Video SDK Session Lifecycle (Join, Stream, Render, Leave)

Video SDK Session Lifecycle (Join, Stream, Render, Leave)

Many “video not showing” and “audio not starting” threads are caused by calling APIs out of order.

Canonical Order

Create client
init
join
Get stream (getMediaStream) after join
Start audio/video and render based on events
Leave session and cleanup

Common Gotcha: `getMediaStream()` Timing

On Web, client.getMediaStream() is only valid after join.

Rendering Is Event-Driven

Make sure you:

listen for join/leave events
listen for peer video state changes
attach/detach video elements when peers start/stop video

UI Toolkit Notes

If using UI Toolkit:

let Toolkit manage most lifecycle/rendering
when you need something “custom” (e.g., snapshot, screen-share detection), confirm whether Toolkit exposes that or whether you must use underlying SDK APIs
