- <para>To query the current video input applications call the
-<constant>VIDIOC_G_INPUT</constant> ioctl with a pointer to an integer
-where the driver stores the number of the input, as in the
-&v4l2-input; <structfield>index</structfield> field. This ioctl will
-fail only when there are no video inputs, returning
-<errorcode>EINVAL</errorcode>.</para>
-
- <para>To select a video input applications store the number of the
-desired input in an integer and call the
-<constant>VIDIOC_S_INPUT</constant> ioctl with a pointer to this
-integer. Side effects are possible. For example inputs may support
-different video standards, so the driver may implicitly switch the
-current standard. It is good practice to select an input before
-querying or negotiating any other parameters.</para>
