Comment (by caseynielson):
Not fixed, ffmpeg continues to produce packets of inconsistent length.
Used the following command line:
ffmpeg -i
'udp://232.70.2.11:1234?source=172.31.22.135&fifo_size=1000000&overrun_nonfatal=1'
-acodec copy -vcodec copy -f mpegts udp://232.70.33.1:1234?pkt_size=1316
Built from source today.
