Thanks for the help boogieboggie.
1) I tried using firefox with OBS and ""works"". Sometimes in firefox in full screen and OBS records in black, in few occasions it record fine, i don't know if the resolution auto, original or 720 Does that have anything to do with it? Do auto and original have a similar quality?
But, OBS works, ONLY when the firefox windows its not in full screen.
2) Recently i've installed bluestacks and when i reproduce a video in of in Chrome appears "failed to execute 'createmediakeys' on 'mediakeysystemaccess' cannot fetch origin id"
I¿ve tried installing firefox in BlueStacks but can not reproduce de videos and seems bugs in words in OF.
Could you tell me with more details how do you record with OBS?
I forgot to mention that i want to record DRM videos that i bought
Again thanks for the help!
