[streaming] Multicast streaming and forward error correction...

Hello all.

I am working on a project where we are trying to stream several mpeg2
and 4 videos over a wireless network using multicast.  I have managed to
 devise a wireless network where I can get upwards of 24MBits/sec
multicast on the wireless link, but of course there is still packet loss.

Now that I have the bandwidth I need, my focus is shifting toward
forward error correction.  I know there is FEC built into the receiving
logic of vlc (for DVB), but how about for the sending?

Ideally, I would like to be able to tell vlc to stream with "--fec 10
- --fec-alg 2" that would correct for a 10% packet loss using algorithm 2,
etc.

Is there anything like this for streaming with vlc?

Any help at all would be appreciated, including any other help with
streaming multicast on a wireless link! :)
