[gst-devel] Strange behaviour

I'm having problems with some gstreamer plugins: the video is rendered 
only at the begin and then it freeze. I get this problems with rtpmp4v*, 
with tcpserversink/tcpclientsrc I have a similar problem but after some 
seconds the freeze disappears.
Take a look at this:
