Hy, I’m new about Milestone features, and I would like to know if is it possible to overlay matadata or text in playback mode?

My idea is to insert metadata during playback view.

is there any sdk Sample or plug in where to have a look?

Thanks a lot,

Yes. There is no sample but it is possible.

The Smart Client overlay on Event plugin sample shows how to do overlay. This sample lacks two things:

It does not work in playback mode. The sample would need to be modified to base the overlay on

abstract DateTime VideoOS.Platform.Client.ImageViewerAddOn.PlaybackImageDateTime

[get]

or

abstract RecordedImageReceivedHandler VideoOS.Platform.Client.ImageViewerAddOn.RecordedImageReceivedEvent

or similar.

It works with events but not metadata. If you mean metadata in general you might have it there, but if you mean metadata as data that has been recorded by the XProtect VMS using a metadata provider (eg. the Bounding Box metadata provider sample) you will need to read it. The reading of the metadata you can see by exploring the Metadata Playback Viewer sample.

I’m going to try,

Thanks you are precise and punctual as always.
