[Longofuzzi]

i,

if you already download encrypted video

decrypt video & audio using mp4decrypt.exe

mp4decrypt --key 539760bb6793dcb77604f6957f52e109:77d1433dfd10afcebb065e1f8ad85f72 encvideo.mpd video.mp4
mp4decrypt --key 539760bb6793dcb77604f6957f52e109:77d1433dfd10afcebb065e1f8ad85f72 encaudio.m4a audio.m4a

join using ffmpeg.exe

ffmpeg -i video.mp4 -i audio.m4a -c copy final.mp4

don't forget use the right key you got

hi man,
just updated the first post, I try to do yesterday but the forum don't allow me.

Just to understand, if I understand correctly I need the keys to decrypt the video/audio.
You passed me two, but to learn, how do I get them too?

thanks!

thank you, works as expected.
It remains to be seen how you found the decryption keys
