6792009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
680 The old decoding functions are deprecated, all new code should use the
681 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
682 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
683 argument instead of a const uint8_t *buf / int buf_size pair.

227d1b98
DB
693 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
694 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
695 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
696 PIX_FMT_BGR32_1 are now macros.
697 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
f3370e14 698 Re-sort the enum PixelFormat list accordingly.

712 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
713 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
714 and av_fifo_realloc2.
715 In addition, the order of the function arguments of av_fifo_generic_read
227d1b98 716 was changed to match av_fifo_generic_write.

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