You can publish a stream that uses a video view of your screen (instead of a camera) as the source. A client connected to the session can subscribe to the stream (and view it), just as they would subscribe to a stream that uses a camera as the source.
This topic includes the following sections:
To use the device's screen, instead of a camera, as the video source, use the PublisherKit class to use a custom video capturer. For a code sample, see the screen-sharing activity in the samples directory of the SDK.
setPublisherVideoType(PublisherKit.PublisherKitVideoType type) property of the Publisher object and pass in
PublisherKit.PublisherKitVideoTypePublisherKitVideoTypeScreen. This flags the
published stream as having a screen-sharing video source (instead of a camera).
Before you publish a screen-sharing stream that uses the screen video type in a routed session, you should call the
method for the PublisherKit object and pass in
false. This disables the audio-only
fallback feature, so that the video does not drop out in subscribers. See
The OpenTok Media Router and media
The Stream object contains a
videoType property. This can be set to one of the following values, defined in the Stream.StreamVideoType enum:
StreamVideoTypeCamera— a standard video stream that uses a camera as the video source
StreamVideoTypeScreen— a screen sharing video stream
StreamVideoTypeCustom— a stream published by a web client using an HTML VideoTrack element as the video source
You can subscribe to a stream that uses a screen-sharing video source in the same way that you subscribe to a stream that uses a camera as the source. See Subscribing to streams.
