22 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
23 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
24 and av_fifo_realloc2.
25 In addition, the order of the function arguments of av_fifo_generic_read
26 were changed to match av_fifo_generic_write.
27 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
28 applications, they may not use sizeof() or directly access members.
