we will leave aside then since it works like that.

that's exactly what I would like (and probably many more). Here is an example of my dashboard:

_it is a global view of all the sensors in the house (water heater, swimming pool, etc.)_

On the left we see that a person has been detected at the portal.[object detection project here](https://discourse.nodered.org/t/object-detection-using-node-red-contrib-tfjs-coco-ssd/22931/52)  
And on the right the streaming of the portal camera. (the cameras are under tabs that you can unfold and automatically launch the rtsp stream).

Fortunately, I chose the camera `stream = 1` to reduce the processor load. For example if I run 4 cameras at the same time I have 25% cpu load (RPI 3b)

If I click on the camera, I switch to `stream = 0` (1080p) on a full page (all other streams are stopped), the cpu is at 40%

Not bad : Makes me go from 40% to 25% cpu while losing a bit in quality (960x540px).

I failed to get it to work by adding it in my current command line:

- the pipe2jpeg node announces : "pipe2jpeg: input must be a buffer"
- if I remove pipe2jpeg : "unrecognized image format"

Are you thinking of doing it? It would be a terrible step forward.
