1) Have you got "bttv" related modules installed (by "modprobe bttv")? You can use "lsmod" to check out. 2) Why don't you use "xawtv" for a test first? It's so easy and convenient. Charlie X.

Hello! I'm using a Logitech Quickcam Zoom, kernel 2.4.20, PWC v 8.10. A) I can cat /dev/video0 no problem, and pipe output to a file, what format is the data in and could it be useful in any way? B) videodog: ioctl VIDIOCMCAPTURE: Invalid argument C) vgrabbber: unable to find a supported capture format D) streamer -o hi.ppm: no grabber device available As you can see, I'm trying many command line applications to test video grabbing (No, don't have X and don't want it) however nothing seems to work except cat /dev/video0 > file I can see that the ascii spat at TTY during cat /dev/video0 changes as I move the camera around, it seems to be working at least in that mode.. Anyone have any hints? I haven't had a single third party app grab anything as of yet. Thank you - Steve Host
