Webcam
The webcam in T61 is some sort of UVC camera: Found UVC 1.00 device Integrated Camera (17ef:1004). The module loads out of the box. I tested the camera using: Luvcview: http://mxhaard.free.fr/spca50x/Investigation/uvc/luvcview-20070512.tar.gz Just compile and run using ./luvcview -f yuv (JPG format doesn’t work)
I also tried gqcam and webcam, but both doesn’t work (first SEGFAULTs, second prints Invalid argument)
luvcview has a button to take pictures. Place your mouse over the buttons at the bottom of the window, and their function is revealed in the title bar. Unfortunately, the button for avi capture does not seem to work (although it does tell you what the video framerate is, which is helpful).
To capture a video stream, run ./luvcview -f yuv -S To play back the video stream, run mplayer -demuxer rawvideo -rawvideo fps=7:w=320:h=240:yuy2 stream.raw
