我在Ubuntu 14.04上使用OpenCV 2.4.8来阅读一些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看起来像这样(它们在某些方法之间是分开的，所以我包括了完成打开和读取框架的所有工作的代码行:
cv::VideoCapture cap;
cap.open (input_path);
success = cap.read (data.frames[i]);
有谁知道我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，但似乎不起作用。
最佳答案
根据我的经验，最简单的解决方案是转换为.avi
无法像.avi一样简单地处理mp4文件似乎是opencv的错
关于c++ - OpenCV无法读取MP4视频，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/32479249/
