const {
  videoInputs: cameras,

} = useDevicesList({
  requestPermissions: true,
})
const currentCamera = computed(() => cameras.value[0]?.deviceId)
const currentMicrophone = computed(() => microphones.value[0]?.deviceId)

const { stream } = useUserMedia({
  videoDeviceId: currentCamera,
  audioDeviceId: currentMicrophone,
})
