Review of the test I did:
I tested it with this seller, recorded a video of the entire process.
I could not get it to work on my PC. As a result I won't buy it.
We used a less known DRM test site located here for the test:
Test DRM protected stream using videojs player with Nuevo. Enable DRM playback utilizing the HTML5 Encrypted Media Extensions (EME).
www.nuevodevel.com
However, he then offered me to connect to his computer by Anydesk, where I saw it pulling keys from amazon and the site listed above.
When he connected to
https://www.nuevodevel.com/nuevo/showcase/drm using his plugin, it failed to detect the MPD link and generated one key pair. Then after he tested again it started pulling links.
This could actually be legit, but it could also be a very well coded fake plugin that generates fake data. Will have to test with a MPD panel to be 100% sure.
For now I can't be sure but will retract my warning about it. If anyone buys and wants to test the MPDs let me know.
