How to download MPD video from Kanopy?

[JSwamie]

I have been searching online, but I haven't been able to find a conclusive answer on how to download videos from Kanopy. I am trying to download The Most Dangerous Man in America: Daniel Ellsberg and the Pentagon Papers. The URL is: https://kcms.kanopy.com/api/v1/playback/2e35b53e-f0ca-41c3-b9f8-e193a8f086e7/dash_nohdcp/master.mpd

I have tried a few methods using yt-dlp, but each one gives me an encrypted video. I did --list-formats to find the formats with the --allow-unplayable-formats flag and got this:

I figured out how to find the formats after, but without specifying it automatically downloaded the best combination (GMMvEvXn+o75gzeR4):

Now that I have the mp4 video and m4a audio files, how do I merge them and decrypt them if needed?

easy use N_m3u8DL-RE to download and decrypt it, you must have key to decrypt it
example like this :

N_m3u8DL-RE https://kcms.kanopy.com/api/v1/playback/2e35b53e-f0ca-41c3-b9f8-e193a8f086e7/dash_nohdcp/master.mpd --key [key:key] -M format=mp4

I don't need to download it again because I already downloaded the encrypted mp4 and m4a files right? I already was able to find the key/KID, but when I've tried to decrypt the video file using mp4decrypt, the processed file is not decrypted.

Is the key the default KID? I have tried using the CDRM-Project tool (https://cdrm-project.com) with the correct PSSH and license URL, but I don't think my headers are correct and I couldn't get it to give the key that way.

I will try that tool you mentioned after I'm out of school. Looks like it simplifies the process.

default KID is not the key,
need login, i dont have any public library card or university login

Okay, how do I find the key? I was under the impression CDRM-Project could do this but I haven't been able to get it to work.

Here's the license request with headers:

Hi Hencha, I'm a complete newbie to downloading videos from kanopy. Can you please guide me on how to run this program and find the necessary details on kanopy network tab? I've been trying to find in many places on the internet on how to run this, but I'm running into many issues. I would really really appreciate your help because I've hit a roadbloack. I also sent you a friend request on discord, hoping you might be able to connect with me over there!
