15 20090308 - r17869 - lavu 50.0.0 - AVFifoBuffer
16 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped and replaced
17 by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write and av_fifo_realloc2.
18 In addition, the order of the function arguments of av_fifo_generic_read were changed
19 to match av_fifo_generic_write.
20 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by applications,
21 they may not use sizeof() or directly access members.
