使用python-opencv读取视频,计算视频总帧数及FPS的实现
作者:强少~、
今天小编就为大家分享一篇使用python-opencv读取视频,计算视频总帧数及FPS的实现方式,具有很好的参考价值,希望对大家有所帮助。一起跟随小编过来看看吧
如下所示:
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();
以上这篇使用python-opencv读取视频,计算视频总帧数及FPS的实现就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持脚本之家。
