Question 1

What is WebRTC Simulcast?

Accepted Answer

WebRTC Simulcast is a technique that allows sending different versions of the same video stream at various resolutions and bitrates. The receiving device or media server picks the best version based on network conditions.

Question 2

How does WebRTC Simulcast improve video quality?

Accepted Answer

It prevents buffering and lag by dynamically adjusting the video stream to match the recipient's bandwidth and processing power.

Question 3

Can WebRTC Simulcast be used for gaming streams?

Accepted Answer

Yes. It helps deliver adaptive-quality streams for game streaming services, preventing lag spikes for viewers on slow connections.

Question 4

Is WebRTC Simulcast better than Adaptive Bitrate Streaming?

Accepted Answer

For real-time communication, yes. Simulcast adapts instantly, while Adaptive Bitrate Streaming (ABR) is better suited for pre-recorded video delivery.

Question 5

How do I test WebRTC Simulcast performance?

Accepted Answer

Use tools like Wireshark, WebRTC internals, or browser developer tools to inspect multiple video layers being sent.
