[packman] [openCV] cvCaptureFromFile returns NULL

[trashing at gmx.net]

Hi packman users,

I've installed the openCV package from packman repository (openSuse 11.0) and 
tried to open an avi-file but unfortunataly it doesn't work. 
cvCaptureFromFile returns for several avi files NULL. I also tried some 
examples from the packages with the uncompressed.avi from openCV test files. 
But it also doesn't work.

Any suggestions, what goes wrong?

Installed packages:
$ rpm -qa | grep opencv
opencv-devel-1.0.0-0.pm.1
opencv-debugsource-1.0.0-0.pm.1
libopencv1-1.0.0-0.pm.1
opencv-1.0.0-0.pm.1
opencv-debuginfo-1.0.0-0.pm.1

greetz,
Manuel
