利用python-opencv读取视频，计算视频总帧数以及FPS

1、计算总帧数
import os import cv2 video_cap = cv2.VideoCapture('ffmpeg_test.avi')
frame_count = 0 all_frames = [] while(True): ret, frame = video_cap.read() if
ret is False: break all_frames.append(frame) frame_count = frame_count + 1 #
The value below are both the number of frames print frame_count print
len(all_frames)
2、计算视频中的FPS，即每秒传输帧数（Frames per second）
import cv2 if __name__ == '__main__' : video = cv2.VideoCapture("video.mp4");
# Find OpenCV version (major_ver, minor_ver, subminor_ver) =
(cv2.__version__).split('.') if int(major_ver) < 3 : fps =
video.get(cv2.cv.CV_CAP_PROP_FPS) print "Frames per second using
video.get(cv2.cv.CV_CAP_PROP_FPS): {0}".format(fps) else : fps =
video.get(cv2.CAP_PROP_FPS) print "Frames per second using
video.get(cv2.CAP_PROP_FPS) : {0}".format(fps) video.release();
