Record Video using surface view android

I have to create an android app in which i am trying to record video and capture image using surface view. Up to now i am able to capture video but facing problem in record video. My code for video recording is –

onCreate(){
      ..
     surfaceHolder = surfaceView.getHolder();
     surfaceHolder.addCallback(this);
     surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
     startRecording();
     .
     .
}


protected void startRecording() throws IOException
    {
        if(mCamera==null)
            mCamera = Camera.open();

         String filename;
         String path;

         path= Environment.getExternalStorageDirectory().getAbsolutePath().toString();

         Date date=new Date();
         filename="/rec"+date.toString().replace(" ", "_").replace(":", "_")+".mp4";

         File file=new File(path,filename);

        mrec = new MediaRecorder(); 

        mCamera.lock();
        mCamera.unlock();


        mrec.setCamera(mCamera);    
        mrec.setVideoSource(MediaRecorder.VideoSource.CAMERA);
        mrec.setAudioSource(MediaRecorder.AudioSource.MIC);     
        mrec.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
        mrec.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
        mrec.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
        mrec.setPreviewDisplay(surfaceHolder.getSurface());
        mrec.setOutputFile(path+filename);
        mrec.setMaxDuration(10000); 
  }
       @Override
    public void surfaceChanged(SurfaceHolder holder, int format, int width,int                height) {      

        Camera.Parameters parameters = mCamera.getParameters();      
        parameters.setPreviewSize(width, height);     
        try {
            mCamera.setPreviewDisplay(surfaceHolder);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        mCamera.setParameters(parameters);       
        mCamera.startPreview(); 

    }

but app force close when onSurfaceChange method code is called at line – mCamera.setPreviewDisplay(surfaceHolder); with exception java.lang.RuntimeException: setParameters failed

so how can i manage it so i can start video recording. Thanks in advance.

Answers

You can get a list of available preview sizes by calling getSupportedPreviewSizes in the Camera.Parameters object returned by Camera.getParameters. Check here

Add these below code inside surfaceChanged method

Camera.Parameters parameters = camera.getParameters();  
   List<Camera.Size> sizes = parameters.getSupportedPreviewSizes();  
   Camera.Size cs = sizes.get(0);  // You need to choose the most appropriate previewSize for your app. So select one from the list
   parameters.setPreviewSize(cs.width, cs.height);  
   camera.setParameters(parameters);
   camera.startPreview();

EDIT Change your surfaceChanged method like below and check

public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) {
        // If your preview can change or rotate, take care of those events here.
        // Make sure to stop the preview before resizing or reformatting it.
        Log.d("Function", "surfaceChanged");
        if (mHolder.getSurface() == null){
          // preview surface does not exist
          return;
        }

        // stop preview before making changes
        try {
            mCamera.stopPreview();
        } catch (Exception e){
          // ignore: tried to stop a non-existent preview
        }

        // set preview size and make any resize, rotate or
        // reformatting changes here


        // start preview with new settings
        try {
            mCamera.setPreviewDisplay(mHolder);
            mCamera.startPreview();

        } catch (Exception e){
            Log.d(TAG, "Error starting camera preview: " + e.getMessage());
        }
    }

Create a File for saving an image or video

private static File getOutputMediaFile(int type){
    // To be safe, you should check that the SDCard is mounted
    // using Environment.getExternalStorageState() before doing this.

    File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(
              Environment.DIRECTORY_PICTURES), "MyCameraApp");
    // This location works best if you want the created images to be shared
    // between applications and persist after your app has been uninstalled.

    // Create the storage directory if it does not exist
    if (! mediaStorageDir.exists()){
        if (! mediaStorageDir.mkdirs()){
            Log.d("MyCameraApp", "failed to create directory");
            return null;
        }
    }

    // Create a media file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    File mediaFile;
    if (type == MEDIA_TYPE_IMAGE){
        mediaFile = new File(mediaStorageDir.getPath() + File.separator +
        "IMG_"+ timeStamp + ".jpg");
    } else if(type == MEDIA_TYPE_VIDEO) {
        mediaFile = new File(mediaStorageDir.getPath() + File.separator +
        "VID_"+ timeStamp + ".mp4");
    } else {
        return null;
    }

    return mediaFile;
}
