302009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
31 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
32 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
33 and av_fifo_realloc2.
34 In addition, the order of the function arguments of av_fifo_generic_read
35 were changed to match av_fifo_generic_write.
36 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
37 applications, they may not use sizeof() or directly access members.
