相机媒体服务器死了

Question

我有一个自定义视频录制应用程序已在多台设备上运行，但当我尝试在三星Galaxy Core Prime（SM-G361F）上运行时，相机会因以下错误消息而死机：

 W/IMediaDeathNotifier: media server died
 W/CameraBase: Camera service died!
 W/CameraBase: mediaserver's remote binder Camera object died
 W/AudioSystem: AudioPolicyService server died!
 W/AudioSystem: AudioFlinger server died!
 E/Camera: Error 100

这是相机的设置代码：

//@android.support.annotation.RequiresApi(api = Build.VERSION_CODES.M)
public boolean prepareVideoRecorderMP4( int rotation ){
    isImage = false;
    mLastRotation = rotation;
    setCamera( CameraHelper.getDefaultCameraInstance() );
    if( getCamera() == null )
    {
        return false;
    }
    // We need to make sure that our preview and recording video size are supported by the
    // camera. Query camera to find all the sizes and choose the optimal size given the
    // dimensions of our preview surface.
    Camera.Parameters parameters = getCamera().getParameters();
    int rotationCorrected = correctCameraRotation( rotation );
    parameters.setRotation( rotationCorrected );
    Camera.Size optimalSize = getCameraSize( parameters );
    parameters.setPreviewSize( optimalSize.width, optimalSize.height); 
    getCamera().setParameters(parameters);

}

我错过了什么吗？
