How access to video frame in VFW RRS feed

  • Question

  • I record video from camcorder by TV card with function VFW.

    Video is connected like that:

    capwin = capCreateCaptureWindowA(NULL,

    WS_CHILD + WS_VISIBLE + WS_OVERLAPPED,

    x,y,x+dx,y+dy,mywindow,1);

    capDriverConnect(capwin, 0);

    I grab single snapshots like that:

    capCaptureSingleFrameOpen(capwin);

    capCaptureSingleFrame(capwin);

     Is there any access how to get to video frame in buffer (memory) before saving this frame to file and this frame modify - for example write titles and time or convert it to grey scale?

    Thanks T.Franek
