This is a modified version of Anton's earlier patchset [1].
The main changes are that the new FIFO API is a clean break with
the old API (the new API uses a new structure (called AVFifo)
instead of sharing AVFifoBuffer with the old API) and that it
is now documented that one may attempt to read/write more
from/to the FIFO than is currently possible and that such
an attempt leads to an error being returned. This allows to
replace loops of the form
while (av_fifo_size(fifo)) {
TYPE element;
av_fifo_generic_read(fifo, &element, sizeof(element), NULL);
// do something with element, typically: free it
}
by
TYPE element;
while (av_fifo_read(fifo, &element, 1) >= 0)
// do something with element
