[Live-devel] SETUPrtsp for two different IP

Sat Oct 1 00:51:52 PDT 2011

hi,

For our work we are trying to stream a mp4 container with two movie track on it, but from two different IP (using only one streaming server and two interface). 
When we stream our MP4 container we get this with wireshark:

Can you please tell us, what we can do to change the SETUPrtsp to indicate that the two track come from two different IP (interface) for example:
