AÖ		 7662009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
767 av_lockmgr_register() can be used to register a callback function
768 that lavc (and in the future, libraries that depend on lavc) can use
769 to implement mutexes. The application should provide a callback function
227d1b98
DB		 770 that implements the AV_LOCK_* operations described in avcodec.h.
771 When the lock manager is registered, FFmpeg is guaranteed to behave
772 correctly in a multi-threaded application.

RB		 7812009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
782 The old decoding functions are deprecated, all new code should use the
783 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
784 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
785 argument instead of a const uint8_t *buf / int buf_size pair.

227d1b98
DB		 795 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
796 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
797 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
798 PIX_FMT_BGR32_1 are now macros.
799 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
f3370e14 800 Re-sort the enum PixelFormat list accordingly.
5a43bbc3
SS		 801 This change breaks API/ABI backward compatibility.

814 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
815 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
816 and av_fifo_realloc2.
817 In addition, the order of the function arguments of av_fifo_generic_read
227d1b98 818 was changed to match av_fifo_generic_write.
889cdae8
DB		 819 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
820 applications, they may not use sizeof() or directly access members.
