OpenCV ffmpeg错误 [英] OpenCV ffmpeg error

问题描述

在OpenCV中，我使用以下函数从文件创建CvCapture:

In OpenCV I am using the following function to create a CvCapture from a file:

CvCapture * data = cvCreateFileCapture(filename);

这对于带有.avi扩展名的视频文件很好用.当我使用使用rtsp协议的网络摄像机时，出现以下错误:

this works fine for video files with .avi extension. When I use a an internet camera using rtsp protocol I get the following error:

warning: Error opening file (../../modules/highgui/src/cap_ffmpeg_impl.hpp:477)

很显然，编解码器出了点问题.有人知道如何解决吗?由于我是OpenCV的新手，所以宁愿需要逐步说明.

Obviously there is something wrong with the codecs. Anybody knows how to solve it? Would rather need step by step instructions since I am a newbie with OpenCV.

推荐答案

文件名必须看起来像:"C:\\ test.avi"，检查您的filePath

filename must seem like : "C:\\test.avi"，check your filePath
