要使用cv2.CAP_PROP_POS_FRAMES提取视频帧,可以按照以下步骤进行操作: 导入OpenCV库:import cv2 打开视频文件:video = cv2.VideoCapture('video.mp4')这里的'video.mp4'是视频文件的路径,可以根据实际情况进行修改。 设置要提取的帧位置:frame_position = 100 # 设置要提取的帧位置,这里以100帧为例 video....
文件“videoOperation.py”,第 37 行,在 pos_frame = cap.get(cv2.CV_CAP_PROP_POS_FRAMES) AttributeError: ‘module’ object has no attribute ‘CV_CAP_PROP_POS_FRAMES’
