c++ - OpenCV 无法读取 MP4 视频

转载作者：太空宇宙更新时间：2023-11-03 22:55:01

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，但由于某种原因，当我编译和运行该程序时，它在退出前给出了这些错误:

在文件中读取的代码的主要部分如下所示(它们在一些方法之间分开，所以我包含了完成与打开和读取框架有关的所有工作的行:

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读取这些视频？我尝试添加“cap.set(CV_CAP_PROP_FOURCC, CV_FOURCC('H', '2', '6', '4'));”在“cap.open”之前，但这似乎不起作用。

最佳答案

根据我的经验，最简单的解决方案是转换为 .avi不能像.avi一样简单地处理mp4文件，这似乎是opencv的错
