VideoPresentationService class Services

The VideoPresentationService allows sharing videos during a conference. To present a video, a conference participant needs to provide the URL of the video file. We recommend sharing files in the MPEG-4 Part 14 or MP4 video formats.

The video presentation workflow:

  1. The presenter calls the start method to start the video presentation. This method automatically starts playing the shared video file.

  2. All participants receive the VideoPresentationEventNames.videoPresentationStarted event.

  3. The presenter can call the pause method to pause the shared video. In such a situation, all conference participants receive the VideoPresentationEventNames.videoPresentationPaused event.

  4. The presenter can call the play method to resume the paused video. In this situation, all conference participants receive the VideoPresentationEventNames.videoPresentationPlayed event.

  5. The presenter can call the seek method to navigate to a specific section of the shared video. This method applies the provided timestamp. After calling the seek method, all conference participants receive the VideoPresentationEventNames.videoPresentationSought event and watch the video from the specified timestamp.

  6. The presenter calls the stop method to stop the video presentation.
