222009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
23 The old decoding functions are deprecated, all new code should use the
24 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
25 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
26 argument instead of a const uint8_t *buf / int buf_size pair.

352009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
36 Make the pixel formats: PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
37 PIX_FMT_BGRA, which were defined as macros, defined as enum
38 PixelFormat values, and viceversa make PIX_FMT_RGB32,
39 PIX_FMT_RGB32_1, PIX_FMT_BGR32, PIX_FMT_BGR32_1 defined as macros.
40 Also make avcodec_get_pix_fmt() recognize the "rgb32" and "bgr32"
41 aliases.
f3370e14 42 Re-sort the enum PixelFormat list accordingly.

552009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
56 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
57 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
58 and av_fifo_realloc2.
59 In addition, the order of the function arguments of av_fifo_generic_read
60 were changed to match av_fifo_generic_write.
61 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
62 applications, they may not use sizeof() or directly access members.
