192009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
20 The old decoding functions are deprecated, all new code should use the
21 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
22 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
23 argument instead of a const uint8_t *buf / int buf_size pair.

322009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
33 Make the pixel formats: PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
34 PIX_FMT_BGRA, which were defined as macros, defined as enum
35 PixelFormat values, and viceversa make PIX_FMT_RGB32,
36 PIX_FMT_RGB32_1, PIX_FMT_BGR32, PIX_FMT_BGR32_1 defined as macros.
37 Also make avcodec_get_pix_fmt() recognize the "rgb32" and "bgr32"
38 aliases.
f3370e14 39 Re-sort the enum PixelFormat list accordingly.

522009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
53 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
54 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
55 and av_fifo_realloc2.
56 In addition, the order of the function arguments of av_fifo_generic_read
57 were changed to match av_fifo_generic_write.
58 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
59 applications, they may not use sizeof() or directly access members.
