  1. I've tried to download the video by using N_m3u8DL-RE with a key
    It successfully downloaded the file, but the decrypted video is wrong.
    Here is what I've tried:

    The decryption of the download version didn't work as expected. I cannot watch video content.
    Please help me to find out the correct decoding method

    Thanks you.

  2. can you paste your command you used?

    make sure mp4decrypt or/and shaka-packager in your system variable path.

    key cached:

    Code:
    ec479d83917c42298bb86303e6911949:9eeb0fb0e0782ec620b6dee66c1c58a2
    but it from 2022, not sure if the key will work or not.

    Your command seems correct... but it looks like the key you're using for decryption is incorrect

    Try again to decrypt with key provided by @Shellcmd
    Code:
    N_m3u8DL-RE "https://www.kanopy.com/kapi/manifests/dash/10438103.mpd" --key ec479d83917c42298bb86303e6911949:9eeb0fb0e0782ec620b6dee66c1c58a2 -M format=mp4
    And if it still not work then post video link here

    [Attachment 79280 - Click to enlarge]


    this is the kid, and this is from pssh into mpd. your RE command use another key (also wrong key, real key is kid+key 32+32 characters, your kid:key is totally wrong also for characters numbers)
    so your real key, as other users above say, it's the key provided by shellcmd

  7. Looks like someone's messing either with you, or the keys.

    Code:
    --key n0suchd3v1c3f113:r3adth3fuck1ngma2ua1
    Translates into..

    You got the wrong keys because the Widevine L3 Guesser Extension does not have the challenge scheme for Kanopy using license server https://kcms.kanopy.com/api/v1/playback/widevine_license.


    Suggest that you create a .har file and upload to FoxRefire. He is very fast, efficient and always willing to help.
