python opencv读mp4视频的实例
如下所示:
#获得视频的格式 videoCapture=cv2.VideoCapture('/home/lw/3661.mp4') #获得码率及尺寸 fps=videoCapture.get(cv2.CAP_PROP_FPS) size=(int(videoCapture.get(cv2.CAP_PROP_FRAME_WIDTH)), int(videoCapture.get(cv2.CAP_PROP_FRAME_HEIGHT))) fNUMS=videoCapture.get(cv2.CAP_PROP_FRAME_COUNT) #读帧 success,frame=videoCapture.read() whilesuccess: cv2.imshow('windows',frame)#显示 cv2.waitKey(1000/int(fps))#延迟 success,frame=videoCapture.read()#获取下一帧 videoCapture.release()
