Does Zoom use WebRTC or WebSockets?

Zoom is using WebRTC. Somewhat. With a data channel. To handle live video streams, with their previous WebSocket architecture as fallback.

Is WebRTC the same as WebSockets?

✅ What is the difference between WebRTC and WebSockets? While both are part of the HTML5 specification, WebSockets are meant to enable bidirectional communication between a browser and a web server and WebRTC is meant to offer real time communication between browsers (predominantly voice and video communications).

Does Zoom use Websocket?

Zoom doesn’t use WebRTC (which the article is about). They use websockets to send media through the pipes and decode using a webgl shader or similar. Zoom has to be using h264 under the covers.

Is WebRTC faster than Websocket?

Websockets are highly faster than WebRTC !

Which encoder does zoom use?

MPEG-4
Bitrate Encoding Zoom figured out the issues with traditional Video conferences of being jittery over bad network environments and required a lot of CPU intensive resources. So Zoom chose to use H. 264 Annex G(SVC) codec over H. 264 (MPEG-4 Part 10).

Are WebSockets fast?

As is clear from the table, for our use case Websocket is expected to be about 5-7 times faster than plain HTTP.

Does Zoom use h264?

Zoom figured out the issues with traditional Video conferences of being jittery over bad network environments and required a lot of CPU intensive resources. So Zoom chose to use H. 264 Annex G(SVC) codec over H. 264 (MPEG-4 Part 10).

What is the difference between WebRTC and webzoom?

Zoom might be working through external remote servers for that same session while WebRTC is going peer to peer on the local network. Servers behave differently than clients, so the results seem somewhat “off” In other scenarios, Zoom might actually be better than WebRTC

What is the difference between HTTP and WebSockets?

HTTP vs Websockets: A performance comparison. In many web applications, websockets are used to push messages to a client for real-time updates. One of the more interesting and often overlooked features is that most websocket libraries also support directly responding to websocket messages from a client (acknowledgements in message queue-speak).

What do you think about the design of WebRTC?

The overall design is quite interesting. It uses WebSockets to transfer the media which is certainly not an optimal choice. It is similar to using TURN/TCP in WebRTC — it has a quality impact and will not work well in quite a number of cases.

Can we replace WebSockets with WebRTC?

So WebRTC can’t really replace WebSockets. Now, once the connection is established between the two peers over WebRTC, you can start sending your messages directly over the WebRTC data channel instead of routing these messages through a server. In a way, this replaces the need for WebSockets at this stage of the communications.
