Use pix_buffer to grab a single frame and then key that if you really
only want a single frame every once and a while.  If you want to
key every frame of the live feed then just put that into pix_chroma_key.<br><br><div><span class="gmail_quote">On 4/19/06, <b class="gmail_sendername">Jonathan Goodwin</b> &lt;<a href="mailto:jonathan@jgoodwin.co.uk">jonathan@jgoodwin.co.uk
