[Live-devel] Problem of new support for unicast RTSP/RTP streaming from a single input source

Mike,

This was a problem with MPEG-4 video sources.  It was caused by the fact 
that the server needs to read from the input stream twice: Once to read the 
first "VisualObjectSequence" header (to set the SDP "config" string), and 
again for the actual streaming to the client.

Other kinds of data source (e.g., MP3, MPEG-1 or 2 video) didn't seem to 
have a problem.

I have now installed a new version (2004.10.07) of the code that should fix 
this problem.  (Note, though, that - for MPEG-4 video sources - a 
"VisualObjectSequence" header must occur periodically in the stream.  It's 
not enough to just have one at the beginning of the stream, but nowhere else.
