【中文标题】设置 mMediaRecorder.setProfile 时出现 IllegalStateException

【英文标题】：IllegalStateException when set the mMediaRecorder.setProfile

【问题描述】：

我尝试设置

mMediaRecorder.setProfile((CamcorderProfile.get(CamcorderProfile.QUALITY_QVGA)));

当我启动相机服务时，我在日志中看到此错误：

    E/MediaRecorder: setOutputFormat called in an invalid state: 4

如果我删除了视频录制开始但质量低的代码

 mServiceCamera.unlock();
        mMediaRecorder = new MediaRecorder();
        mMediaRecorder.setCamera(mServiceCamera);
        mMediaRecorder.setAudiosource(MediaRecorder.AudioSource.CAMCORDER);
        mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
        mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
        mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
        mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);
        selectFolder(MainActivity.isHideFolder);
        mMediaRecorder.setPreviewDisplay(mSurfaceHolder.getSurface());
        mMediaRecorder.setOrientationHint(CameraUtil.computePictureRotation());
        mMediaRecorder.setProfile((CamcorderProfile.get(CamcorderProfile.QUALITY_QVGA)));
        mMediaRecorder.prepare();
        mMediaRecorder.start();

更新：

 public boolean startRecording() 
    try 
        Toast.makeText(getBaseContext(), "Recording Started", Toast.LENGTH_SHORT).show();

        if (!MainActivity.currentCameraId) 
            mServiceCamera = Camera.open(0);//CAMERA_FACING_BACK
            Log.d(TAG, "CAMERA_FACING_BACK");
         else 
            mServiceCamera = Camera.open(1);//CAMERA_FACING_FRONT
            Log.d(TAG, "CAMERA_FACING_FRONT");
        


        CamcorderProfile profile = CamcorderProfile.get(getqualityvideo(MainActivity.quality));
        mServiceCamera.unlock();
        mMediaRecorder = new MediaRecorder();
        mMediaRecorder.setCamera(mServiceCamera);
        mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
        mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
        mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
        int width = profile.videoFrameWidth;
        int height = profile.videoFrameHeight;
        mMediaRecorder.setVideoSize(width, height);
        mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);
        mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
        selectFolder(MainActivity.isHideFolder);//папка с видео

        mMediaRecorder.setOrientationHint(CameraUtil.computePictureRotation());

        mMediaRecorder.prepare();
        mMediaRecorder.start();

        mRecordingStatus = true;

        return true;
     catch (IllegalStateException e) 
        Log.e(TAG, e.getMessage() + " ошибка IllegalStateException");

        return false;
     catch (IOException e) 
        Log.e(TAG, e.getMessage() + " ошибка IOException");

        return false;
     catch (NullPointerException e) 
        Log.e(TAG, e.getMessage() + " ошибка NullPointerException");

        return false;

     catch (Exception e) 

        Log.e(TAG, e.getMessage() + " ошибка Exception");

        return false;
    

在日志中开始记录后我看到了这个：

【参考方案1】：

你会添加访问相机的权限吗？请检查一下。请参阅以下链接。 link link

【讨论】：

@upwardunkaind，对不起。我不认为你喜欢你所说的方式。有时，我们可能会错过一些小事。再次抱歉。

【参考方案2】：

您需要删除以下内容，因为通过将配置文件设置为 mediarecorder 也会这样做

mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);
mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);

删除下面两行也会做同样的事情

mMediaRecorder.setProfile((CamcorderProfile.get(CamcorderProfile.QUALITY_QVGA)));

或者，如果没有使用 setProfile 设置媒体记录器参数，则保持以下顺序并尝试

CamcorderProfile profile =CamcorderProfile.get(CamcorderProfile.QUALITY_QVGA);

mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mMediaRecorder.setVideoSize(640,480); /// video size make dynamic based on the requirement or view size
mMediaRecorder.setVideoFrameRate(profile.videoFrameRate); /// from profile
mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);

如果有任何事情请告诉我。
