I've been trying to get an approved USB webcam (Creative Optia AF) to run
using GStreamer and sending the output to an XWindow and I keep getting
I have the uvcvideo module loaded and /dev/video0 is present.
I am running openembedded on the Gumstix Verdex Pro XL6P. Could it be that
the camera is USB 2.0 and the Verdex Pro is only rated for USB 1.1?
This is what I see when I plug the camera in...
root at gumstix-custom-verdex:~# usb 1-2: new full speed USB device using
pxa27x-ohci and address 4
usb 1-2: configuration #1 chosen from 1 choice
uvcvideo: Found UVC 1.00 device VF0560 Live! Cam Optia AF (041e:406d)
input: VF0560 Live! Cam Optia AF as
4:3:1: cannot get freq at ep 0x84
When I try to gst-launch with the v4lsrc or v4l2src elements and I get the
error below. I have tried a variety of settings using the 'video/x-raw-rgb'
cap but I always get the same error. The videotestsrc element works fine

Any help would be greatly appreciated...
