AÖ		 8302009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
831 av_lockmgr_register() can be used to register a callback function
832 that lavc (and in the future, libraries that depend on lavc) can use
833 to implement mutexes. The application should provide a callback function
227d1b98
DB		 834 that implements the AV_LOCK_* operations described in avcodec.h.
835 When the lock manager is registered, FFmpeg is guaranteed to behave
836 correctly in a multi-threaded application.

RB		 8452009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
846 The old decoding functions are deprecated, all new code should use the
847 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
848 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
849 argument instead of a const uint8_t *buf / int buf_size pair.

5a43bbc3 8582009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
227d1b98
DB		 859 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
860 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
861 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
862 PIX_FMT_BGR32_1 are now macros.
863 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
f3370e14 864 Re-sort the enum PixelFormat list accordingly.
5a43bbc3
SS		 865 This change breaks API/ABI backward compatibility.
866
dd3bbb49
SS		 8672009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
868 Add the enum PixelFormat values:
869 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
870 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

c8f742ca
DB		 873 The Mersenne Twister PRNG implemented through the av_random* functions
874 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
875 instead.
876

DB		 8772009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
878 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
879 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
880 and av_fifo_realloc2.
881 In addition, the order of the function arguments of av_fifo_generic_read
227d1b98 882 was changed to match av_fifo_generic_write.
889cdae8
DB		 883 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
884 applications, they may not use sizeof() or directly access members.
22d4f236 885
889cdae8
DB		 8862009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
887 Introduce a new metadata API (see av_metadata_get() and friends).
888 The old API is now deprecated and should not be used anymore. This especially
429d6b21 889 includes the following structure fields:
