1876 Change the signature of avfilter_register() to make it return an
1877 int. This is required since now the registration operation may fail.

1883 Add a next field to AVFilter, this is used for simplifying the
1884 registration and management of the registered filters.

1890 Change the interface of avfilter_make_format_list() from
1891 avfilter_make_format_list(int n, ...) to
1892 avfilter_make_format_list(enum PixelFormat *pix_fmts).

343bfdd3 19132009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
f988ce6c
1914 av_lockmgr_register() can be used to register a callback function
1915 that lavc (and in the future, libraries that depend on lavc) can use
1916 to implement mutexes. The application should provide a callback function
227d1b98
DB
1917 that implements the AV_LOCK_* operations described in avcodec.h.
1918 When the lock manager is registered, FFmpeg is guaranteed to behave
1919 correctly in a multi-threaded application.

2851d225
RB
1929 The old decoding functions are deprecated, all new code should use the
1930 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1931 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1932 argument instead of a const uint8_t *buf / int buf_size pair.

227d1b98
DB
1942 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1943 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1944 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1945 PIX_FMT_BGR32_1 are now macros.
1946 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
f3370e14 1947 Re-sort the enum PixelFormat list accordingly.

1961 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1962 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1963 and av_fifo_realloc2.
1964 In addition, the order of the function arguments of av_fifo_generic_read
227d1b98 1965 was changed to match av_fifo_generic_write.

1966 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1967 applications, they may not use sizeof() or directly access members.
