i.MX6 Video combiner

i.MX6 Video combiner

[Jean-Michel Hautbois]

Hi all,

I read in the i.MX6 TRM that it can do combining or deinterlacing with VDIC.
Has it been tested by anyone ?
Could it be a driver, which would allow to do some simple compositing
of souces ?

Thanks,
JM

I've added VDIC support (deinterlace with motion compensation) to the
capture driver, it's in the my media tree clone:

git@github.com:slongerbeam/mediatree.git, mx6-media-staging

it is activated if user sets the motion compensation control to
1 (low motion), 2 (medium motion), or 3 (high motion), for
example:

# v4l2-ctl --set-ctrl=motion_compensation=2

Thx for the tip :).
And in fact, it is "only" deinterlacing, not combining two planes with
background as specified in the TRM (or did I miss something ?).

Hi JM, yes it is deinterlace only, the combiner in the VDIC is not
being used.

Well, I don't really know if it would be possible to have it too, and
how difficult it is. Maybe as a m2m device, as it could be driven by
gstreamer for instance and would replace pure software composition
element...
I may need to take some time and look further into this, but if anyone
has tested it, or can give me advices on how it should be done, it can
help (a lot)... :).

Thanks,
JM
