the original idea of skipping one unmatching buffer when one needs to be
allocated from the buffer pool isn't that bad, but when the output
plugin can only provide few buffers (e. g. xxmc supports only 8 on most
devices) even this single buffer must be used to not trigger the frame
The attached patch enables this feature only when there is a total of
more than 8 buffers.
