android camera2 api - 如何將公司徽標添加到錄製的視頻文件

Hy everyone。我想在我錄製的視頻的角落添加一個小徽標。我試圖將imageView直接添加到錄製表面，但它不是解決方案。android camera2 api - 如何將公司徽標添加到錄製的視頻文件

我想我將不得不創建另一個表面並將它們合併在一起，但我找不到任何教程或代碼示例這樣的事情。

我找到了添加前景繪製選項的選項，但它並未在預覽表面上顯示徽標。這是代碼：

private void startRecording(){ 
    try { 
     setupMediaRecorder(); 
     mTextureView.setForeground(getDrawable(R.drawable.toolbarlogo)); 
     SurfaceTexture surfaceTexture = mTextureView.getSurfaceTexture(); 
     surfaceTexture.setDefaultBufferSize(mPreviewSize.getWidth(),mPreviewSize.getHeight()); 

     Surface previewSurfice = new Surface(surfaceTexture); 
     Surface recordSurface = mMediaRecorder.getSurface(); 

     mPreviewCaptureRequestBuilder = mCameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_RECORD); 
     mPreviewCaptureRequestBuilder.addTarget(previewSurfice); 
     mPreviewCaptureRequestBuilder.addTarget(recordSurface); 

     mCameraDevice.createCaptureSession(Arrays.asList(previewSurfice, recordSurface), new CameraCaptureSession.StateCallback() { 
      @Override 
      public void onConfigured(@NonNull CameraCaptureSession session) { 
       try { 
        session.setRepeatingRequest(
          mPreviewCaptureRequestBuilder.build(),null,null 
        ); 
       } catch (CameraAccessException e) { 
        e.printStackTrace(); 
       } 
      } 

      @Override 
      public void onConfigureFailed(@NonNull CameraCaptureSession session) { 

      } 
     },null); 



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

請大家幫忙。謝謝
