问题描述
我正在尝试使用Google Glass MIC录制音频,但我不断收到 W/IMediaDeathNotifier:媒体服务器死机错误.有想法吗?
I'm trying to record audio using Google Glass MIC but I keep getting W/IMediaDeathNotifier﹕ media server died error. Thoughts?
它应该在第一次触摸时开始记录,而在第二次触摸时停止,但是第一次单击时会发生错误.
It should start recording on the first touch and stops on the second touch, but the error happens on the first click.
package com.google.android.glass.sample.charades;
import android.media.MediaRecorder;
import java.io.IOException;
import android.util.Log;
import android.os.Environment;
public class SlideshowActivity extends Activity {
private static final String LOG_TAG = "AudioRecordTest";
private MediaRecorder mRecorder = null;
private static String mFileName = Environment.getExternalStorageDirectory().getAbsolutePath() + "/audiorecordtest.3gp";
private boolean recording = false;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_slideshow);
mGestureDetector = new GestureDetector(this).setBaseListener(mBaseListener);
}
private void startRecording() {
mRecorder = new MediaRecorder();
mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mRecorder.setOutputFile(mFileName);
mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
Log.e(LOG_TAG, "File name: " + mFileName);
try {
mRecorder.prepare();
} catch (IOException e) {
Log.e(LOG_TAG, "prepare() failed");
}
mRecorder.start();
}
private void stopRecording() {
mRecorder.stop();
mRecorder.release();
mRecorder = null;
}
private void onRecord(boolean start) {
if (start) {
startRecording();
} else {
stopRecording();
}
}
}

我还对 AndroidManifest.xml 文件添加了以下权限:
I've also added the following permission on the AndroidManifest.xml file:
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAPTURE_AUDIO_OUTPUT" />
推荐答案
尝试调用setPreviewDisplay
,它在任何地方都没有显示,但是有人说预览用作存储视频文件的来源.
Try calling setPreviewDisplay
, it isn't noted anywhere but some people say the preview is used as source to store the video file.
