  var shape = objSlides.Shapes.AddMediaObject2(@"C:\\Users\\Rajan\\Downloads\\sample-5s.mp4", MsoTriState.msoTrue, MsoTriState.msoFalse, 10, 10);

Anyone please help me to suggest any property name which provide running or stop status of mp4 on current slide .

Answer 1

The PowerPoint object model does not provide any COM methods to play and stop an embedded video. You can try using Windows API functions or Microsoft Active Accessibility to simulate clicks to start the video, but that is not a trivial task.

For example, in VBA you could use the SendKeys method:

Sub Test()
  Application.ActivePresentation.Slides(1).Shapes(1).Select
  SendKeys "%p", True
End Sub
