Explanation

Include Libraries:
- #include <opencv2/opencv.hpp> includes the OpenCV library for video processing.
- #include <iostream> is 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 Stream", WINDOW_AUTOSIZE); creates a window to display the video frames.
Video Streaming Loop:
- cap >> frame; captures the next frame from the video.
- Checks if the frame is empty (end of video). If so, exits the loop.
- imshow("Video Stream", frame); displays the current frame in the created window.
- waitKey(30); waits for 30 milliseconds for a key press. If the ‘q’ key is pressed, exits the loop.
Cleanup:
- cap.release(); releases the video file resource.
- destroyAllWindows(); closes all OpenCV windows.
