there was a patch, ive applied and fixed the worst of it
you can now prevent bursts with -packet_gap
What is missing now is to add either some -bandwidth option or even
better make udp use the bitrate or PCR/SCR to time the outputted udp
packets. Which would be nicer than the packet_gap based system
