Unable to read video in opencv - c++

Question

I am trying to read video file, but its throwing error.
The code is:
#include <iostream>
#include <opencv/highgui.h>
#include <opencv/cv.h>
#include <opencv2/opencv.hpp>
using namespace cv;
int main(int argc, char* argv[])
{
Mat inputVideo;
Mat frame;
Mat HSV;
Mat tracking;
char checkKey;
VideoCapture capture;
capture.open("video/input.mp4");
capture.set(CV_CAP_PROP_FRAME_WIDTH, 640);
capture.set(CV_CAP_PROP_FRAME_HEIGHT,480);
namedWindow("Original Video", WINDOW_AUTOSIZE );
while(1){
capture.read(inputVideo);
if (!inputVideo.empty())
{
imshow("Original Video",inputVideo);
}
waitKey(20);
}
return 0;
}
On running this code, the error I am getting is:
Unable to stop the stream: Inappropriate ioctl for device
(video_reading:3459): GLib-GObject-CRITICAL **: g_object_set:
assertion 'G_IS_OBJECT (object)' failed
I tried looking for solutions, but i did not get it. Can some one help me in solving this error.

I made little changes in your code. Try this:
#include <iostream>
#include <opencv/highgui.h>
#include <opencv/cv.h>
#include <opencv2/opencv.hpp>
using namespace cv;
int main(int argc, char* argv[])
{
Mat inputVideo;
Mat frame;
Mat HSV;
Mat tracking;
char checkKey;
VideoCapture capture;
capture.open("video/input.mp4");
capture.set(CV_CAP_PROP_FRAME_WIDTH, 640);
capture.set(CV_CAP_PROP_FRAME_HEIGHT, 480);
namedWindow("Original Video", WINDOW_AUTOSIZE);
while (1) {
capture >> inputVideo;
if (inputVideo.empty())
break;
imshow("Original Video", inputVideo);
waitKey(1);
}
capture.release();
return 0;
}
