Hi Wim, Thanks for the quick reply. I fixed the width and height to be the same. Now it just sits there after going to playing state. Cpu utilization is about 10 percent. I expected it to open a window for ximagesink, but it does not. I see some strange caps: /GstPipeline:pipeline0/GstRtpVRawDepay:rtpvrawdepay0.GstPad:src: caps = video/x-raw-rgb, width=(int)400, height=(int)300, format=(fourcc)0x00000000, framerate=(fraction)0/1 The framerate is 0, despite the fact that I set it to 10. Thanks again, Bert Douglas <div class="gmail_quote">On Fri, Sep 3, 2010 at 11:47 AM, Wim Taymans <<a href="mailto:wim.taymans@gmail.com">wim.taymans@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> <div class="im">On Fri, 2010-09-03 at 11:35 -0500, Bert Douglas wrote: > I followed Wim's very helpful advice.

The crash is because of a bug in the depayloader (fixing now).
