HarmonyOS 鸿蒙Next应用中如何使用avplayer同时播放两个音频

我这边测试创建2个avplayer实例，可以同时播放。您提供下您那边的代码，方便我们排查问题，以下是我的代码您参考。

import { media } from '@kit.MediaKit';
import { BusinessError } from '@kit.BasicServicesKit';

const TAG = 'AVPlayerDemo';

@Component
struct AVPlayerDemo {
  private surfaceId: string = ''; // surfaceId，用于关联XComponent与视频播放器
  private mXComponentController: XComponentController = new XComponentController();
  private avPlayer: media.AVPlayer | undefined = undefined;
  private surfaceId1: string = ''; // surfaceId，用于关联XComponent与视频播放器
  private mXComponentController1: XComponentController = new XComponentController();
  private avPlayer1: media.AVPlayer | undefined = undefined;

  aboutToAppear(): void {
    //创建avplayer
    this.initAvPlayer()
    //创建avplayer
    this.initAvPlayer1()
  }

  initAvPlayer() {
    media.createAVPlayer().then((avPlayer: media.AVPlayer) => {
      this.avPlayer = avPlayer;
      this.playerCallback(this.avPlayer);
      this.avPlayer.url = 'https://mmslivef.scgchc.com/live/1219.m3u8?auth_key=1735893693-0-0-0d1a6d5f60e5d9105497f7a344b7ca59';
    })
  }

  initAvPlayer1() {
    media.createAVPlayer().then((avPlayer: media.AVPlayer) => {
      this.avPlayer1 = avPlayer;
      this.playerCallback(this.avPlayer1);
      this.avPlayer1.url = 'https://www.w3school.com.cn/example/html5/mov_bbb.mp4';
    })
  }

  // 注册avplayer回调函数
  playerCallback(avPlayer: media.AVPlayer) {
    avPlayer.on('timeUpdate', (time: number) => {
      console.info(TAG, 'AVPlayer timeUpdate. time = ' + time / 1000);
    })
    // error回调监听函数,当avPlayer在操作过程中出现错误时调用 reset接口触发重置流程
    avPlayer.on('error', (err: BusinessError) => {
      console.error(TAG, `Invoke avPlayer failed, code is ${err.code}, message is ${err.message}`);
      avPlayer.reset(); // 调用reset重置资源，触发idle状态
    })
    // 状态机变化回调函数
    avPlayer.on('stateChange', async (state: string, reason: media.StateChangeReason) => {
      switch (state) {
        case 'idle': // 成功调用reset接口后触发该状态机上报
          console.info(TAG, 'AVPlayer state idle called.');
          break;
        case 'initialized': // avplayer 设置播放源后触发该状态上报
          console.info(TAG, 'AVPlayer state initialized called.');
          if (avPlayer == this.avPlayer) {
            avPlayer.surfaceId = this.surfaceId;
            avPlayer.prepare();
          } else {
            avPlayer.surfaceId = this.surfaceId1;
            avPlayer.prepare();
          }
          break;
        case 'prepared': // prepare调用成功后上报该状态机
          console.info(TAG, 'AVPlayer state prepared called.');
          break;
        case 'completed': // prepare调用成功后上报该状态机
          console.info(TAG, 'AVPlayer state completed called.');
          break;
        case 'playing': // play成功调用后触发该状态机上报
          console.info(TAG, 'AVPlayer state playing called.');
          break;
        case 'paused': // pause成功调用后触发该状态机上报
          console.info(TAG, 'AVPlayer state paused called.');
          break;
        case 'stopped': // stop接口成功调用后触发该状态机上报
          console.info(TAG, 'AVPlayer state stopped called.');
          break;
        case 'released':
          console.info(TAG, 'AVPlayer state released called.');
          break;
        default:
          console.info(TAG, 'AVPlayer state unknown called.');
          break;
      }
    })
  }
