Question

如果音频持续时间超过1分钟，我试图将记录的音频文件分成较小的块，每个较小的块分别为1分钟，并在Android中将它们视为单独的音频文件。

我通过以下操作录制音频：-

MediaRecorder mAudioRecorder = new MediaRecorder();
    mAudioRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    mAudioRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
    mAudioRecorder.setAudioEncoder(MediaRecorder.OutputFormat.AMR_NB);
    mAudioRecorder.setOutputFile(outputFile);
    startRecording();

当我录制上述音频时，它会被正确录制并播放。现在要剪辑此音频，我正在使用[this] [1]库。

    CheapSoundFile cheapSoundFile = CheapSoundFile.create(in_file_path,listner);

    int mSampleRate = cheapSoundFile.getSampleRate();

    int mSamplesPerFrame = cheapSoundFile.getSamplesPerFrame();

    int startFrame = Utilities.secondsToFrames(5.0,mSampleRate, mSamplesPerFrame);

    int endFrame = Utilities.secondsToFrames(30.0, mSampleRate,mSamplesPerFrame);

String outputFileDirectory = Environment.getExternalStorageDirectory().getAbsolutePath() + this.getString(R.string.recording_folder);

                try
                {
                    File dir = new File(outputFileDirectory);
                    if (!dir.exists())
                    {
                        dir.mkdirs();
                    }
                    mFileNumber++;
                    outputFile = outputFileDirectory + "Clip_" + String.valueOf(mFileNumber) + this.getString(R.string.recording_mp3);
                }
                catch (Exception e)
                {
                    e.printStackTrace();
                }
    cheapSoundFile.WriteFile(outputFile , startFrame, endFrame-startFrame);

    final CheapSoundFile.ProgressListener listener = new CheapSoundFile.ProgressListener() {
        public boolean reportProgress(double frac) {

        return true; 
        }
    };

然后，我将剪切后的文件播放为：-

MediaPlayer mediaPlayer = new MediaPlayer();
                try
                {
                    if (mediaPlayer != null)
                    {
                        mediaPlayer.setDataSource(outputFile);
                        mediaPlayer.prepare();
                    }
                    mediaPlayer.start();

                }
                catch (Exception e)
                {
                    e.printStackTrace();
                }

但是，播放剪辑的音频时出现异常：-

setDataSourceFD failed.: status=0x80000000

对于解决此问题的任何帮助，我们深表感谢。谢谢。

setDataSourceFD失败。：播放音频时状态= 0x80000000
