Hey,
I have a schleptop with a built-in camera (lenovo t400). Xawtv works
great, but I cannot get pix_video to start.
When I start it (trying out lots of different options), it says:
VIDIOCSCHAN: Invalid argument
Anyone have an idea how to fix Pixes/videoV4L.cpp so that it makes
the right ioctls?
thanks -august.
Here is my v4linfo:
