I am using Python 3.5 and Opencv for an interactive video. However I can't figure out how to detect when my video finishes playing. Any ideas how I can detect when the video ends?

推荐答案

当ret为False时，表示视频位于最后一帧.

When ret is False, it means that the video is in the last frame.

这是我的代码.您可以尝试一下.

Here is my code.You can try it.

import cv2

video_capture = cv2.VideoCapture("huge.mp4")
while True:
    ret, frame = video_capture.read()
    if ret:
        cv2.imshow('Video', frame)
        if cv2.waitKey(1) & 0xFF == ord('q'):
            break
    else:
        break
video_capture.release()
cv2.destroyAllWindows()
