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.)
