Do most of Webcams have no RGB support? I'm not experienced on that. Does anybody know the percentage of RGB support by Webcams? -----Original Message----- From: Devin Heitmueller [mailto:[email protected]] Sent: Wednesday, February 03, 2010 11:19 AM To: Charlie X.

That only really works if the hardware supports providing RGB data as opposed to YUYV (which many do not). Or, it would work if you link against libv4l to do the conversion in userland.
