  1. Hi

    I'm new in the DRM business.
    I use N_m3u8DL-RE to download from blockbuster.dk
    It shows a key and a id, so I think, it will be decrypted correctly, wow!
    But doesn't. The mp4 file is not decrypt.
    So I try to decrypt manually but failed too with:

    mp4decrypt --key xxxxx video.mp4 video_decrypted_2.mp4

    So is N_m3u8DL-RE not getting the right key?

    I didn't see processes related to decryption according to your log, so I would assume that you didn't provide the keys.

    In fact, you should provide the keys and pass them to N_m3u8DL-RE, not waiting for it to automatically decrypt it. It's not magic.

    Since you listed logs, I'll do it too:

    I've got the keys first:

    And then I pass the keys to N_m3u8DL-RE so it could invoke mp4decrypt to decrypt it for me, and the larger the video file is, the longer the decryption process takes. And you will see some texts saying Decrypting using MP4DECRYPT...

    Code:
