hi.
i finally stole a webcam (Logitech QuickCam Pro 4000) from a Windows box
and stuck it into the USB port of as newly rebuilt Fedora C2 machine.
i do have pwc module on my system. but when i try and view with either
xawtv --device /dev/video0 or with VIC i get solid black with xawtv and
'green' with VIC/VideoService or VIC/VideoProducerService.
xawtv gives me a bunch of:
ioctl: VIDIOCMCAPTURE(frame=0;height=120;width=160;format=5): Invalid argument
ioctl: VIDIOCMCAPTURE(frame=0;height=120;width=160;format=4): Invalid argument
ioctl: VIDIOCMCAPTURE(frame=0;height=120;width=160;format=1): Invalid argument
ioctl: VIDIOCMCAPTURE(frame=0;height=120;width=160;format=13): Invalid argument
and VIC gives me trillions of:
ioctl VIDIOMCAPTURE: Invalid argument
ioctl VIDIOCSYNC: Invalid argument
ioctl VIDIOMCAPTURE: Invalid argument
ioctl VIDIOCSYNC: Invalid argument
ioctl VIDIOMCAPTURE: Invalid argument
ioctl VIDIOCSYNC: Invalid argument
ioctl VIDIOMCAPTURE: Invalid argument
etc.
i rebuilt and installed the kernel modules with a newer version of pwc,
pwc-9.0.2, hoping that that might fix the problem. it didn't.
does anyone see an obvious issue here that i'm missing?
i don't understand what is going on with ioctl.
can anyone suggest actions i might try in order to isolate and destroy
this problem?
thanks!
