Never used mpeg-TS, only mjpeg. Since you cannot decode it in your browser, my best guess is that you need to decode it inside Node-RED (before you send the images to the dashboard) using:
- ffmpeg (via Exec-node)
- jsmpeg for a full javascript solution (i.e. without any dependencies that you need to install). But will need some programming skills to get this integrated into Node-RED ...
- Others ?
[EDIT] You can also use jsmpeg in your browser (i.e. the dashboard), if you don't want to decode the image in your NodeJs (server-side) Node-RED flow.
But I'm afraid I cannot assist you further with this ...
