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. https://www.amazon.de/gp/produ…age_o00_s00?ie=UTF8&psc=1)
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
