Reimplemented from UFunctionCamBase.

References createBaseVar().

virtual bool UFuncV4lGst::handleCommand ( UServerInMsg *  msg, void *  extra  )

stream thread assembles processing and starts gstreamer main thread, This part works, use client script to test.

Returns

when main loop is stopped, or an error occured.
