Opencv-Python中cv2.CV_CAP_PROP_FPS错误

Question

我目前正在使用opencv 3.2.0和Python 3.5.2。在执行以下代码时：

videoCapture = cv2.VideoCapture(file_path)
fps = videoCapture.get(cv2.CV_CAP_PROP_FPS)
size = (int(videoCapture.get(cv2.CV_CAP_PROP_FRAME_WIDTH)),
        int(videoCapture.get(cv2.CV_CAP_PROP_FRAME_HEIGHT)))

我遇到了以下错误：

Traceback (most recent call last):
  File "videoEditor.py", line 29, in <module>
    fps = videoCapture.get(cv2.CV_CAP_PROP_FPS)
AttributeError: module 'cv2.cv2' has no attribute 'CV_CAP_PROP_FPS'

有人能告诉我我应该做什么吗？

Answer 1

在OpenCV 3.2中，删除标志前面的CV。 这样应该能正常工作。

videoCapture = cv2.VideoCapture(file_path)
fps = videoCapture.get(cv2.CAP_PROP_FPS)
size = (int(videoCapture.get(cv2.CAP_PROP_FRAME_WIDTH)),
        int(videoCapture.get(cv2.CAP_PROP_FRAME_HEIGHT)))

Eshirima的答案解决了问题。 但是仅供参考，我想向您展示另一种执行此操作的方法，如文档中所述：https://docs.opencv.org/2.4/modules/highgui/doc/reading_and_writing_images_and_video.html#videocapture-get。

videoCapture = cv2.VideoCapture(file_path)
width  = int(videoCapture.get(3))
height = int(videoCapture.get(4))
fps = int(videoCapture.get(5))
