Hi folks, I know I am a little behind, but i just upgraded my kernel to 2.6.27-16, and so I had to recompile the webcam drivers. And now it's not working.
Here's what I do: $ sudo mknod /dev/video0 c 81 0 $ sudo modprobe videodev $ sudo modprobe -v compat_ioctl32 $ sudo insmod sn9c20x.ko When I run $ mplayer tv:// -tv driver=v4l2:width=640:height=480:outfmt=i420:fps=30 I get MPlayer 1.0rc2-4.3.2 (C) 2000-2007 MPlayer Team CPU: Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz (Family: 6, Model: 15, Stepping: 6) CPUflags: MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1 Compiled with runtime CPU detection. mplayer: could not connect to socket mplayer: No such file or directory Failed to open LIRC support.
