Any software that will give a dummy stream until the actual stream begins?

[Prairie Dog]

My problem is that there is a private stream I want to get but for reasons beyond my control it can take up to a couple minutes for the stream to start, and most if not all software times out first. So what I would like is to find a way to request the stream, but then send dummy stream data (could be just a static image at the proper size) back to the calling program until the desired stream arrives, then switch to sending that stream. I hope that makes sense. Basically I am just looking for some way to keep the calling program from timing out because it's not getting any data. Would prefer a Linux solution (or one that will run in Linux) because I don't run Windows.

Will yt-dlp stream a dummy stream to the client (such as VLC) until the actual stream begins? I always thought yt-dlp was for capturing videos on web sites, not for use with live streaming (at least not in the way I need, where it would pass the live stream to another client but substitute a dummy stream until the real one begins).

yt-dlp can be used to capture live streams, if that's not what your after then you might try streamlink

Streamlink looks interesting, I'll have to watch the videos on it. Thanks!
