viedeo codecs

The QNX RTOS 6.2 Momentics is unable to play viedo filesas .avi, .mov,
…mpg.
Well, strange, they are basic multimedia tool in all o.s., don’t know
why they could not be used in QNX…
I have found the mpegsystem.so inside the dll forder in QNX, but as I
attempt to open an mpeg video file it gives that answer (“can’t load
mpegsystem.so plugin”), as well as attempting to play avi or mov files
(“can’t load plugin avi.so, qt.so…”).
Mistery.
Anyone knows how to install video codecs?
