OpenCV无法读取MP4视频

Question

我在Ubuntu 14.04上使用OpenCV 2.4.8读取一些MP4视频。 该程序可以在Mac和其他Linux机器上运行，但是由于某些原因，当我编译并运行该程序时，在退出之前会给我这些错误：

正在文件中读取的代码的主要部分如下所示（它们在某些方法之间是分开的，因此我包括了以下行，这些行完成了打开和读取框架的所有工作：

cv::VideoCapture cap;
cap.open (input_path);
success = cap.read (data.frames[i]);

有谁知道我如何才能让我的程序正确阅读这些视频？ 我试图添加“ cap.set（CV_CAP_PROP_FOURCC，CV_FOURCC（'H'，'2'，'6'，'4'））;“ 在“ cap.open”之前，但似乎不起作用。

根据我的经验，最简单的解决方案是将其转换为.avi似乎无法像.avi一样简单地处理mp4文件是opencv的错
