Description
Summary of the bug:
I generated some junk from /dev/urandom and fed it to cavs, and it just silently ignores the junk and outputed no frame. It should at least split out some error messages.
How to reproduce:

Replying to cehoyos
Oh OK, seems like you can reproduce this bug. Then I won't upload the file then.

I'll upload "ran" file some time later as I don't have access to my PC right now.
