Android WebRTC实施-体积非常小 [英] Android WebRTC implementaion - very low volume

问题描述

我已使用以下示例在我的应用程序中实现了视频会议的选项: https://github.com/androidthings/sample-videoRTC

I have implement an option of Video Conference on my application using the following example: https://github.com/androidthings/sample-videoRTC

基本上工作得很好，但是我有一个主要问题.即使我将最大音量放在设备上，声音的音量也非常低.

basically is is working very well but i have one major issue. the sreaming audio volume is very very low even when i put the maximum volume on my device.

我尝试检查是否有任何参数可以定义音频音量，但是在AudioBitRate(= 32)和AudioCodec =("OPUS")旁边找不到此类参数.

I have tried to check if there is any parameter that can define the audio volume but is was not able to find such parameters beside the AudioBitRate(=32) and the AudioCodec=("OPUS").

以下是用于创建peerConnection的参数:

These are the parameters that is am using for creating the peerConnection:

    peerConnectionParameters =
            new PeerConnectionClient.PeerConnectionParameters(true,
                    false,
                    false,
                    videoWidth,
                    videoHeight,
                    0,
                    Integer.parseInt(getString(R.string.pref_maxvideobitratevalue_default)),
                    getString(R.string.pref_videocodec_default),
                    true,
                    false,
                    Integer.parseInt(getString(R.string.pref_startaudiobitratevalue_default)),
                    getString(R.string.pref_audiocodec_default),
                    false,
                    false,
                    false,
                    false,
                    false,
                    false,
                    false,
                    false,
                    null);

有人知道如何提高音量吗?

Is anyone have some idea how can I improve the audio volume?

我尝试替换默认的音频编解码器，但结果是相同的低音量.

Ihave tried to replace the default Audio Codec but the result was the same low vloume.

推荐答案

经过多次检查和调查，我发现了问题所在.如果有人会遇到同样的问题，我会在这里回答.

After many check and investigation i have found the problem. i am answering it here if someone else will have the same problem.

我注意到声音不是传递给扬声器，而是传递给耳塞...所以我添加了下面的代码来打开扬声器，问题已经解决了！

i have notice that the voice is not routed to the speaker but to the ear cap...so i add the bellow code to turn on the speaker and the problem has solved !

    audioManager = (AudioManager) this.activity.getSystemService(Context.AUDIO_SERVICE);
    audioManager.setSpeakerphoneOn(true);
    audioManager.setMode(AudioManager.MODE_IN_COMMUNICATION);

要回答我将代码放在哪里的问题，实际上我已经添加了一个新图标，以使用户可以在耳机和扬声器之间切换.

To answer the question where i put the code, i have actually add a new icon to give the user to switch between headset and speaker.

这是完整的代码:

    toggleSpeakerHeadset.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (speakerOn) {
                setHeadsetOn();
            } else {
                setSpeakerOn();
            }
        }
    });

private void setSpeakerOn() {
    speakerOn = true;
    toggleSpeakerHeadset.setImageResource(R.drawable.headset);
    audioManager.setSpeakerphoneOn(true);
    audioManager.setMode(AudioManager.MODE_IN_COMMUNICATION);
}

private void setHeadsetOn() {
    speakerOn = false;
    toggleSpeakerHeadset.setImageResource(R.drawable.speaker);
    audioManager.setSpeakerphoneOn(false);
    audioManager.setMode(AudioManager.MODE_IN_COMMUNICATION);
}
