>> The strange thing is that, after rtspsrc, the track with payload 14 (according to the rtsp SDP media session) is supposed to have "media=audio", but somehow the rtsp pipe thinks it is "media=video payload=14 encoding-name=H.264). Thus, I think the whole capfilter things are messed up. I am totally lost here. Any pads here for rtspsrc? Please help!.

Actually this pipeline works ...
Why does gather bzbz's uri fail ? How come the 2 tracks caps are the 
same except for payload ?
Gather, what rtsp server do you use ? Could you send the sdp ?
