</template>

类型定义

export interface UseDevicesListOptions extends ConfigurableNavigator {
  onUpdated?: (devices: MediaDeviceInfo[]) => void
  /**
   * Request for permissions immediately if it's not granted,
   * otherwise label and deviceIds could be empty
   *
   * @default false
   */
  requestPermissions?: boolean
  /**
   * Request for types of media permissions
   *
   * @default { audio: true, video: true }
   */
  constraints?: MediaStreamConstraints
}
export interface UseDevicesListReturn {
  /**
   * All devices
   */
  devices: Ref<MediaDeviceInfo[]>
  videoInputs: ComputedRef<MediaDeviceInfo[]>
  audioInputs: ComputedRef<MediaDeviceInfo[]>
  audioOutputs: ComputedRef<MediaDeviceInfo[]>
  permissionGranted: Ref<boolean>
  ensurePermissions: () => Promise<boolean>
  isSupported: Ref<boolean>
}
/**
 * Reactive `enumerateDevices` listing available input/output devices

 * @see https://vueuse.org/useDevicesList
