Stop HLS - iOS

This could refer to stopping the transmission of an ongoing HLS stream, which would mean the stream is no longer available to viewers.

Stopping HLS

• stopHls() is used to stop interactive livestream of the meeting which can be accessed from the Meeting class.

Example

Swift

  func stopHLS() {
      DispatchQueue.main.async {
          self.meeting?.stopHLS()
      }
  }

Event associated with HLS

• onHlsStateChanged - Whenever meeting HLS state changes, then onHlsStateChanged event will trigger.

• You will get HLS_STOPPING and HLS_STOPPED status on calling stopHls().

note

downstreamUrl is now depecated. Use playbackHlsUrl or livestreamUrl in place of downstreamUrl

Swift

class MeetingViewController: ObservableObject {
    //...
        // Add event listeners and join the meeting
        meeting?.addEventListener(self)
    //...
}

extension MeetingViewController: MeetingEventListener {
    //...
    func onHlsStateChanged(state: HLSState, hlsUrl: HLSUrl?) {
        hlsState = state
        switch (state) {
        case .HLS_STARTING:
            print("HLS is Starting")
        case .HLS_STARTED:
            print("HLS is Started")
        case .HLS_PLAYABLE:
            print("HLS is Playable Now!")
            // on hls started you will receive playbackHlsUrl and livestreamUrl
            let playableURL = hlsUrl?.playbackHlsUrl ?? ""
            let liveStreamURL = hlsUrl?.livestreamUrl ?? ""
        case .HLS_STOPPING:
            print("HLS is Stopping")
        case .HLS_STOPPED:
            print("HLS is Stopped")
        @unknown default:
            fatalError("Unknown HLS State")
        }
    }
}
