Hello, I'm running kernel 2.4.7-10 with bttv2 (20020219) and trying to write a capture routine for a project. My problem is that the following ioctls fail: VIDIOC_G_FREQUENCY VIDIOC_S_FREQUENCY When i try to change the frequency of the tuner. They both return "Invalid Argument". I am coding like this: ioctl(*fd, VIDIOC_G_FREQUENCY, &vFrq) where vFrq is a struct v4l2_frequency and i am using vFrq.input = 0 (i checked that it has a tuner attached) and *fd is my /dev/video0 - opened fine. The error code specifies that the problem is with the request or third argument - does anyone have an idea as to which/why the argument is invalid? Thanks -Brian
