[FFmpeg-user] UDP FEC Protocol?

Recently heard a company was working on FEC for their streaming.  He 
also said they were building it as a proprietary system, so I guess 
they'll have it, and we won't.

But I assume FEC means a UDP-based streaming protocol.  Do we know of 
any such thing existing currently?

This has me intrigued.  Using the error counts coming out of the fec 
"layer" in a udp stream, maybe one could implement congestion avoidance, 
and downshift the bitrate of the stream dynamically.

So -- is there a streaming protocol that is udp/fec, potentially 
congestion-avoidant, and can be used for abr?
