Feature Request: Option to send/receive messages via javascript BroadcastChannel inside the OBS browser

[istvanmate]

Background

I have several html sources and custom browser docks which communicate amongst themselves via BroadcastChannel messages. Does SceneSwitcher support this? If not, would be a nice addition.

Solution

ability to tap into javascript broadcast channels:

var bc = new BroadcastChannel('channel-name')

send messages with

bc.postMessage('message-to-send')

receive messages with

bc.onmessage = function(message){
  if(message == 'message-to-send') {
    ...
  }
}

Alternatives

Anything else we should know?

Unfortunately, I am not too familiar with the capabilities of the OBS browser source.
But as I understand it - which might be incorrect - I don't think the advanced scene switcher plugin will be able to "inject" itself into the chromium environment easily.

The advanced scene switcher does however offer the option to send / receive http / websocket requests.
Maybe that would be an alternative for what you are trying to do?

Yeah, BroadcastChannel is (was) the most convenient way to communicate between loaded html documents, but looks like, I will have to use OBS websocket's BroadcastCustomEvent as bridge between them, if I want communication from/to outside.
