Note that I might not merge this element, as I'm currently writing
v42transform, with the goal to support color
transform/scaling/colorbalance/cropping and be able to instantiate more then 1
element. Though your help in testing it will be appreciated as I don't own that
many HW with such v4l2 drivers.

I mean custom, in the sense not using the usual macro. Though I haven't check
the definition of LOG_CAPS.

Something that works for other platform then yours, and that scan the HW once,
along with scanning the decoders.
