13 VIDIOC_ENUM_FRAMESIZES - Enumerate frame sizes
30 that contains an index and pixel format and receives a frame width
36 This ioctl allows applications to enumerate all frame sizes (i. e. width
37 and height in pixels) that the device supports for the given pixel

47 - **Discrete:** The function returns success if the given index value
48 (zero-based) is valid. The application should increase the index by
54 - **Step-wise:** The function returns success if the given index value
60 - **Continuous:** This is a special case of the step-wise type above.
