[gst-devel] Lip Sync issues with gstrtpbin

[Manish Rana]

In addition to the problem faced by Rahul, I am also getting delay in RTP
packets
When i am transmitting and receiving the packets between two device
connected through USB i am getting delay of more then 1 sec, in case of
audio ( alone , no video is there. )
I am using the latest gstreamer packeges.
