How to play avi files with psychtoolbox on PC ?

1
Hi

I'am trying to play an avi file with psychtoolbox and I always have
the same message :

Error in function OpenMovie: Incorrect argument type supplied
??? Usage:

[ moviePtr [duration] [fps] [width] [height]
[count]]=Screen('OpenMovie', windowPtr, moviefile [, async=0]);

Here is my code :

moviename=aviread('.\stimuli\grenoble.avi');
[movie movieduration fps imgw imgh] = Screen('OpenMovie', window,
moviename);

What is wrong ?

thanks for your help

This way's correct:

moviename= '.\stimuli\grenoble.avi';
...

"help QuicktimeDemos" for some demos.

i tried to download quick time since it seemed psychtoolbox works with
QT's API an dthe only thing i'have obtained is to hear only one second
of a .mov file (not .avi) without image...
