Decryption fails using method-2 script

Hi,

I tested the script with a primevideo vid and the full process is OK without any error.

But the MKV file is unreadable using VLC, and mediainfo displays format and codec identifier as V_QUICKTIME.
I checked encrypted file and format is AVC. Decrypted video file is AVC but unreadable too, guess that decryption failed.

Why has this format change with mkvmerge ? I cannot find any setting to modify in the script that would affect this behavior.

quicktime
Any idea ?
Thanks,

Same here with Prime video sometimes

Always happen for me.
I just found out what occurs : decryption fails because it uses a bad key.
I was able to succesfully decrypt a file manually using mp4decrypt.
Key.txt has 3 keys inside, if I don't use the good one, video is unreadble too.

Seems like the script does not use the good key between the 3 provided by key.txt.

OK, I was using "method-2" script, I just tested with main method, with json file and its fine.
