f988ce6c
1001 av_lockmgr_register() can be used to register a callback function
1002 that lavc (and in the future, libraries that depend on lavc) can use
1003 to implement mutexes. The application should provide a callback function
227d1b98
DB
1004 that implements the AV_LOCK_* operations described in avcodec.h.
1005 When the lock manager is registered, FFmpeg is guaranteed to behave
1006 correctly in a multi-threaded application.

RB
1016 The old decoding functions are deprecated, all new code should use the
1017 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1018 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1019 argument instead of a const uint8_t *buf / int buf_size pair.

227d1b98
DB
1029 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1030 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1031 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1032 PIX_FMT_BGR32_1 are now macros.
1033 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
f3370e14 1034 Re-sort the enum PixelFormat list accordingly.

1044 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1045 instead.

1049 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1050 and av_fifo_realloc2.
1051 In addition, the order of the function arguments of av_fifo_generic_read
227d1b98 1052 was changed to match av_fifo_generic_write.

1053 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1054 applications, they may not use sizeof() or directly access members.
