19 VIDIOC_SUBDEV_ENUM_FRAME_SIZE - Enumerate media bus frame sizes
33     File descriptor returned by :ref:`open() <func-open>`.
42 This ioctl allows applications to enumerate all frame sizes supported by
43 a sub-device on the given pad for the given media bus format. Supported
48 To enumerate frame sizes applications initialize the ``pad``, ``which``
52 structure. Drivers fill the minimum and maximum frame sizes or return an
55 Sub-devices that only support discrete frame sizes (such as most
56 sensors) will return one or more frame sizes with identical minimum and
60 supported. For instance, a scaler that uses a fixed-point scaling ratio
61 might not be able to produce every frame size between the minimum and
64 sub-device for an exact supported frame size.
66 Available frame sizes may depend on the current 'try' formats at other
67 pads of the sub-device, as well as on the current active links and the
