TypeError: descriptor 'open' for 'cv2.VideoCapture' objects doesn't apply to a 'str' object

这个错误是因为在使用cv2.VideoCapture函数时，传入的参数类型不正确。根据引用\[1\]和引用\[2\]的信息，可以看出，当视频文件路径包含中文字符时，会导致这个错误。解决方法是将路径转换为utf-8编码，即使用`cv2.VideoCapture(absolute_path.encode('utf-8'))`来代替`cv2.VideoCapture(absolute_path)`。这样可以确保路径的正确性。另外，根据引用\[3\]的信息，还有可能是缺少处理视频文件所需的dll文件，可以尝试将opencv文件夹中的`opencv_ffmpeg.dll`文件复制到Python文件夹目录中。这样应该能够解决这个错误。
