获取surface

java部分：

surfaceview控件设置到界面中显示

surfaceview定义一个类来实现

package com.example.hello;
import android.content.context;
import android.opengl.glsurfaceview;
import android.util.attributeset;
import android.view.surfaceholder;
import javax.microedition.khronos.egl.eglconfig;
import javax.microedition.khronos.opengles.gl10;
public class xpaly extends glsurfaceview implements runnable, surfaceholder.callback {
    public xpaly(context context , attributeset attrs) {
        super(context);
    }
    @override
    public void run() {
      open("/sdcard/pictures/rc.mp4",getholder().getsurface());
    }
    @override
    public void surfacecreated(surfaceholder var1)
    {
    }
    @override
    public void surfacechanged(surfaceholder var1, int var2, int var3, int var4)
    {
      new thread(this).start();
    }
    @override
    public void surfacedestroyed(surfaceholder var1)
    {
    }
    public native void open(string url_,object surface);
}

实现surfaceview callback

需要android的库和头文件

#include 
#include 

c 部分

    //显示窗口初始化
    anativewindow *nwin = anativewindow_fromsurface(env,surface);
    int outwidth=vc->width;
    int outheight=vc->height;
    //设置native window的buffer大小，可自动拉伸
    anativewindow_setbuffersgeometry(nwin,outwidth,outheight,window_format_rgba_8888);
    anativewindow_buffer wbuf;

     //锁定窗口,取出空间
     anativewindow_lock(nwin,&wbuf,0);
     //取缓冲区地址
     uint8_t *dst = (uint8_t*)wbuf.bits;
     //数据拷贝到缓冲区中
     memcpy(dst,rgb,outwidth*outheight*4);
     //解锁窗口空间
     anativewindow_unlockandpost(nwin);
