Description

OpenCV2.2 Windows 7, Qt, 64 bits build with VC2010 PRO.

Frames are saved to a .avi file using 'DIB '. The avi file plays fine using Windows Media Player, but appear left shifted by about 1/4 frame and colors are messed up when played using textbook example code:

cvNamedWindow( "Example2", CV_WINDOW_AUTOSIZE );
CvCapture* capture = cvCreateFileCapture( "c:\\flyball_passes\\Dog3.avi" );
IplImage* frame;
while(1) {
frame = cvQueryFrame( capture );
if( !frame ) break;
cvShowImage( "Example2", frame );
char c = cvWaitKey();
if( c == 27 ) break;
}
cvReleaseCapture( &capture );
cvDestroyWindow( "Example2" );
return 0;

A sample avi file is attached.

Problem confirmed on OpenCV 2.2, Windows 7, No QT, 64 bits build with VC2010 PRO. I've uploaded an example video that can be downloaded from my Dropbox public folder at http://dl.dropbox.com/u/5460464/left.avi.
