Please check if the UniqueId and OfficeInteropShapeId properties from the IShape interface are suitable for your goals.
I was able to reproduce the exception with all four presentations.
The UniqueId and OfficeInteropShapeId properties are unique within a presentation and a slide, respectively. Could you please describe your unique id requirements for video shapes?
I just need to know how many times a video is used in a videoshape.
Because a video could have been inserted more than once under different names : basically after renaming
I disagree The UniqueId and OfficeInteropShapeId properties are unique within a presentation and a slide
By simple manipulations, they can be easily the same.
