DirectShow採集核心代码：

创建线程调用该函数，採集图像通过x264解码封装rtmp协议包。推送至FMSserver，可实现视频直播

UINT __stdcall StartVideo(void *c){	CVideoConf *conf = (CVideoConf *)c;	int vid = conf->code;	CString strurl(conf->rtmpurl);	CWnd *pW = conf->pW;	CCameraDS  camera;	if (!camera.OpenCamera(0,false));	{  		TRACE("OpenCamera error.....");  	}	while(true)	{		CvvImage cimg;		CRect rect;				IplImage *m_Frame ;		BYTE *data1 =  camera.QueryFrame(); 		m_Frame = cvCreateImageHeader(cvSize(320,240),IPL_DEPTH_8U,3);		m_Frame->origin = 1;		cvSetData(m_Frame,data1,320*3);		CDC *pDC = pW->GetDC();                                                        		HDC hDC  = pDC->GetSafeHdc();		pW->GetClientRect(&rect); 		cimg.CopyOf((IplImage *)m_Frame); //复制图片		cimg.DrawToHDC(hDC, &rect);	 //显示指定区域		HWND hWnd = pW->GetSafeHwnd();                                  		ReleaseDC(hWnd,hDC); 	}	return 0;	}
