How live demos work
The live demo system uses WebRTC for real-time video streaming between the presenter (builder) and the event screen:- A builder requests to present their project
- The event manager approves or rejects the request
- Once approved, the builder starts their WebRTC stream from their browser
- The manager views and controls the live stream on the event management page
- Optionally, the demo is recorded for later review
Presentation requests
When builders request to present a live demo, their requests appear in the queue:| Field | Description |
|---|---|
| Project name | The project being presented |
| Presenter | The builder requesting to present |
| Status | Request status: Pending, Approved, Rejected, or Live |
Approving or rejecting requests
Approve or reject
Click Approve to allow the builder to start streaming, or Reject to decline the request.
Managing the presentation queue
The presentation queue shows all approved demos in order. As the event manager, you control the flow of presentations:- Reorder presentations — drag and drop to change the presentation order
- Start next demo — move to the next builder in the queue
- Remove from queue — remove a demo if the team is no longer available
Viewing the live stream
When a builder is presenting, the live stream appears on the Live Demos page. The WebRTC stream provides:- Real-time video and audio from the presenter’s browser
- Low-latency streaming suitable for projecting to event screens
- Stream controls — mute, pause, or end the stream
Both the presenter and viewer need a modern browser with WebRTC support. Chrome, Firefox, Safari, and Edge all support WebRTC.
Recording demos
Demo presentations can be recorded for later review:- Start recording — click the record button while a demo is live
- Stop recording — end the recording when the presentation finishes
- View recordings — access saved recordings from the Live Demos page after the event
