 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1877 and av_fifo_realloc2.
1878 In addition, the order of the function arguments of av_fifo_generic_read
1879 was changed to match av_fifo_generic_write.
1880 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1881 applications, they may not use sizeof() or directly access members.
