无法获取VideoCapture属性，因为未定义属性标识符 [英] Can't get VideoCapture property as the property identifier are not defined

问题描述

我正在尝试处理视频文件中的帧，并知道视频中当前帧的位置.

cap = cv2.VideoCapture('Videos/IMG_2483.MOV')
print("Position : %d" % cap.get(cv2.CV_CAP_PROP_POS_MSEC))

我一直收到此错误:

AttributeError: 'module' object has no attribute 'CV_CAP_PROP_POS_MSEC'

我猜我错误地将属性称为"CV_CAP_PROP_POS_MSEC".我到处都在看，但是我想不通.

提前谢谢！

解决方案

在您安装的Opencv版本中似乎已弃用CV_CAP_PROP_POS_MSEC，请将其更改为cv2.CAP_PROP_POS_MSEC.在Opencv 3.1上对我有用

I am trying to process frames in a video file, and to know what is the current frame position in the video.

cap = cv2.VideoCapture('Videos/IMG_2483.MOV')
print("Position : %d" % cap.get(cv2.CV_CAP_PROP_POS_MSEC))

I keep getting this error :

AttributeError: 'module' object has no attribute 'CV_CAP_PROP_POS_MSEC'

I guess I am wrongly calling the attribute "CV_CAP_PROP_POS_MSEC". I've been looking everywhere but I can't figure it out.

Thanks in advance!

解决方案

It seems that CV_CAP_PROP_POS_MSEC is deprecated in your installed version of Opencv, Change it to cv2.CAP_PROP_POS_MSEC. Works good for me on Opencv 3.1
