DirectShow採集核心代碼：

創建線程調用該函數，採集圖像通過x264解碼封裝rtmp協議包。推送至FMSserver，可實現視頻直播 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); //復制圖片cimg.DrawToHDC(hDC, &rect); //顯示指定區域HWND hWnd = pW->GetSafeHwnd(); ReleaseDC(hWnd,hDC); }return 0; }

Opencv採集核心代碼：

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....."); }CvCapture* pCapture = cvCreateCameraCapture(0); //opencv打開視頻 while(true){CvvImage cimg;CRect rect;IplImage *m_Frame=cvQueryFrame( pCapture );//opencv捕獲幀 CDC *pDC = pW->GetDC(); HDC hDC = pDC->GetSafeHdc();pW->GetClientRect(&rect); cimg.CopyOf((IplImage *)m_Frame); //復制圖片cimg.DrawToHDC(hDC, &rect); //顯示指定區域HWND hWnd = pW->GetSafeHwnd(); ReleaseDC(hWnd,hDC); }
