FAQ

What is WebRTC?

WebRTC is a free and open source project that enables web browsers and mobile devices to provide simple realtime communication. This means that app features like peer-to-peer video conferencing can easily be integrated into a web page. A browser-based video chat can be engineered rapidly with HTML and JavaScript.

What do I need to do to run LiveSmart Video Chat?

You need a web server with a) installed Node.js or b) Root access and SSL certificates. After that follow the install instructions from here.

What is the best server configuration for LiveSmart?

You can set it in any Linux or Windows server, though you need:
- SSL enabled;
- Root access;
- Access to the certificates and keys;
- Please note that most probably shared hosting will not fit your need. Use VPS or dedicated hosting.

How many visitors at once can I have?

- For 1:1 video sessions, theoretically the number of concurrent sessions can be unlimited. I have tested with 50 1:1 video sessions on the demo server. It is scalable, so it can maintain much more.

For multi user video session, the number of participants in each session is limited by client-side bandwidth, device, and CPU limitations for processing vast amounts of video and audio streams. Five to eight participants in a single video conference is a reasonable number. (#1 for rooms at once is valid here)

For the broadcasting session there is one or two broadcaster and many viewers that are subscribing to their video and audio stream. I have clients that are using the broadcasting feature for online lessons for 30-40 viewers, but this number is also scalable and for sure it can maintain more attendees.

I don't see the button?

Make sure the backend is properly installed and that the port for WSS is the same as in the /config/config.json file. Check the code snippet that you added to the site has data-source_path correctly added and that <div id="nd-widget-container" class="nd-widget-container"></div> is present in your HTML.

I have set everything correctly, but when I open agent page, it gives WSS error

Probably the port is closed. Check with the management console of your server to open the WSS port

I got error...

PermissionDeniedError or Could not connect stream
The errors are most common if your browser has no access to web camera or microphone
- Make sure you are using SSL;
- Make sure you have granted permissions to microphone and camera;
- If you are using Firefox or Safari, make sure there is no other app that is accessing your camera or microphone;

I have some additional questions, requirements or something is not working for me?
