It worked fine, I could view the camera in mplayer. But, however, when I went to move the camera, I unplugged it and forgot to close mplayer. I didn't notice, moved it, plugged it back in and immediately Mplayer died and dropped a genaral protection fault oops + stacktrace in the kernel log. I unplugged the camera again, and the entire system froze, most likely a kernel panic. I've reproduced this twice, however I haven't been able to get it to occur when using mplayer from the command line (so that I can see what happens when it freezes). I've uploaded the 2 dmesg logs here: http://www.alex-smith.me.uk/files/dmesg.log http://www.alex-smith.me.uk/files/dmesg2.log and also my .config here: http://www.alex-smith.me.uk/files/config-2.6.23-rc5.txt The mplayer command I used: mplayer -cache 128 -tv driver=v4l:width=640:height=480:outfmt=i420:device=/dev/video1 -vc rawi420 -vo xv tv:// Thanks, Alex -- Alex Smith - http://www.alex-smith.me.uk - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
