Comment 14 for bug 1830146

IMO it's a bug in checkbox, kernel doesn't do anything wrong.

The metadata device only has capability V4L2_CAP_META_CAPTURE, it doesn't have V4L2_CAP_VIDEO_CAPTURE, which is required for capturing video.

Please see the example in linux kernel doc and modify checkbox accordingly:
