目前，amazon-kinesis-video-streams-webrtc-sdk-js支持的javascript版本为ECMAScript 2015（即ES6）或更高版本。另外，该SDK支持的AWS Kinesis Video Client SDK版本为v2.x。如果您使用的是v3.x版本，您需要降级AWS Kinesis Video Client SDK版本以兼容该SDK。

以下是一个简单的示例，展示了如何使用amazon-kinesis-video-streams-webrtc-sdk-js创建一个视频流：

// 引入SDK库
const AWS = require('aws-sdk/global')
const KinesisVideo = require('aws-sdk/clients/kinesisvideo')
const KinesisVideoSignalingChannels = require('aws-sdk/clients/kinesisvideosignalingchannels')
const KinesisVideoSignalingChannelsClient = require('amazon-kinesis-video-streams-webrtc-sdk-js').KinesisVideoSignalingChannelsClient
const KinesisVideoStream = require('amazon-kinesis-video-streams-webrtc-sdk-js').KinesisVideoStream
const SignalingClient = require('amazon-kinesis-video-streams-webrtc-sdk-js').SignalingClient
const AWSKinesisVideoSignalingChannels = require('aws-sdk')
AWSKinesisVideoSignalingChannels.Signers.V4.prototype.serviceName = 'kinesisvideo'

// 声明一些变量
let signalingClient
let channelARN
let localStream

// 获取信令通道ARN
const getChannelARN = async (channelName, region) => {
  const kinesisVideo = new KinesisVideo({ region })

  const { ChannelInfoList } = await kinesisVideo.listSignalingChannels({ MaxResults: '1' }).promise()

  if (ChannelInfoList.length > 0) {
    const { ChannelARN } = await kinesisVideo.describeSignalingChannel({
      ChannelName: channelName
    }).promise()
    return ChannelARN
  }

  const { ChannelARN } = await kinesisVideo.createSignalingChannel({
    ChannelName: channelName
  }).promise()

  return ChannelARN
}

// 获取本地视频流
const getLocalStream = async () => {
  const mediaDevices
