ffmpeg实现windows桌面采集

利用ffmpeg实现桌面采集功能，采集桌面后进行解码，图像转换为YUV420P格式，在经过h264编码，最后通过网络TCP协议进行发送。代码可以编译，在没有网络接收服务器的情况下，可将编码后的packet保存成本地的.h264文件

// capture.cpp : 定义控制台应用程序的入口点。
//

#include “stdafx.h“
#include “ff_capture.h“

int _tmain（int argc _TCHAR* argv[]）
{
	ff_capture* pcapture = new ff_capture（）;
	pcapture->ff_init（）;
// 	while（1）
// 	{
// 		Sleep（10）;
// 	}
	return 0;
}
