Voici un bout de code en vba qui met toutes les vidéos de la présentation en démarrage automatique (par défaut, elles démarrent au clic).
Sub triggerAuto()
Dim counter As Integer
counter = 0
types = ""
For Each s In ActivePresentation.Slides
For Each ms In s.TimeLine.MainSequence
'check if it is a media (type = 16)
If ms.Shape.Type = 16 Then
'check if it is a video (mediatype = 3)
If ms.Shape.MediaType = 3 Then
'set start as automatically
ms.Timing.TriggerType = msoAnimTriggerAfterPrevious
counter = counter + 1
End If
End If
Next ms
Next s
MsgBox (counter)
End Sub
