Ripping cartoons from Boomerang

[videofindersTV]

Hi! I'm new here.

Anyways, I was wondering if any of you guys could help out with something I'm doing.

I'm trying to rip cartoons from Boomerang, but they use encryption. They have both Marlin and Widevine options. Whenever I try to do the Marlin option, it gives me an output with garbage data. Same thing with Widevine.

Boomerang has videos stored in DASH. The manifest.mpd file is encrypted. I have no idea how to decrypt it. I've tried mp4decrypt, and it gave me garbage.

Are there any other ways to do this?
