13 VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL - Enumerate frame intervals
35 given sub-device pad. Frame intervals only makes sense for sub-devices
40 on the sub-device output pad depend on the frame format and size on the
41 same pad. Applications must thus specify the desired format and size
45 ``pad``, ``which``, ``code``, ``width`` and ``height`` fields of struct
47 and call the :ref:`VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL` ioctl with a pointer
54 other pads of the sub-device, as well as on the current active links.
55 See :ref:`VIDIOC_SUBDEV_G_FMT` for more
58 Sub-devices that support the frame interval enumeration ioctl should
59 implemented it on a single pad only. Its behaviour when supported on
60 multiple pads of the same sub-device is not defined.
