Yes, so that non multi-plane aware apps keep working.
There is the multi-planar API and there are multi-pla

Hi,
I've got one limitation for v4l2-mem2mem devices: a v4l2-mem2mem
device driver which can't support *both* V4L2_BUF_TYPE_VIDEO_CAPTURE
and V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE capture buffers.
AFAIK/U, this limitation is unjustified.
So, with v4l2-mem2mem :

Easy:
1) Split off the control part from videodev2.h. Controls are almost 30% of
videodev2.h. I think maintaining controls would be easier if they are moved
to e.g. linux/v4l2-controls.h which is included by videodev2.h.
Ack.
2) Currently there are three types of controls: st
