Video Streaming Application Gaming Project in C++

Explanation

  1. Include Libraries:
    • #include <opencv2/opencv.hpp> includes the OpenCV library for video processing.
    • #include <iostream> is used for input and output operations.
  2. 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.
  3. Create Window:
    • namedWindow("Video Stream", WINDOW_AUTOSIZE); creates a window to display the video frames.
  4. 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.
  5. Cleanup:
    • cap.release(); releases the video file resource.
    • destroyAllWindows(); closes all OpenCV windows.
