Wow, that's really odd... because my machine has no /dev/video1 device. However, when entering /dev/video1 into the "Source:" field, then the Batch line updated to /dev/video0 !!! After that, it seems like it's trying to read from the device. If I try a 1 frame capture it pauses, then increments the frame counter in the "position" field. After a while I get "Frames Behind:" posted, and occasional error messages that end with "data_size=0"... I'm guessing it never read anything from the webcam. It still seems like the character device /dev/video0 is not open to me. Is this possible? Also, the webcam light never comes on. I have no idea if that's a problem or not... is the light just a decoration that most software turns on, or does it really imply that the device is grabbing/sending frames? If so, does just an "open()" on the device file start it, or must some command be written to start it up? Feel free to direct me to a USB programmer's list if that's where I need to be...
