[Live-devel] Multicast to RTSP

Don't forget to also set the "reuseFirstSource" variable to "True".

Note, you don't need to use "cat" here.  Instead, use
	testOnDemandRTSPServer < file.ts

Does the following work:

mcast2stdout > test.ts
testOnDemandRTSPServer (using the original, unmodified code)

If not, then there's a problem with your "mcast2stdout" application.

If this does work, then try the following:

mcast2stdout > file.ts
testOnDemandRTSPServer < file.ts (using your new, modified code)

No.  If the incoming data really is MPEG Transport Stream data, then 
you should be able to pipe it directly into your modifiled 
"testOnDemandRTSPServer".
