OpenCV-Python cv2.CV_CAP_PROP_POS_FRAMES错误 [英] OpenCV-Python cv2.CV_CAP_PROP_POS_FRAMES error

问题描述

目前，我使用opencv 3.1.0，执行以下代码时遇到以下错误：

Currently, I am use opencv 3.1.0, and I encountered the following error when executing the following code:

post_frame = cap.get(cv2.CV_CAP_PROP_POS_FRAMES)

我收到以下错误消息：

文件videoOperation.py，第37行，
pos_frame = cap.get（cv2.CV_CAP_PROP_POS_FRAMES）
AttributeError：'module'对象没有属性'CV_CAP_PROP_POS_FRAMES '

File "videoOperation.py", line 37, in pos_frame = cap.get(cv2.CV_CAP_PROP_POS_FRAMES) AttributeError: 'module' object has no attribute 'CV_CAP_PROP_POS_FRAMES'

使用OpenCV 2.X时，代码应采用以下格式编写：

The code should be write in the following format when using OpenCV 2.X:

post_frame = cap.get(cv2.cv.CV_CAP_PROP_POS_FRAMES)

请参阅< a href =https://stackoverflow.com/questions/30013009/opencv-3-0-0-dev-python-bindings-not-working-properly> opencv 3.0.0-dev python绑定无法正常工作，我知道

在opencv3.0中删除了cv2.cv子模块，还修改了一些常量

the cv2.cv submodule got removed in opencv3.0, also some constants were changed

但cv2.CV_CAP_PROP_POS_FRAMES对我不起作用，那么我想做什么？

But the cv2.CV_CAP_PROP_POS_FRAMES didn't work for me, So what and i suppose to do?

推荐答案

尝试输入此而不是你的：

Try typing this instead of yours:

post_frame = cap.get(1) #CAP_PROP_POS_FRAMES = 1

如果你在Python shell中输入 help（'cv2'），你将会找到一些语法修改。这些都不是数据。只是一个例子。

If you type help('cv2') in the Python shell you will find some modifications to the syntax.These are not all the Data. Just an illustration.

CAP_PROP_PAN = 33
CAP_PROP_POS_AVI_RATIO = 2
CAP_PROP_POS_FRAMES = 1
CAP_PROP_POS_MSEC = 0
CAP_PROP_PVAPI_BINNINGX = 304
CAP_PROP_PVAPI_BINNINGY = 305
CAP_PROP_PVAPI_DECIMATIONHORIZONTAL = 302
