How to pull multiple ESP32 CAM video streams to a web dashboard on Phoenix

Hi,

I would like if somebody could tell me a starting point or a draft architecture design for what I want to achieve. (Links, documentation, examples, all help). I found already some resources but some are old (2017/18) and others might not be exactly what I need.

Here is description:

I have a raspberry pi 3 B, running Nerves and Phoenix (live).
At the moment I managed to generate a page with some buttons where I can control Sonoff wireless switches via REST API.
Now I would like Phoenix to connect to one, or more, ESP32 CAM which streams a video on its own webserver. I can watch ESP32 CAM video stream on a web browser, therefore I assume I could take that and other streams with a background process and forward them to a Phoenix web Dashboard.

Would it be possible to use LiveView for this, or it does not make sense?
Are there any uptodate library I could start reading about?
What would be the streaming pipeline for this case?

Thank you so much in advance

I will share it here shortly, my teammate has to extract the code from one of our products into a library. We are aiming to follow the same spec as the JS client - although we won’t have all the features to start with. We currently have phx_join, new_msg, phx_reply and disconnect handlers.

EDIT -

Started documenting the specification here - Client for Phoenix Channels · Issue #13 · IoTReady/esp32_firmware_base · GitHub

Feel free to add or comment.

@Snake-Sanders - we have a very early release of the ESP32 client. Please note that response and error handling is still WIP.
