How to get the duration of video using cv2

Question

I can only get the number of frames CAP_PROP_FRAME_COUNT using CV2.

However, I cannot find the parameter to get the duration of the video using cv2.

Answer 1

Capture the video and output the duration is seconds

vidcapture = cv2.VideoCapture('myvideo.mp4')
fps = vidcapture.get(cv2.CAP_PROP_FPS)
totalNoFrames = vidcapture.get(cv2.CAP_PROP_FRAME_COUNT);
durationInSeconds = float(totalNoFrames) / float(fps)

print("durationInSeconds: ",durationInSeconds,"s")
