As stated, all I can base my opinion on is the number of problem reports I've received. The VX-7000 is supposed to be UVC compatible but doesn't implement quite a few basic UVC requests (fortunately the driver works around the problem). I'm thus pretty sure it has never been tested with Linux during the development process, and I wouldn't be on its quality. The picture quality is a completely different story, I have no information about that. After some googling I also found out that the VX-6000 is not UVC compatible. > I've been watching out for an affordable 1.3 Mpixel webcam for a while > now, and I always thought the VX-6000 was a decent uvc-supported > candidate...

Do you have hints that this camera is capable of > 1280x1...@30fps? Frame rates usually decrease with the resolution. The limiting factor is quite often not USB bandwidth (as MJPEG compression would allow to stream 1280x1...@40fps quite easily over a USB 2.0 link) but sensor capabilities. Without looking at the camera UVC descriptors I can't tell what frame rates it really supports at 1280x1024, but I don't expect more than 15fps (if not 10fps). -- Regards, Laurent Pinchart _______________________________________________ Linux-uvc-devel mailing list [email protected] https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
