Could not parse license message

[captaindooley]

I fully admit, I'm out of my depth here, but I have my CDM and wvd file, I know where to find PSSH and the licensing URL, and I was successfully able to pull keys from bitmovin and tg4.ie as tests... but when I went to pull from a live site I wanted the video from I got a "Could not parse license_message as a SignedMessage, Error parsing message" response.

I also noticed that the PSSH value was MUCH longer than both of my test sites...

What am I doing wrong?

Common wv won't work on crunchyroll. Crunchyroll uses DRMtoday. Wks-keys had code for DRMtoday. Try finding it.
