Decrease external video's volume on speak

What is it?

This plugin is one of the official bbb plugins. It basically decreases the external video's volume when a user is speaking in the meeting.

Building the Plugin

To build the plugin for production use, follow these steps:

cd $HOME/src/plugin-decrease-volume-on-speak
npm ci
npm run build-bundle

The above commands will generate the dist folder, containing the bundled JavaScript file named DecreaseVolumeOnSpeak.js. This file can be hosted on any HTTPS server along with its manifest.json.

If you install the plugin separated from the manifest, remember to change the javascriptEntrypointUrl in the manifest.json to the correct endpoint.

To use the plugin in BigBlueButton, send this parameter along in create call:

pluginManifests=[{"url":"<your-domain>/path/to/manifest.json"}]

Or additionally, you can add this same configuration in the .properties file from bbb-web in /usr/share/bbb-web/WEB-INF/classes/bigbluebutton.properties
