So, if you don't want to download LibreEngineering again, just open 'formwidget.py' in LibreEngineering folder and comment out this line:
#from applications.player.mainwindow import Player

app.setStyle("plastique")
that is change it to:
#app.setStyle("plastique")
It's my personal preference, I like the Plastique style more, plus it give the application a consistent look on both Linux and Windows.

Stream #0.0: Video: mpeg4, yuv420p, 384x288 [PAR 1:1 DAR 4:3], q=2-31, 400 kb/s
and
frame= 2648 fps=291 q=9.0 Lsize= 6130kB time=105.95 bitrate= 473.9kbits/s
Maybe the 1st one is what it's set to and the 2nd one is a source's actual bitrate?
I've got no idea what they mean and why they're different. Need multimedia guru help here.

I suggest open a console, type that and see what ffmpeg shows you. If it shows the same info, it must be something to do with passing conflicting arguments to it, that is maybe you can't use Xvid, .mkv and 400 kb/s rate, I don't know. If it does show the bit rate of 400k than it must be Giraffe's bug.

I'm porting my Cute Giraffe app from Mono/C#/Qt(Qyoto) to Python/Qt. I've never used Python before but so far it looks promising and easy. Hope it won't take long to port it all and then continue with Python.
My first impressions of Pythons are very positive. It seems they took the best of Java and C#. Stay tuned... - Mar 11 2010
