Stumped with Kiswe Livestream VOD

[BradenCassim]

Hi! I'm trying to download the VOD of a livestream before it is removed on the 31st - bit of a data hoarder/archivist.
I've spent a lot of time figuring out the various guides and here's what I've managed so far:

I guess I'm not sure how to put this all together to get the final video and audio download that I can combine. I'm very savvy with FFmpeg and YT-DLP so that final part isn't an issue, I'm just new to the world of widevine!

Please if anyone can help, I'd be very grateful
Many thanks for your time!

That worked, thank you for your quick response! Decrypted and muxed perfectly.
May I ask if there's a specific guide I can follow to get from what I had to obtaining this key, for future issues? Or do I just need to have a more thorough re-read of the sticky threads and the answer's in there?

You may use either the sticky threads from this forum or a better organized cdm-project how-to's

For the latter, it's pretty much following the generic service guide with a few notes

• the license curl headers include `x-dt-auth-token` and `x-dt-custom-data`
• one needs to grab the correct values from the server responses

# TDP-Keys/Sites/Generic.py

-service_cert = service_cert.content
+service_cert = json.loads(service_cert.content)['license']

-license = license.content
+license = json.loads(license.content)['license']

Thank you for the link and guidance! Next time I need to do something like this, I'll know where to start.
