[Live-devel] RTP to RTCP for Helix

That's because VLC - when used as a RTP *transmitter* - uses a 
quick-and-dirty, custom implementation of RTP (*not* the "LIVE555 
Streaming Media" code) that does not include RTCP.  (VLC uses the 
LIVE555 code only when it is used as a receiver/player.)

Perhaps.  But it would be much better (and probably simpler) to use 
our own RTSP/RTP server implementation, with FFMPEG (e.g.) used as an 
encoder.
