Youku's webDRM decrypt help

[Feddryx]

I was about to download this youku's drama
https://www.youku.tv/v/v_show/id_XNjUyODU0NTMyNA==.html

I have also got the key
9dfc93b217de571409049a4c895de039:99db0243b80317209 01fdff0a6768631

But in this video, they are using webDRM instead of the usual cbcs
I tried to decrypt it with mp4decrypt and it didnt work


Could anyone managed to find the way? Thank youu:3

Need access.

Access to the site or video? I'm pretty sure that its giving 6 minutes of free to watch. If it access to the site, maybe try to change dns or use vpn, bcs mine just working fine even in incognito mode

I found it out!! the init data was encrypted, you need to decrypt it first. the youku uses wasm for it, the key is in wds. After i decrypt the init data, then i can use mp4decrypt as well

Hi, I looked carefully at your problem, you will need an account to download the video completely.
