One of the OpenPLi image developers (Milo) said this would be relatively easy to implement. He had the following to say:
"You could bast this option on the amBX grabber code which takes a screenshot about 10 times a second. For the detection you would only have to look at the Luma (Y component) which makes processing a lot easier."

Where to set these options in the menu?In that case, have you tried to use the 'auto' policy (echo auto > /proc/stb/video/policy, and/or echo auto > /proc/stb/video/policy2)
That seems to do just that, auto letterbox / pillarbox zoom.

Activities need to test.the auto option is not yet in the menu, you have to use the commandline for now.
if you think they are useful we can add them
Maybe for Russian users as necessary.

Another wanted to ask.
That this mode 16:10 letterbox, to ET does not exist?
not sure what you mean, a tv is either 4:3 or 16:9. Or do you have a 16:10 screen?
there are two settings: policy and policy2.
One configures how to display nonstandard formats on 4:3, and the other how to display nonstandard formats on 16:9

Russian-speaking users of ET.
They speak a Dream 800 has such a regime.
I can not check myself, there is no Dream .

thank's for hint, just missed them. Hope now everything is covered.
I think we should only add 'auto'.
For instance 'policy' is used automatically, when the tv aspect ratio is 4:3.
/proc/stb/video/policy will be used instead of policy2, when that is the case.
I think adding 'policy' to the list of 'policy2' choices adds confusion.
Also, nonlinear does not make much sense for widescreen formats.
It only makes sense to stretch 4:3 to 16:9 displays, not the other way around.
So I would keep that one out of the policy2 choices as well.
Now regarding the 'auto' choice.
I think we should only show that choice if the hardware supports it (e.g. check policy_choices)
