Hi Andrew

The patch should be platform neutral.

If something is looping still, that suggests you are still streaming 
with the other encoder at the same time. And looping suggests the stream 
broadcaster is looping as well. I normally see a stream run then stop.

Silly question time: are you publishing to a proper "live" entrypoint? 
Or to an "ondemand" entrypoint (which doesn't really exist)? Your 
playback URLs will look like these for live:

live - rtmp://cpNNNNN.live.edgefcs.net/live/myprov@1234

while the entrypoints will be


You could always provision a new stream from Akamai. You can have as 
many as you like, I believe. What does your Akamai control panel tell you?
