enumerateAudioPlaybackDevices method

FutureOr<ByteRTCDeviceCollection> enumerateAudioPlaybackDevices()

@detail api @author dixing @brief 获取当前系统内音频播放设备列表。 @return 所有音频播放设备的列表，参看 ByteRTCDeviceCollection{@link #ByteRTCDeviceCollection}。
等待超时后会返回空列表。超时时间默认为 10 s。建议通过 rtcEngine:onAudioDeviceStateChanged:device_type:device_state:device_error:{@link #ByteRTCEngineDelegate#rtcEngine:onAudioDeviceStateChanged:device_type:device_state:device_error} 监听到 ByteRTCMediaDeviceListUpdated 后，再次调用本接口获取。 @note 你可以在收到 rtcEngine:onAudioDeviceStateChanged:device_type:device_state:device_error:{@link #ByteRTCEngineDelegate#rtcEngine:onAudioDeviceStateChanged:device_type:device_state:device_error} 了解设备变更后，重新调用本接口以获得新的设备列表。

Implementation

FutureOr<ByteRTCDeviceCollection> enumerateAudioPlaybackDevices() async {
  final result = await nativeCall('enumerateAudioPlaybackDevices', []);
  return packObject(
      result,
      () => ByteRTCDeviceCollection(
          const NativeClassOptions([], disableInit: true)));
}
