双向对讲

更新时间：2026-10-29 10:05:40

语音通话

双向对讲只在直播时可用。

双向对讲接口与【通用版-双向对讲】相同，区别在于构建 IPlayInfo 通话对象时，需要设置 deviceType = 1，即专属版设备。

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

通话对象

const playInfo: RTCXMediaType.IPlayInfo = {
  iotId: this.deviceInfo?.iotId,
  productKey: this.deviceInfo?.productKey,
  deviceName: this.deviceInfo?.deviceName,
  lensId: 0,
  streamType: 0,
  deviceType: 1 // 1：专属版设备
}

调用示例

// 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: 1 // 1：专属版设备
}
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。
