ffmpeg->rtp

Having trouble with the swarm & choppy video.

Starting at the top, we throw this to janus:
/opt/ffmpeg/bin/ffmpeg -ss 00:00:00 -re -i file:///usr4/mydetv/webm/archive.org/Drive-inIntermission2/Drive-inIntermission2.ogv.vp8-opus.webm -vcodec copy -an -f rtp rtp://10.11.1.96:5024 -acodec copy -vn -f rtp rtp://10.11.1.96:5022

on mac, play file:
ffplay -protocol_whitelist “file,rtp,udp” -i /private/nfs/a6/usr6/mydetv/webm/clips/fireworks.mp4.vp8-opus.webm -strict -2
not choppy

/opt/ffmpeg/bin/ffmpeg -re -i /usr4/mydetv/webm/archive.org/TarzanoftheApes1918AndyDivx_512kb.mp4.vp8-opus.webm -vcodec copy -an -f rtp rtp://10.11.1.96:5124 -acodec copy -vn -f rtp rtp://10.11.1.96:5122
