[gst-devel] Video Streaming over network

[Pavan Kumar Patale]

Hi,

I am just trying to build simple video streaming application using GStreamer 
framework.
The idea is to stream video from my IBM PC webcam to another computer which 
is connected
via LAN.  To start with i have build following pipelines and tried to stream 
in the localhost itself.
But i am getting an error in the terminal 2.

Can some one pls throw some light on this error.   Is the usage right ?

Thanks,
Pavan.



In Terminal 1:-
---------------
[pavan at localhost ~]$ gst-launch-0.10 v4lsrc ! ffmpegcolorspace ! 
tcpserversink
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...

In Terminal 2:-
--------------------
[pavan at localhost ~]$ gst-launch-0.10 tcpclientsrc  ! xvimagesink
