Presentation - Screen share
Presentation means sharing a screen of a user (presenter) to show a material such as slides to the other call peers. This page describes how to use the presentation function based on the call type.
| Supported call type | Minimum SDK version |
|---|---|
| 1-to-1 call, group call (conference) | WebPlanetKit 3.1 |
- Currently, the presentation feature is not supported in mobile environments.
- PlanetKit uses HD resolution in its presentation feature, so it can provide an optimized service when the client's network conditions meet or exceed the recommended bandwidth.
1-to-1 call presentation
To start or end a presentation in a 1-to-1 call, use startMyScreenShare() or stopMyScreenShare() of Call.
