why video is not playing only one frame showing

//PlayVideoFilecpp.sIn //main.cpp

include<opencv2\imgproc\imgproc.hpp>

include<iostream>

include<conio.h> //it may be necessary to change or remove this line if not using windos

////////////////// int main(void) { cv::VideoCapture capVideo; cv::Mat imgFrame; capVideo.open("768x576.avi"); if (!capVideo.isOpened()) { std::cout << "\nerror reading video file" << std::endl << std::endl; _getch(); return(0); } if (capVideo.get(CV_CAP_PROP_FRAME_COUNT) < 1) { std::cout << "\nerror:video file must have at least one frame"; _getch(); return(0);

}
capVideo.read(imgFrame);
char chCheckForEscKey = 0;
while (capVideo.isOpened() && chCheckForEscKey != 27) {
    cv::imshow("imgFrame", imgFrame);
    if ((capVideo.get(CV_CAP_PROP_POS_FRAMES) + 1) < capVideo.get(CV_CAP_PROP_FRAME_COUNT)) {
        capVideo.read(imgFrame);
    }
    else
    {
        std::cout << "end of video\n";
        break;
    }
    //chCheckForEscKey = cv::waitkey(1);
}

if (chCheckForEscKey != 27) {
    cv::waitKey(0);




}
return(0);

}

code is working okay but it only show frame why not playing whole video ?
