示例1: drawFrame
import android.view.SurfaceView; //导入方法依赖的package包/类
/**
* Draws a frame onto the SurfaceView and the encoder surface.
* <p>
* This will be called whenever we get a new preview frame from the camera. This runs
* on the UI thread, which ordinarily isn't a great idea -- you really want heavy work
* to be on a different thread -- but we're really just throwing a few things at the GPU.
* The upside is that we don't have to worry about managing state changes between threads.
* <p>
* If there was a pending frame available notification when we shut down, we might get
* here after onPause().
