I have SuSE 7.2 and I have updated to the official SuSE kernel 2.4.7. I am trying to configure my web cam Philips TouCam USB. I load the modules and all work fine with options size=qsif y fps=30 but when I run xawtv I can not see nothing.
The output from xawtv is:
x11: 1024x768, 16 bit/pixel, 2048 byte/scanline, DGA /dev/video: no overlay support v4l-conf had some trouble, trying to continue anyway
Harmless - my Phillips webcam says that too. <snip VIDIOCGAUDIO warnings> Those are harmless too. It's saying it can't open the sound device of the webcam.
Invalid argument ioctl: VIDIOCMCAPTURE(0,fmt=0,size=0x0): Device or resource busy
This appears to be the root of the problem. Something else has claimed the capture device (the webcam). Check your process table, or try fuser on /dev/video.
