This seems to break things

cvlc --play-and-exit ~/videos/stream2962.ts --sout="#rtp{dst=127.0.0.1,port=4414,sdp=rtsp://127.0.0.1:9180/test.sdp, mux=ts}" >  /tmp/log.1 2> /tmp/log.2 & ./ffmpeg -i rtp://127.0.0.1:4414 -t 1 -bitexact -y out2962.avi

before this patch
frame=   14 fps=0.0 q=2.0 Lsize=      38kB time=00:00:01.00 bitrate= 309.2kbits/s speed= 117x    
video:32kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 19.610027%

after:
rtp://127.0.0.1:4414: Invalid argument
