192009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
20 av_lockmgr_register() can be used to register a callback function
21 that lavc (and in the future, libraries that depend on lavc) can use
22 to implement mutexes. The application should provide a callback function
23 the implements the AV_LOCK_* operations described in avcodec.h.
24 When the lock manager is registered FFmpeg is guaranteed to behave
25 correct also in a multi-threaded application.

342009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
35 The old decoding functions are deprecated, all new code should use the
36 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
37 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
38 argument instead of a const uint8_t *buf / int buf_size pair.

472009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
48 Make the pixel formats: PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
49 PIX_FMT_BGRA, which were defined as macros, defined as enum
50 PixelFormat values, and viceversa make PIX_FMT_RGB32,
51 PIX_FMT_RGB32_1, PIX_FMT_BGR32, PIX_FMT_BGR32_1 defined as macros.
52 Also make avcodec_get_pix_fmt() recognize the "rgb32" and "bgr32"
53 aliases.
f3370e14 54 Re-sort the enum PixelFormat list accordingly.

59 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
60 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

65 instead.

672009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
68 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
69 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
70 and av_fifo_realloc2.
71 In addition, the order of the function arguments of av_fifo_generic_read
72 were changed to match av_fifo_generic_write.
73 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
74 applications, they may not use sizeof() or directly access members.
