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.
How to do that?
Thank you very much.

Two ways to get a youtube video duration Corresponds to 6 minutes and 22 seconds. If needed, you can parse the ISO duration using duration = isodate. parse_duration(duration) and then video_dur = duration. total_seconds() with the isodate package.
To read a video with OpenCV, we can use the cv2. VideoCapture(filename, apiPreference) class. In the case where you want to read a video from a file, the first argument is the path to the video file (eg: my_videos/test_video. mp4).
In OpenCV 3, the solution is:
import cv2 cap = cv2.VideoCapture("./video.mp4") fps = cap.get(cv2.CAP_PROP_FPS) # OpenCV2 version 2 used "CV_CAP_PROP_FPS" frame_count = int(cap.get(cv2.CAP_PROP_FRAME_COUNT)) duration = frame_count/fps print('fps = ' + str(fps)) print('number of frames = ' + str(frame_count)) print('duration (S) = ' + str(duration)) minutes = int(duration/60) seconds = duration%60 print('duration (M:S) = ' + str(minutes) + ':' + str(seconds)) cap.release() If you love us?
