Is the source code on github up to date that I could build a raspberry pi image? And if not can I get the up to date source code for this project please and thank you?
The source codes are available on Popcorn-official organization repos:
The up to date branches are the “development” branches.
But, the Raspberry pi have ARM arch, so you either install Android on it and try to run the android app, or you use Gnu/Linux and try to build the desktop version for ARM… which isn’t just trivial and require changes and compromises (but it was already done by someone in the past).
If you really want to go this way, you will need to use the community version of nwjs for ARM to start with and eventually use omxplayer as video player.
