Like try: gst-launch-0.10 -v mfw_v4lsrc ! fakesink And see if data is captured and see what format etc.. You'll see messages each time a buffer is received in fakesink. Then add the encoder gst-launch-0.10 -v mfw_v4lsrc ! mfw_vpuencoder width=176 height=144 codec-type=std_h263 ! fakesink And so on. If you can establish that data is flowing to udpsink you might want to check with wireshark if stuff goes over the network. Then on the receiver you can start with gst-launch -v udpsrc .. ! fakesink And slowly build the complete pipelines. This should give you an idea when things stop working.
