Hi, The colors are completly wrong it looks like a color channel is missing or maybe switched. Are you sure this is not a graphic card issue ? Could you try disabling hardware acceleration: guvcview --hwd_acel=0 This prevents the use of hardware overlays, it decreases performance but could if the colors are OK it may signal a problem with you graphic card.
