16 Add a JACK input device.

19 Introduce the av_fifo_space() function.
21 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
22 Move AVPacket declaration from libavformat/avformat.h to
25 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
26 Add the enum PixelFormat values:
27 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
28 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
30 2009-03-21 - r18116 - lavu 50.2.0 - av_random*
31 The Mersenne Twister PRNG implemented through the av_random* functions

36 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
37 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
38 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
40 In addition, the order of the function arguments of av_fifo_generic_read
41 were changed to match av_fifo_generic_write.
42 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
