    Thumbs down PSNR and SSIM on Linux

    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:
    http://qpsnr.youlink.org/
    There you'll find a simple description, usage, the software and sources.
    If you have any question, please do ask!

    Cheers!

    Hi all, a quick one.
    I've updated the website even with proper libav* libraries that support Theora streams.

    Cheers,

    Thanks ! I been looking for tool that does objective quality checks like SNR/SSIM/MDI/VQM for video's. Gonna give your tool a shot.

    Let me know if you know of any Subjective video quality tools ( ie PEVQ,VQM ) are tough to find on linux , most of them are not free or opensource.

    Ok, this might sound stupid, but how can I plot the result into graphical representation ?

    Nice work by the way...
