Gstreamer issue on mac osx

[Gerard Toonstra]

Hi there,

I have an IP cam that is configured to output UDP multicast. I'm getting video on Ubuntu Linux (12.10), but on Mac OSX there are issues.
See here the output of two consecutive runs. The first one hangs, is aborted. The second one reports a "subclass rejected caps" issue,
resulting in failure to negotiate.

Does anyone know what the problem could be?  Missing libraries, incorrect versions?

I installed gstreamer from here:

http://docs.gstreamer.com/display/GstSDK/Installing+on+Mac+OS+X

Running Mountain Lion on Mac OSX mini: 12.2.0 Darwin Kernel Version 12.2.0
