[gst-devel] rtspsrc can't connect to network camera

[Kocsis Tibor]

Hi,

I have a network camera and i wan't to use rtspsrc to watch live, but
it can't connect to the camera. The last few lines are the following
before I have the "not linked (-1)" error message:

VLC and mplayer can work with the camera, only gstreamer fails. It is
possible to have some problem with the "PT 100"? For h264 the payload
is usually 96, but this camera sends the following sdp back:

Any ideas?

Thanks
