833 correctly in a multi-threaded application.

844 new functions avcodec_decode_video2(), avcodec_decode_audio3() and

227d1b98
DB
856 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
857 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
858 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
859 PIX_FMT_BGR32_1 are now macros.
860 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.

227d1b98 879 was changed to match av_fifo_generic_write.
