[gst-devel] Problem in gstrtpbin and AV Transfer---Urgent

I have figured out the reason for the Video not getting updated.
The reason in that the encoder doesn't encode the incoming data until the
TimeStamp on the incoming data is not more then the timeStamp on the last
Here when i start file transfer then the timestamp is reset at the filesrc
and it starts from 0.
So it doesn't give any encoded fame until the timestamp is not greater that
the last timestamp of the frame encoded with the V4l2src.
Now similar problem is faced when i switch back to the camera from File.
Please give some hints to resolve the same.
This will be very helpful
Thanks a lot
