Hi,<div><br></div><div>I am a software developer currently working on a (cross-platform) Video Quality Analyzer application</div><div>for a project at university. It will most likely be released as open source software when it is finished.</div>
<div><br></div><div>I am posting to this list to ask the video encoding/quality experts what is essential</div><div>in comparing video quality according to them.</div><div><br></div><div>A few important design choices I have made:</div>
<div>- libav is used to open video files in order to support many video formats out of the box</div><div>(and to support extraction of information from decoder, for example motion vectors)</div><div>- image processing plug-ins and tools are extensible through scripting and dynamically linked plug-ins</div>
<div><br></div><div>So, most important question:</div><div>What plug-ins would be essential in this kind of application for you?</div><div><br></div><div>Also, if you would be interested in more information or if you would like to try writing</div>
<div>your own script or plug-in for this application, you can contact me by e-mail.</div><div><br></div><div>Kind regards,</div><div>Wesley S.</div><div><br></div><div>PS: here's a little preview screenshot of the current user interface:</div>
