Okaaay, now I got it. If I wanted to use L1 cdms I would have to extract them oftenly right? And propably They would have to be from physical device and not virtual android studio?
Anyway, it seems more complicated. But what about L2? just of curiosity - where is it used? Never heard of L2.
To decrypt 1080p content I would need L1 keys? L3 would not work? Technically, could I extract L1 cmds from browser and use those?
