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! --fred
