RecordVideo：java.lang.RuntimeException：啟動失敗

Question

我對使用android 4.1.2的nexus s進行視頻重新編碼存在問題。

 private static final String OUTPUT_FILE="/storage/sdcard0/uatestvideo1.mp4";

Android清單：

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.RECORD_AUDIO"/>
<uses-permission android:name="android.permission.RECORD_VIDEO"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.STORAGE" />
<uses-feature android:name="android.hardware.camra"/>

onCreate：在oncreate我有：...

final SurfaceHolder holder =    videoView.getHolder();
holder.addCallback(this);
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

...

private void beginRecording(SurfaceHolder holder) throws Exception{

        if(recorder!=null){
            recorder.stop();
            recorder.release();
            recorder=null;
        }
        File outFile = new File(OUTPUT_FILE);
        if(outFile.exists()){
            outFile.delete();
        }

        try{
            recorder = new MediaRecorder();
            recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
            recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
            recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
            recorder.setVideoSize(320, 240);
            recorder.setVideoFrameRate(15);
            recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
            recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
            recorder.setMaxDuration(200000);
            recorder.setPreviewDisplay(holder.getSurface());
            recorder.setOutputFile(OUTPUT_FILE);
            recorder.prepare();
                recorder.start();
        }catch(Exception e){
            Log.e(TAG, e.toString());
            e.printStackTrace();
        }

    }


}

Answer 1

-19是NO_INIT的錯誤。 這意味着您的recorder未正確初始化。
