[Live-devel] Is it possible to override the RTP port chosen by the server?

FYI, I had to undo the change to the code that I made (back in version 2012.06.12) to ignore server-specified SDP port numbers (for unicast streams), because it was breaking our SIP client.

Now, if you want the code to ignore SDP-specified port numbers, you can do so by adding
	-DIGNORE_UNICAST_SDP_PORTS=1
to the compile line (when compiling "liveMedia/MediaSession.cpp").

(Even better, though, would be to get Samsung to upgrade their cameras' firmware to allow their port number(s) to be configured by the user.)
