Hello,
is it possible to implement some functionality in the grabber to use(analyse) a perspective part of the source picture?
See the attached picture to see some details about the idea.
Why do I want to have such feature?
-> Because there are more and more 4k/UHD sources and currently only very expensive solutions (HDfury or maybe Ambivision 4k) to capture/get the source picture into the pi.
Therefore I want to use a mini cam in front of the TV (e.g.
The cam has cinch video to go into the already existing usb grabber (instead of the video out from my sat receiver before).
For first tests I received the cam, but maybe it is not ideal because if there is black picture the cam doesn't show black - maybe because of night-sight support of the cam.
-> have to look for a better one...??
But first the requirements in software/hyperion:
If I place the cam in front of the tv the picture will be somehow like in the attached picture (trapez).
I want to crop the necessary part of the picture and expand the smallest size to the longest size (see attached picture).
Therefore I need the functionality in hyperion/grabber
The advantage would be, that I can visualize all content on the TV (Apps on the SmartTV like Netflix, Prime, Youtube; Sky+ Pro Rec., PS3/4, ...)
Should this be possible or are there better ideas?
(for info: german disussion was also started before: https://hyperion-project.org/t…le-%C3%BCber-grabber.837/)
Thanks
