Here is all the images I've managed to compile.
It appears there is something wrong with the definitions/includes for the Linux platform as any build that defaults to using it will fail to compile and trying to figure out why so many things are breaking is out of my league as I'm sure its just 1 or 2 small things that is causing so many errors.
Hopefully someone that can look into the few compile errors for the Linux platform will come along and provide the fix so we can try getting a RPI4/Rockchip/Allwinner set of images. though im sure they will actually need there own specific platform configs.
For now I would recommend if anyone wants a newer faster openpht player they look into an Amlogic android box such as a S922X/S905X3/S912, S905x3 and s912 can be had for about 50-70$ and S922X for around $80-120(CoreELEC devs say they only officially support Odroid-N2 and GT-KING).
