[Q] Playstation app and remote play, no drm keys topic

Ok so as im sure everybody knows, the playstation app and remote play don't work without drm keys.

I installed CM12 yesterday, purely on the grounds that someone said they had remote play working on z3 with no drm keys on CM12, i wasn't holding out much hope but it actually worked, i lost my drm keys way back in april, and currently on CM12 my playstation app works pefectly and remote play kind of works (audio's iffy and keeps disconnecting). While this is great, im not too keen on the CM12 rom overall.

Now im wondering if it's possible to grab the related files from CM12 and install them on a stock rom???

Im not a dev or anything so i dont know if it's possible or even what files we'd need, however while manually installing the remote play port i noticed in system/framework there is a com.google.widevine.software.drm.jar and it also has an xml in (i think) etc/permissions. Seeing how widevine is something to do with drm keys and i've nevere noticed anything named widevine in any folders on my z2 prior to flashing CM12 im wondering if this is what's making remote play and playstation app work, and if/how i can get it onto a stock rom?

Any idea's??? Also im assuming there would be more files needed that just the .jar and .xml, but i have no idea what
