If you would like to run a simple live preview demo on the Leopard Board, where the video captured by the Cam is displayed over the composite output. You run the following gstreamer pipeline:
gst-launch -e v4l2src always-copy=false ! dmaiaccel ! TIDmaiVideoSink sync=false displayStd=v4l2 displayDevice=/dev/video2
Remember to run the loadmodules.sh command on the Leopard Board before running any pipeline.
