Advice for a noob? CDM bitmovin

[Iridule]

A little background. Before a few months ago I'd never used Linux. I started on a learning project and successfully compiled a custom kernel with modules to help me decrypt ps3 hard drive and have read/write access on ufs2 filesystem. That project is successful and finished. Now I am working on learning to use my android 11 Motorola Edge as CDM. I managed to successfully get the bitmovin video keys, download, decrypt and merge files. However my phone says CDM is l1 but key files "bin & pem" went to dumper folder l3? If this worked with bitmovin.... Does this mean theoretically I have my phone as a CDM? I've not been successful with any other site. The few I tried gave me over 10 keys and none of them worked. Thinking I haven't figured out how to find the correct header, PSSH, and license files.

I'm still learning any advice/comments would be appreciated. Thank you.
still confused as why files are going to l3 folder for dumper when I have l1 CDM on phone?

I have searched everywhere in the console and media section of the developer tools for the proper PSSH which I found and the lic URL which I am 90% sure is right...the headers for this site im trying i am not so sure about but i get this error when trying to generate keys. so far the only sites I can get to work are bitmovin and the g4.ie site.

"PSSH: AAAA blahblah==
License URL: [url]*************"*"****
unable to parse license - check protobufs" ...I assume this means I have the wrong headers? I've been trying to search the forums for specifics but no luck. I did manage to download the source material but it is encrypted still.
