If we had DRM support would it only work on x86/x64 kodi?

could you compile your own version for an arm board and have DRM work without a necessary binary blob.

Sadly, it's not possible to do this without a binary blob. Also, we're pretty sure Kodi can't distribute this blob while remaining GPL compliant, so we can't give it to you (though that's still under discussion). So it's only available on platforms that have the blob compiled that users can install themselves. Fortunately, that's pretty much every platform. It's pre-installed in Android, you can get it by simply installing Chrome on x86 platforms, and it is at least compiled on the other ARM platforms, though I'm not sure what the best way is to actually get it onto those platforms.
