现有一些图片按顺序放置在一文件夹jogging1\下，如图：

需要将其合并转换为一个视频。

示例：

环境：Win7+OpenCV3+VS2012


#include<opencv2/opencv.hpp>
#include <stdio.h>
#include <io.h>
#include <string>
#include <iostream> 
#include <fstream> 
using namespace std;
using namespace cv;
int main()
{
  _finddata_t FileInfo; 
  //读取图片所在的路径
  string inPath = "E:\\image\\yu\\jogging1\\"; 
  string strfind = inPath + "*";
  long Handle = _findfirst(strfind.c_str(), &FileInfo);
  char filename[300];
  Mat src;
  if (Handle == -1L)
  { 
    cerr << "can not match the folder path" << endl; 
    exit(-1);
  }
  Mat frame;
  Mat src0 = imread("E:/image/yu/jogging1/0000.jpg");
  Size size = src0.size();
  VideoWriter writer;
  writer.open("jogging.avi", CV_FOURCC('M', 'J', 'P', 'G'), 25, size, true);
  do{
    //判断是否有子目录
    if (FileInfo.attrib & _A_SUBDIR) 
    { 
      if ((strcmp(FileInfo.name, ".") != 0) && (strcmp(FileInfo.name, "..") != 0)) 
      { 
        inPath += FileInfo.name;
        cout <<inPath<<endl; 
      }
    }
    else
    {
      cout <<inPath<<FileInfo.name<<endl;
      //读取图片所在的路径
      string path = "E:/image/yu/jogging1/" + (string)FileInfo.name;
      src = imread(path);
      imshow("input", src);
      writer.write(src);
      waitKey(1);
    } 
  } while (_findnext(Handle, &FileInfo) == 0); 
  _findclose(Handle);  
  return 0; 
}
