Terrible performance with QMediaPlayer and QVideoWidget

Question

I see a terrible performance while trying to play videos with QtMobility 1.2.0 and Qt 4.7.4 on Ubuntu 10.10 (Pentium 4 2.80GHz

Answer 1

There is nothing wrong with your code, you are just passing the ball to Qt for the decoding and playback of the movie.

You are either using a build of Qt that doesn't have hardware acceleration enabled, or your system doesn't have the proper hardware for Qt to accelerate decoding and playback.
