That's interesting, as I just had to write an element to buffer up the
188 byte packets from mpegtsmux in order to feed a v4l2 driver that
feeds a hardware decoder.  My observation was that the mpegtsmux was
always pushing a single packet at a time.  I had intended to use
v4l2sink but it wasn't buffering the data at all and there were too
many QBUF exchanges for the driver to keep up working 1 packet at a
time.

How are you getting mpegtsmux to buffer the packets before pushing?  I
wonder if it's how mpegtsmux is being fed data...
