但是cv2.CV_CAP_PROP_POS_FRAMES 对我不起作用,那我该怎么办? 尝试输入以下内容: post_frame= cap.get(1)#CAP_PROP_POS_FRAMES = 1 如果您在 Python shell 中键入help('cv2'),您会发现语法有一些修改。 output truncated ... CAP_PROP_PAN=33CAP_PROP_POS_AVI_RATIO=2CAP_PROP_POS_FRAMES=1CAP_PRO...
解决方法 版本升级导致方法名称有所改变! 将 videoCapture.get(cv2.CV_CAP_PROP_FPS) videoCapture.get(cv2.CV_CAP_PROP_FRAME_WIDTH) 改为 videoCapture.get(cv2.CAP_PROP_FPS) videoCapture.get(cv2.CAP_PROP_FRAME_WIDTH) 哈哈,大功告成!
