Simple thing to try is to add a queue (thread) after the payloader, and
name is pay0 (even if it not a payloader, it should still work. That will
split the load of packetization (which will likely copy the stream) in its
own thread. That being said, adding buffer list support to this payloader,
and sub-buffer support may be required for such a high bitrate case.
