So we can say:
Most set top Boxes like Nvidia Shield / Fire TV
Android Phones
Android TVs
all have adb on board, so theres a good chance that minicap also works on them.
That would give us a great way to get the screen from Android based devices and use them on hyperion
Especially for people using 4K Tvs, cause no more expensive grabbers would be needed and no problems with HDR / CEC and so on
Another great thing on minicap is that is can resize the output image to reduce load and bandwith
