this is a part of my code
PCL_VideoWriter.open(FileName.toAscii().data(),CV_FOURCC('M','P','4','2'),FPS,cv::Size(640,480));
// MainTimer->start(viewer_thr->loop_time);
if(SLAM_IMG_Capture_flag == 1)
{
FileName.clear();
FileName = "Video/"+CurrDateText+"-"+CurrTimeText+"-SLAM"+".avi";
SLAM_VideoWriter.open(FileName.toAscii().data(),CV_FOURCC('M','P','4','2'),30,SLAM_IMG.size());
}
if(Raw_IMG_Capture_flag == 1)
{
FileName.clear();
FileName = "Video/"+CurrDateText+"-"+CurrTimeText+"-RAW"+".avi";
RAW_VideoWriter.open(FileName.toAscii().data(),CV_FOURCC('M','P','4','2'),30,RAW_IMG.size());
}
I am new to OpenCV, does anyone know how to fix this problem? little clues would be appreciated
