IVMRWindowlessControl:: RepaintVideo

[P e t e r]

Using DirectShow I have made a program that captures a video stream and writes the data to screen and to disk. Rendering to screen is done by using IVMRWindowlessControl. Problems occur when the desktop is locked, e.g. by the screensaver. After unlocking, the rendering part of my application is gray. Calling IVMRWindowlessControl:: RepaintVideo refreshes this rendering part but resets the framecounter and the video contents. Any ideas how to solve this problem? Best regards, Peter

can you get a handle to the window and call InvalidateRect BOOL InvalidateRect( HWND hWnd, // handle to window CONST RECT* lpRect, // rectangle coordinates BOOL bErase // erase state );
