Not an easy task - see http://stackoverflow.com/questions/3752016/drawing-on-video-within-c-sharp for suggestions.

The major problem is that Video is, most likely, DirecX. The answer depends on what UI library do you use. This is very difficult in Forms (you would need to use DirectX API on lower level) and fairly simple in WPF.

You can easily do it, but this is easy only if you use WPF. In simplest case, put video in some parent container, a panel. On top of it, put some line objects in the same panel.

It could be the object of the class System.Windows.Shapes.Line:

If could be some other Shape:

Optionally, to allow you to freely manipulate coordinates and parameters of your shapes could be placing of video and shapes in System.Windows.Controls.Canvas:
http://msdn.microsoft.com/en-us/library/system.windows.controls.canvas.aspx[^].

For video, you would use the instance of System.Windows.Controls.MediaElement:
