How to find key of an offline encrypted video

[nic030]

Hi,
I downloaded an encrypted video a few days ago. The video is unfortunately no longer available online so I wonder if it is possible to find its key anyway.
Thanking you

you might get lucky if you can still request the key from the license server (using the PSSH)
Do you have the license URL and the PSSH somewhere?

no key found with this pssh
lic url is generic url
need auth token to get key. but if your video isn't available now, no chance to get the key and decrypt
