Comment (by thilo.borgmann):
Thanks for your patch, mateo!
If you extend your buffer size to way bigger than 4 frames you should be
able to see if your assumptions are correct and we just do not consume the
frames fast enough (and your buffer warning occurs later).
Otherwise, if there is something out of sync on the system-side, your
buffering extension could be useless and memory requirements raise. In
that case we have to figure out if we can somehow acquire these missing
frames in any way or if we don't even have a chance.
I'm eager to hear feedback on the patch from LordHDL.
