Need help to find Key for an encrypted MPD video

[jackpolkichcha]

Hi guys,
First of all, I’m new to this forum.

I tried to find a solution from this forum but I couldn’t find the answer that I’m looking for.

I’m trying to download & decrypt an encrypted dash video (Widevine cenc) from a website.

I did managed to download the video and audio streams using yt-dlp. However now I want to decrypt those files. For my understanding, I think that I’m gonna need the key for that. I got the pssh & KID from the mpd file. But I dont know that how can I obtain the key bacause the Widevine decrypter isn’t working right now.

So I want to know that, how to get the key for decrypt the above mentioned files.

Thanks in advance.
