Using CameraSource class instead of SurfaceHolder.Callback

0 down vote favorite

In my android application I have to use camera to scan some documents. Also I need to implement Google Mobile Vision (OCR) function to get the text from the doc. Specifically, I need that OCR in scanning activity because I need to identify the document type by reading the header.

I have tried capturing document edges using OpenCV and it was success. I have few clarifications in this stage for further development.

I have came across 2 ways to use camera, CameraSource and SurfaceHolder.Callback. What are the differences and drwabacks between those two?
Can I use CameraSource with OpenCV to overlay the edges realtime?
