[gst-devel] help needed to write rtsp client using gstreamer plugins

[sanjay kumar gupta]

Hi Wim,
  Though bug for playbin with rtsp url issue is fixed with latest gstreamer/plugins code, I thought to play the same url using individual plugins elements using the following command but never succeeded. 
$gst-launch-0.10 rtspsrc location=rtsp://192.168.1.225/sample_50kbit.3gp ! rtpmp4vdepay ! decodebin ! xvimagesink sync=0
sometime window appear for fraction of second but it disappear. 
am I missing some elements to add in this to play video?
here is the log for this command:
-----------
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
