How to count the total number of frames in OpenCV using C++?

OpenCVC++Server Side ProgrammingProgramming

We will learn how to calculate the total number of frames in OpenCV. Using OpenCV, it is elementary to count and show the total number of frames of a video. However, you have to store one thing in mind that we cannot count the total number of real-time video frames. Because a real-time video does not have a specific number of frames.

The following program counts the number of total frames and shows it in the console window.


using namespace std;
using namespace cv;
int main() {
   int frame_Number;//Declaring an integervariable to store the number of total frames//
   VideoCapture cap("video.mp4");//Declaring an object to capture stream of frames from default camera//
   frame_Number = cap.get(CAP_PROP_FRAME_COUNT);//Getting the total number of frames//
   cout << "Total Number of frames are:" << frame_Number << endl;//Showing the number in console window//
   system("pause");//Pausing the system to see the result//
   cap.release();//Releasing the buffer memory//
   return 0;

As the output, we will get an integer value.
