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

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

942 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
943 it allows for direct rendering.
944 1c9e340 Add avfilter_copy_frame_props() for copying properties from
945 AVFrame to AVFilterBufferRef.
946
947 2011-12-25 - lavc 53.31.0

965 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
966 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
967 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
968 audio decoders to use get_buffer().
969
970 2011-12-04 - 560f773 - lavc 53.24.0
971 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1820
1821 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1822 Add a pts field to AVSubtitle which gives the subtitle packet pts
1823 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1824 not work right without this.
1825
1826 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1827 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1830 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1831 av_lockmgr_register() can be used to register a callback function
1832 that lavc (and in the future, libraries that depend on lavc) can use
1833 to implement mutexes. The application should provide a callback function
1834 that implements the AV_LOCK_* operations described in avcodec.h.
1835 When the lock manager is registered, FFmpeg is guaranteed to behave
1836 correctly in a multi-threaded application.
1837
1838 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1839 av_free_packet() is no longer an inline function. It is now exported.
1840
1841 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1842 Please use NULL instead. This has been supported since r16506

1844
1845 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1846 The old decoding functions are deprecated, all new code should use the
1847 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1848 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1849 argument instead of a const uint8_t *buf / int buf_size pair.
1850
1851 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()

1858 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1859 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1860 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1861 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1862 PIX_FMT_BGR32_1 are now macros.
1863 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1864 Re-sort the enum PixelFormat list accordingly.
1865 This change breaks API/ABI backward compatibility.
1866
1867 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1868 Add the enum PixelFormat values:
1869 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1870 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1871
1872 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1873 The Mersenne Twister PRNG implemented through the av_random* functions
1874 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1875 instead.
1876
1877 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1878 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped

1881 In addition, the order of the function arguments of av_fifo_generic_read
1882 was changed to match av_fifo_generic_write.
