这样编译可以成功，但是运行如下代码的时候，提示错误，具体如下：
代码：
#include <iostream>
#include <opencv2/opencv.hpp>
cv::Mat frame;
cv::VideoCapture capture;
long g_count = 0;
int main()
{
std::cout<<"open cam "<<std::endl;
if(!capture.open("test.mp4"))
{
std::cout<<"open cam failed"<<std::endl;
//return -1;
}
while(1)
{
std::cout<<"capture frame "<<std::endl;
capture>>frame;
if(frame.cols > 0 && frame.rows > 0)
{
std::cout<<"imshow frame "<<std::endl;
cv::imshow("0",frame);
}
if(cv::waitKey(30)==27) break;
}
return 0;
}

这是错在哪里？gstreamer没装好？
