How to Count Frames in a Video using OpenCV (cv2.VideoCapture)

To determine the number of frames in a video using 'cv2.VideoCapture' in OpenCV, you can follow these steps:

1. Import the 'cv2' module:

import cv2

2. Create a 'VideoCapture' object by passing the video file path:

video = cv2.VideoCapture('path_to_video_file.mp4')

3. Check if the video file was successfully opened:

if not video.isOpened():
    print("Error opening video file")
    # Handle the error as needed

4. Get the total number of frames in the video:

total_frames = int(video.get(cv2.CAP_PROP_FRAME_COUNT))

5. Release the 'VideoCapture' object and close any open windows:

video.release()
cv2.destroyAllWindows()

6. Print or use the 'total_frames' value as needed:

print("The video has", total_frames, "frames.")

Please make sure to replace 'path_to_video_file.mp4' with the actual path to your video file.
