Explanation

Include Libraries:
- #include <opencv2/opencv.hpp>: Includes OpenCV for video processing.
- #include <iostream>: Used for input and output operations.
Open Video File:
- VideoCapture cap("path/to/your/video.mp4");: Opens the video file for reading.
- Checks if the file was opened successfully. If not, prints an error message and exits.
Create Window:
- namedWindow("Video Player", WINDOW_AUTOSIZE);: Creates a window to display the video frames.
Playback Control:
- bool isPaused = false;: Initializes a flag to control playback state.
- Inside the loop:
  - If isPaused is false, capture a new frame from the video.
  - If frame.empty(), it means the video has ended, and the loop is exited.
  - imshow("Video Player", frame); displays the current frame in the window.
  - waitKey(30); waits for 30 milliseconds for a key press. If ‘q’ is pressed, the loop exits. If ‘p’ is pressed, it toggles the isPaused

    state to pause or resume playback.
Cleanup:
- cap.release();: Releases the video file resource.
- destroyAllWindows();: Closes all OpenCV windows.
