Struggling to get DRM keys from NPOStart

[RealPhali]

What the title says really; I've followed the various guides on here and I have been able to find the stream.mpd and download the files successfully with yt-dlp, but I am running into a wall getting the keys to decrypt.

I've installed Tampermonkey and the relevant scripts, and as far as I can tell I'm finding the correct pssh and license urls, but I am getting 401 errors from keysdb when trying to get the key. Are there any optional tools I can run locally instead of keysdb, since IPs might be the issue?

(I can't really give you the download command with the mpd since it's tied to your IP)

You can try any of the 4 key extractors: @foxrefire's addon, @cdrm project's forxrefire modified addon, @angela's hell noob pack or @larley's fetcher

If you have the right VPN and you can watch content easily on that site, you can also use a batch downloader for npo.nl start:

python widefrog.py "https://npo.nl/start/video/eurovisie-songfestival-1970"
python widefrog.py "https://npo.nl/start/video/25-jaar-eurovisie-songfestival"

Or if you're old fashioned, you can always write your local custom script ¯\_(ツ)_/¯. It's explained in the sticky threads. Keep in mind, you have to do the downloading with the same IP that you use to obtain the mpd.

Thanks! I tried the FoxRefire guesser addon now, but I'm still getting the 401 error: https://ibb.co/RD9bwhH

Is there something I'm doing wrong that I'm not seeing?

your error is about cdrm guesser (and error for me too)

i've talk about FoxRefire guesser. and this work fine
