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.
Example
#include<opencv2/opencv.hpp>
#include<iostream>
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.
