13 VIDIOC_ENUM_FRAMEINTERVALS - Enumerate frame intervals
30     that contains a pixel format and size and receives a frame interval.
36 device supports for the given pixel format and frame size.
46 -  **Discrete:** The function returns success if the given index value
47    (zero-based) is valid. The application should increase the index by
53 -  **Step-wise:** The function returns success if the given index value
59 -  **Continuous:** This is a special case of the step-wise type above.
