First make sure that you have correctly installed ffmpeg and other required stuff for opencv 2.3 首先，请确保您已正确安装ffmpeg和其他OpenCV 2.3所需的东西

If Mint has package for opencv 2.3, completely remove opencv from your computer. 如果Mint具有适用于opencv 2.3的软件包，请从计算机中完全删除opencv。 and install it again. 并再次安装。

I was facing the same problem in ubuntu 11.10. 我在ubuntu 11.10中遇到了同样的问题。 If Mint doesn't have OpenCV 2.3 package, re-install opencv 2.3.1 from http://www.marcolancini.it/other/opencv_install_231.php 如果Mint没有OpenCV 2.3软件包，请从http://www.marcolancini.it/other/opencv_install_231.php重新安装opencv 2.3.1 。
