mpeg2ts won't playback

[Rand Graham]

Hello all,

I am trying to playback an mpeg2 TS that is being sent via udp to the loopback interface.

The video doesn't playback. I get a blank video window. I don't get much information on what the problem might be.

When setting  GST_DEBUG to 3. I see a FIXME that says something about a "Refcounting issue"

Can someone tell me why gstreamer is unable to play this back?
