Hi guys,

if you're into video conversion (between codec to codec or with same codec but different settings, etc etc), a couple of objective measures are needed to provide indeed objective feedback on the quality of encoding.
As seen as on Linux I could not find any tool to do so, I coded one myself.
The webpage is here:

There you'll find a simple description, usage, the software and sources.
If you have any question, please do ask!

Cheers!
