Could you use libmediactl and libv4l2subdev instead here as well? They do
actually implement much of what you do here. Feel free to comment on the
API. The libraries have a little bit different background than this one.
Obviously there's functionality in this library what's not in the two; some
of this might belong to either of the two libraries.
I think we'll need V4L2 sub-device related information stored next to the
media entities as well, so that's something to be added.
