Headless jitsi meet on Raspberry pi

Readme.md

Initial code and inspiration from:

• https://code.saghul.net/2017/09/streaming-a-webcam-to-a-jitsi-meet-room/
• https://community.jitsi.org/t/join-meeting-button-on-meet-jit-si-workaround/69788/7
• puppeteer/puppeteer#550

Prepare the PI (using Raspberry PI OS Lite as base):

$ curl -sL https://deb.nodesource.com/setup_14.x | sudo bash -
$ sudo apt update && sudo apt dist-upgrade
$ sudo apt install nodejs
$ sudo apt install --no-install-recommends chromium-browser
$ npm install puppeteer-core

jitsi.js

const puppeteer = require('puppeteer-core');
const readline = require('readline-sync');

// Streams the first webcam in the system to the specified Jitsi Meet room. Audio is currently
// not sent, but it can be easily enabled by disabling the corresponding setting in `meetArgs`.
//
// TODO
//   - Detect end of call to gracefully exit
//   - Send button press notification using Signal, Telegram...
//
// NOTE: only tested on GNU/Linux.

async function main(room, baseUrl='https://meet.jit.si') {
    const chromeArgs = [
        // Disable sandboxing, gives an error on Linux
        '--no-sandbox',
        '--disable-setuid-sandbox',
        // Automatically give permission to use media devices
        '--use-fake-ui-for-media-stream',
        //  You may need to play with these options to get proper input and output
        //'--alsa-output-device=plug:hw:0,1'
        '--alsa-input-device=plug:hw:1',
    ];
    const meetArgs = [
        // Disable receiving of video
        'config.channelLastN=0',
        // Unmute our audio
        'config.startWithAudioMuted=false',
        // Don't use simulcast to save resources on the sender (our) side
        'config.disableSimulcast=true',
        // Disable P2P mode due to a bug in Jitsi Meet
        'config.p2p.enabled=false',
        // Disable prejoin page
        'config.prejoinPageEnabled=false'
    ];
    const url = `${baseUrl}/${room}#${meetArgs.join('&')}`;
    console.log(`Loading ${url}`);

    const browser = await puppeteer.launch({
        args: chromeArgs,
        handleSIGINT: false,
        executablePath: '/usr/bin/chromium-browser',
        ignoreDefaultArgs: ['--mute-audio'],
    });
    const page = await browser.newPage();

    // Manual handling on SIGINT to gracefully hangup and exit
    process.on('SIGINT', async () => {
        console.log('Exiting...');
        await page.evaluate('APP.conference.hangup();');
        await page.close();
        browser.close();
        console.log('Done!');
        process.exit();
    });

    await page.goto(url);
    // Set some friendly display name
    await page.evaluate('APP.conference.changeLocalDisplayName("Doorbell");');
    console.log('Running...');

}

main(process.argv[2] || 'VideoDoorbellTest');

Hey, thanks for this addition to https://code.saghul.net/tag/headless/ and https://gist.github.com/saghul/179feba3df9f12ddf316decd0181b03e, as it got me on to the right track concerning the prejoin page.

Your take:

        // Disable prejoin page
        'config.prejoinPageEnabled=false'

Newer jitsi implementations have changed this, so this is what you need nowadays:

        'config.prejoinConfig.enabled=false'

Have a nice day!
