Comment (by Cigaes):
If your change makes the error disappear after the filters but reappears
within libavfilter, then it is not an enhancement at all, probably the
opposite. This is exactly what is happening here: the error means that
frames were accumulating in the muxing buffer after filtering and (dummy)
encoding, now they are accumulating in buffersink. It seems to work better
because buffersink does not have a limit, but the frames are still
accumulating. Even worse, since they are accumulating in libavfilter, they
are accumulating as real frames, not encoded packets, possibly immensely
larger.
It is my belief that the scheduling in libavfilter is now mostly correct
and that the problem lies after libavfilter.
