嗨伙计们。我正在尝试使用opencv库编译C ++代码，但我正面临挑战。所有的图像处理，即imread，imshow和它们都工作正常但是当我尝试使用VideoCapture加载视频文件时，我的c ++代码并没有在linux环境中的eclipse luna中构建。我添加了一个小代码片段，仅用于使用VideoCapture测试视频支持，但它无法正常工作。有人可以帮我解决这个问题。这是eclipse控制台和小型c ++代码片段的输出。
#include <opencv2/opencv.hpp>

#include <opencv2/video/video.hpp>
using namespace cv;
using namespace std;
int main(){
VideoCapture capture("traffic.mp4");
}
