我现在正在使用 UVC 摄像头，并将视频和音频从 UVC 摄像头发送到 Android 手机
当我尝试用 记录时AudioRecord，奇怪的值进来了，我很困惑。
有没有办法设置AudioRecord使用 UVC 相机的麦克风？
音频在 Play Store 上的其他应用程序中运行良好，因此必须有某种方法可以使其正常工作。
int bufferSize = AudioRecord.getMinBufferSize(sampleRate, recorder_channels, RECORDER_AUDIO_ENCODING) ;
// bufferSize *= 2;
if(audioMode == AudioManager.MODE_NORMAL)
audioRecord = new AudioRecord(MediaRecorder.AudioSource.MIC, sampleRate, recorder_channels, RECORDER_AUDIO_ENCODING, bufferSize);
else if(audioMode == AudioManager.MODE_IN_COMMUNICATION)
audioRecord = new AudioRecord(MediaRecorder.AudioSource.VOICE_COMMUNICATION, sampleRate, recorder_channels, RECORDER_AUDIO_ENCODING, bufferSize);
if(audioRecord.getState() == AudioRecord.STATE_INITIALIZED) {
audioRecord.startRecording();
}
short[] sData = new short[bufferSize/2];
while ( isRun)
{
int bufferReadResult = audioRecord.read(sData, 0, bufferSize/2);
byte[] buffer = short2byte(sData);
if(mute)
Arrays.fill(buffer, (byte) 0);
pcmQueue.add(buffer);
}
if(audioRecord != null)
{
if(audioRecord.getState() != AudioRecord.STATE_INITIALIZED) {
audioRecord.stop();
audioRecord.release();
}
}
