[Live-devel] Problem setting rtpmap on Flir A320 thermal camera.

[Michael Rahlff]

Dear Sirs.
I am having trouble trying to get a thermal camera (Flir A320) to stream the raw data.

My goal is to receive raw data from a Flir A320 (rtpmap 102 [See below output] ).

I have successfully connected to and streamed MPEG4 encoded video from the camera with VLC, but as mentioned, I need to change to rtpmap 102 to get the raw data instead.

I have downloaded “live555” and looked at testRTSPClient.cpp example, but cannot see where to set rtpmap.

Is it correct understanding, I need to make my own class and then inherence from the RTPSource class?

According to the Flir A320 manual, the transport format is as described in RFC4175 (RTP - payload format for uncompressed video)
