Hi, I was playing around with Qt4 the last couple of days. After reading the basic tutorial, I wanted to try to write a small GUI as a first exercise. Since I frequently use ffmpeg to convert videos for my iPhone, I decided to write a small frontend for that awesome converter. I never made a GUI before since I thought this would be something really complex - so I had no experience at all - however surprisingly after less than eight hours work I ended up with something which was actually usable.

Maybe someone finds it useful. 32bit: http://www.[PIRACY.mup].com/J19PWDPA6R 64bit: http://www.[PIRACY.mup].com/57QQEDJTWO You will need the Qt4 runtime-library packages libqt4-x11 (~21MB) and libqt4 (~6MB) and maybe some additional dependencies and the ffmpeg binary in a path. This program is freeware and you can distribute it freely as you like as long as you do not charge anything for it.
