I have no idea what the RTSP stream looks like for this camera. That post you referenced was for another brand with a really odd RTSP implementation (I haven't seen any other manufacturer do it that way since). I certainly hope this camera doesn't do what that camera did for RTSP.
Do you have a PDF version of the manual? If so, what does it say about RTSP support? Hopefully it lists out the full RTSP stream path. IE: rtsp://ipaddress:554/channel01.sdp
The specific RTSP path is what I'd need to confirm or add support for this camera. If you can post that here or send to firstname.lastname@example.org
I'll take a look.
FYI: MobiLinc certainly can stream multiple RTSP channels at a time. The camera may limit the number of connections, but MobiLinc shouldn't have any issues.
