Hello everyone!
I sincerely apologize for the inconvenience. Although I have searched everywhere on Google, I couldn’t find it.
Does anyone have PSSH data that is an actual PlayReady Header for versions v4.0.0.0/v4.1.0.0+ with ALGID set to COCKTAIL?
I really need it to test my program. Thank you so much! 🙏

P/S: I need both the actual PlayReady Header and the KEY.
