我在Ubuntu 14.04上使用OpenCV 2.4.8来读取一些MP4视频。该程序适用于Mac和其他Linux机器，但出于某种原因，当我编译并运行程序时，它会在退出之前给出这些错误：

在文件中读取的代码的主要部分看起来像这样（它们在某些方法之间分开，所以我已经包含了与打开和读取框架所做的所有工作的行：
cv::VideoCapture cap;
cap.open (input_path);
success = cap.read (data.frames[i]);
有谁知道如何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，但似乎没有用。
答案 0 :(得分：1)
根据我的经验，最简单的解决方案是转换为.avi 似乎是opencv的错误，它无法像.avi一样处理mp4文件
