RTCStream Class Properties - Android

id

• type: String

• id is the id of the stream. It is also the key of the stream in participant.streams.

---

kind

• type: MediaType

• kind is the type of stream:

  • MediaType.AUDIO: the microphone.
  • MediaType.VIDEO: the camera.
  • MediaType.SHARE: the screen share.
  • MediaType.SHARE_AUDIO: the audio shared with the screen, sent by participants on other platforms. An Android sharer mixes it into the microphone stream instead.

---

participantId

• type: String

• participantId is the ID of the participant who publishes the stream.

---

track

• type: MediaStreamTrack from the videosdk.org.webrtc package

• track is the media track of the stream. Reading it again returns the same track.

• For MediaType.VIDEO and MediaType.SHARE, it is a VideoTrack. Cast it and pass it to VideoView.addTrack() to render it. Don't draw it with addSink(): the track can be a handle whose addSink() does nothing.

• For MediaType.AUDIO and MediaType.SHARE_AUDIO, it is a handle, and casting it to VideoTrack throws. The SDK plays remote audio itself, so setVolume() and setEnabled() on it don't change playback. To stop receiving a participant's audio, call pause() on the stream.

Example

import videosdk.org.webrtc.VideoTrack

class ParticipantViewListener(private val videoView: VideoView) : ParticipantEventListener() {
    override fun onStreamEnabled(stream: RTCStream) {
        if (stream.kind == MediaType.VIDEO) {
            videoView.addTrack(stream.track as VideoTrack)
        }
    }
}
