Martin,

I haven't looked at your code in detail, because I first want to clarify 
what you're trying to do.  In particular, do you really want to stream from 
multiple cameras to the same multicast address and port?  Because that's 
what your code appears to do.  (It uses a single "rtpGroupsock", which will 
send to a single, specific (multicast address,port).)

If you really want to stream from multiple cameras to the same (multicast 
address,port), then - depending on which media player client you use - it's 
not surpising that the video from multiple cameras will 'overlap'.  (The 
only alternative is to pop up a separate window for each incoming video 
source, but most media players don't do that.)

If, instead, you want to stream to different (multicast address,port)s - 
one for each camera - then you will need to create separate 'groupsock' 
objects for each.
