[gst-devel] video over network examples

[Chris Bare]

I'm trying to come up with a gst-launch command to send video from one machine
to another over the network. I tried the following:

server
gst-launch-0.10 -v -m -t v4lsrc device=/dev/video0 !  "video/x-raw-yuv,width=320,height=240,framerate=300/16" ! theoraenc quality=5 ! tcpserversink

client
gst-launch-0.10 -v -m -t tcpclientsrc !  xvimagesink

and they connected, but the client errored out with:
Got Message from element "tcpclientsrc0" (state-changed): GstMessageState,
old-s
tate=(GstState)GST_STATE_PAUSED, new-state=(GstState)GST_STATE_PLAYING,

I tried adding "video/x-raw-yuv,width=320,height=240,framerate=300/16" on the
client side before xvimagesink, but that didn't help.

Any suggestions?
