Learning OpenCV 2-3 视频播放控制

这里的程序怎么运行都没办法调通，添加视频地址后运行报错：

opencv frames 451 w 320 h 240  Couldn’t open the input file 

顺着报错的信息从代码里找，原来是这里：  frames = getAVIFrames(argv[1]);  //This is a hackbecause on linux,gettingnumber of frames often doesn't work

再看开始的部分，作者有介绍：/＊We tried to at least find number of frames using the "getAVIFrames" hack below.  Terrible.  But, this file shows something of how to put a slider up and play with it.  Sorry. */

既然是平台的问题，那就直接注释掉好了，  // frames = getAVIFrames(argv[1]);      

然后运行，成功。
