Linphone SDK - 如何打开外放

Question

我正在通过 Linphone SDK 构建一个视频聊天应用程序。

有一个问题，当某人"receives"视频通话时，扬声器默认关闭，因此用户需要使用phone扬声器，phone 呼叫，而不是外放。不过同时，来电者的喇叭默认是开着的。

LinphoneManager.getInstance().routeAudioToSpeaker();

我以为这是林phone打开扬声器的代码，但实际上不是。

用户接听视频电话时默认开启外放如何？

Answer 1

LinphoneCore 有两个方便的方法：

enableSpeaker(boolean)

muteMic(boolean)

只需在内部创建辅助函数 LinphoneManager:

public void enableVoice() {
    getLc().muteMic(false);
    getLc().enableSpeaker(true);
}

public void disableVoice() {
    getLc().muteMic(true);
    getLc().enableSpeaker(false);
}

如果您无权访问 LinphoneManager，则上述函数应调用：

LinphoneManager.getLc().{method_call};

Answer 2

private AudioManager mAudioManager;

...

public LinphoneMiniManager(Context c) {
        mContext = c;
        mAudioManager = ((AudioManager) c.getSystemService(Context.AUDIO_SERVICE));

        mAudioManager.setSpeakerphoneOn(true);
...

Answer 3

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    
    ....
    
    btnSpeaker.setOnClickListener {
        mIsSpeakerEnabled = !mIsSpeakerEnabled
        it.isSelected = mIsSpeakerEnabled
        toggleSpeaker()
    }

    ....
  
}



private fun toggleSpeaker() {

        val currentAudioDevice = core.currentCall?.outputAudioDevice
        val speakerEnabled = currentAudioDevice?.type == AudioDevice.Type.Speaker

        for (audioDevice in core.audioDevices) {
            if (speakerEnabled && audioDevice.type == AudioDevice.Type.Earpiece) {
                core.currentCall?.outputAudioDevice = audioDevice
                return
            } else if (!speakerEnabled && audioDevice.type == AudioDevice.Type.Speaker) {
                core.currentCall?.outputAudioDevice = audioDevice
                return
            }/* If we wanted to route the audio to a bluetooth headset
            else if (audioDevice.type == AudioDevice.Type.Bluetooth) {
                core.currentCall?.outputAudioDevice = audioDevice
            }*/
        }
    }
