How can i decrypt a stream from Joyn?

[PyNoob]

Hi, it is my first time to try downloading an encrypted stream.

This is a free Joyn video: https://www.joyn.de/play/serien/willkommen-bei-den-echten-louds/1-6-the-banana-split-decision
I have the manifest url:

and the lic url:

Thank you for the Keys.

I want to learn it myself to get the keys for future encrypted stream downloads.
I have read tutorials for this, but most they are to old and not up to date. And other tutorials do not explain how actually get the keys for decryption.
Can someone please explain this to me?

i have l3.py, N_m3u8DL-CLI, yt-dlp and the bento4-sdk files. but i don't know how to get the Keys.

Go to cdrm-project.com
Put in license url
Copy pssh from mpd and paste into the pssh field
Press send

Thank you, it works very well.

The video is now decrypted.
I have a video.mp4 file and a audio.aac file , how can i get this together? can i use one of the Bento4-SDK tools for this?

[cedric8528]

ffmpeg -i video.mp4 -i audio.aac -c copy new.mp4

now everything works very well. Thanks to all for the help.
