Question

作为我之前问题的后续内容，我能够解决

import cv2 import libardrone.libardrone

我重新安装了opencv，我意识到文档不正确;应该是

import libardrone.ardrone

解决这两个问题让我能够尝试这里给出的track.py：https://github.com/JJLewis/ColorTracking-ARDrone2.0-Python。

即使我正确安装了ffmpeg，运行track.py也会出现以下错误。

作为初学者，我在解决这些问题时遇到了困难。我的规范如下：Mac 10.12，Python 2.7.14和OpenCV 3.3.0_3。

安装时未安装FFMPEG
