Hello everybody.
I just installed the Computer Vision Toolbox with MATLAB R2012a and I'm trying to get a face tracker working. Unfortunately I'm stuck at reading a video file from my computer.
When I try to run
reader = vision.VideoFileReader('movie2.avi');
I get a long list of errors:
Error using dspmmfileinfo>getFileInfo (line 82) Unable to process file (C:\Radu\Facultate\Matlab R2012a 32 bit\toolbox\vision\visiondemos\vipmen.avi): Unspecified error
Error in dspmmfileinfo (line 40) cache.fileInfo(index) = {getFileInfo(filename)};

Error in C:\Radu\Facultate\Matlab R2012a 32 bit\toolbox\vision\vision\+vision\VideoFileReader.p>VideoFileReader.VideoFileReader (line 131)
I know that vipmen.avi is the default video file but I don't use that file and in any case, it's where it should be. movie2.avi is in the Path and even if I give the fullpath it shows the same errors. I'm running on Windows 7 as administrator.
Any ideas?
Thanks, Radu

Hi Radu,
I had the same problem on a mac, but I changed the file to mpeg using Any Video Converter (you can find it for free online). Once I got the files in mpeg mode, it read them ok and I stopped getting all those error messages.
Hope this helps!
