Can't decrypt mp4(DRM)

[shadowolder]

Hi guys! I found cool software bento4_com/ (mp4decrypt), which can decrypt mp4 drm protected files, but i'm getting error...

When i'm typing

mp4decrypt.exe ddp-192.mp4 ddp-192_final.mp4 --key 58b58c58-400b-11e7-a009-842b2b5247fa

I'm getting

ERROR: invalid argument for --key option

You can't open it, it doesn't have a frontend as it's a commandline app to be used within the dos command line aka cmd.exe
