Finding keys for an encrypted livestream

[samantas]

Hello,
I'm from Greece and recently one of our free-to-air nation-wide channels implemented DRM on its livestream. If your user agent is Chrome on Windows it tries to play this mpd

By examining the urn:uuid I can tell it supports playready and widevine l3
As for the license challenge, it performs a post request at

https://antenna-plus.live.ott.irdeto.com/licenseServer/widevine/v1/antenna-plus/license?contentId=ant-1&ls_session=

The ls_session does change every time and doesn't stay active for long
I want the keys so I can be able to watch the live stream since their website and app are pretty stupid. On my Linux laptop it's telling me I'm using a second screen and doesn't play and on my android phone it crashes even after hiding root.
There's a small chance it's geoblocked since I tried https://cdrm-project.com/ (getwvkeys clone) and it throws

Error 403: {"code":130302,"message":"Content is not available via the proxies."}

whats the site?

whats the site?

watch.antennaplus.gr/
You need to register a free account since they disabled guest login
Use a windows user agent for the site to load if you are on Linux

the license server is geoblocked, so you have to have a greek ip address for the request or you get that error "content is not available via the proxies".

in that case you would need a proxy thats not blocked to use the website, or use the script on the scripts page cdrmp.py as that would send the license request from your ip(but i dont think its currently working).
Or you can use your own cdm

heres the key for ant-1 anyway

How did you get the key? All the scripts I tried threw weird errors
Did you change the base.url on cdrmp.py?
Assuming you did use cdrmp.py can you share your modified file?

[ElCap]

I used my own cdm and script to get the key.
No headers needed. Just pssh and license url.

Can you try one more?

Also what script did you use? I have dumped my CDM from my brand new android device but I don't know how to progress any further
