Hello, I think you can use the useVLC in embedded mode

In recent forks of MMM-RTSPStream, VLC can be embedded into the browser view with an iframe or HTML5 video tag, which respects DOM positioning. Check the fork you’re using. If it’s still spawning standalone VLC, look for configuration like:
localPlayer: ‘ffmpeg’ // instead of ‘vlc’

Some forks added ffmpeg or jsmpeg options to push the stream into a element.
