I have to show running addwords on TV chanel.

So I publish stream through publisher on server side and to this stream overlay text, images etc. on full screen size.

This is working if in publish add packets from another stream, if stream is empty so I can’t overlay image.

I’m using Wowza Streaming Engine 4.0.3

Take a look at [ModuleLoopUntilLive](https://www.wowza.com/docs/how-to-loop-a-pre-roll-until-a-live-stream-starts-loopuntillive), which you can configure to show a loop when the live stream goes down, and show the live stream again when it is started. It is dependent on a proper IMediaStreamActionNotify.Publish() and IMediaStreamActionNotify.UnPublish() events.
