drm in francetv

If I can't use N_m3u8DL-ER and have to download the video and audio as two files, how do I go around decrypting them?

mp4decrypt --key KID:KEY encrypted_video.mp4 decrypted_video.mp4
https://www.bento4.com/documentation/mp4decrypt/
or
shaka-packager
https://shaka-project.github.io/shaka-packager/html/documentation.html#encryption-decryption-options

Can you give a example with a audio file with mp4decrypt? I can't seem to get it to work with audio files, but it did for the video. Does it matter if its a .m4a?
I use the same keys for both the video and audio?

can be the same or different
in this case, the key is the same. But sometimes you need to use shaka-packager instead of mp4decrypt, so it is more convenient to use N_m3u8DL-RE
