VIDIOC_SUBDEV_ENUM_MBUS_CODE — Enumerate media bus formats
|struct v4l2_subdev_mbus_code_enum *
File descriptor returned by
This is an experimental interface and may change in the future.
To enumerate media bus formats available at a given sub-device pad
applications initialize the
index fields of struct v4l2_subdev_mbus_code_enum and
VIDIOC_SUBDEV_ENUM_MBUS_CODE ioctl with a
pointer to this structure. Drivers fill the rest of the structure or return
an EINVAL error code if either the
index are invalid. All media bus formats are
enumerable by beginning at index zero and incrementing by one until
EINVAL is returned.
Available media bus formats may depend on the current 'try' formats
at other pads of the sub-device, as well as on the current active links. See
VIDIOC_SUBDEV_G_FMT for more information about the try formats.
Table A.99. struct v4l2_subdev_mbus_code_enum
|__u32||Pad number as reported by the media controller API.|
|__u32||Number of the format in the enumeration, set by the application.|
|__u32||The media bus format code, as defined in the section called “Media Bus Formats”.|
|__u32||Reserved for future extensions. Applications and drivers must set the array to zero.|
