双向对讲

更新时间：2025-12-31 14:54:05

语音通话

双向对讲只在直播时可用

// 导入音视频通话头文件
import { RTCXAudiaVideoService, RTCXAudiaVideoTalk } from 'rtcxsdk'

export interface IAudioVideoTalk {
  /**
   开始通话
   */
  startTalk(): void,
  /**
   结束通话
   */
  endTalk(): void,
}

export interface IAudioVideoTalkListener {
  /**
   音视频通话失败回调

   @param error 错误
   */
  onFailToAudioVideoTalk?: (error: BusinessError<void>|undefined)=>void
}

export enum EAudioVideoTalkType {
  Audio = 0,// 音频通话
  Video = 1 // 视频通话
}


export class AudioVideoTalk implements IAudioVideoTalk {
  private playInfo: IPlayInfo|undefined
  private talkListener: IAudioVideoTalkListener|undefined
  private avTalkType: EAudioVideoTalkType|undefined
  constructor(playInfo: IPlayInfo, avTalkType: EAudioVideoTalkType, talkListener: IAudioVideoTalkListener)
}

调用示例如下:

// 1. 添加监听
audiaListener: RTCXAudiaVideoService.IAudioVideoTalkListener = {
    onFailToAudioVideoTalk: (error: BusinessError<void>|undefined)=>{
      RTCXLogger.i(this.TAG, `对讲发生错误：${error?.code}, ${error?.message}`)
    }
}
// 2. 初始化通话引擎
const playInfo: RTCXMediaType.IPlayInfo = {
      iotId: this.deviceInfo?.iotId!,
      productKey: this.deviceInfo?.productKey!,
      deviceName: this.deviceInfo?.deviceName!,
      lensId: 0,
      streamType: 0,
      deviceType: 0
}
this.audioTalkEngin = new RTCXAudiaVideoTalk.AudioVideoTalk(playInfo,RTCXAudiaVideoService.EAudioVideoTalkType.Audio,this.audiaListener)
// 3. 开始音频通话
this.audioTalkEngin.startTalk()
// 4. 结束音频通话
this.audioTalkEngin.endTalk()

备注：当onFailToAudioVideoTalk:回调error.code = -10023时，代表当前语音对讲通道被其他端占用，应结束对讲。
