【问题描述】：

我已经看到了很多关于如何使用 Surfaceview 将视频从 android 摄像头实时流式传输到 rtmp 服务器的示例。一个在这里：https://github.com/begeekmyfriend/yasea

但是是否可以使用纹理视图将视频从相机流式传输到 rtmp？如果是，我们怎么办？

Textureview mTextureView;

// inside oncreate

mTextureView = (TextureView) findViewById(R.id.texture_view);
mTextureView.setSurfaceTextureListener(AircraftControlActivity.this);



// Outside OnCreate
@Override
public void onSurfaceTextureAvailable(final SurfaceTexture surface, final int width, final int height) 



@Override
public void onSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height) 



@Override
public boolean onSurfaceTextureDestroyed(SurfaceTexture surface) 




@Override
public void onSurfaceTextureUpdated(final SurfaceTexture surface) 

接下来要做什么？

【参考方案1】：

看看Texture View

public class MainActivity extends AppCompatActivity implements TextureView.SurfaceTextureListener


    Camera camera;
    TextureView textureView;
    ImageButton button ;  //ignore this one

    @Override
    protected void onCreate(Bundle savedInstanceState)
    
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        textureView = (TextureView) findViewById(R.id.textureView);
        button = (ImageButton)findViewById(R.id.imageButton);

        textureView.setSurfaceTextureListener(this);

    

    @Override
    public void onSurfaceTextureAvailable(SurfaceTexture surface, int width, int height)
    
        camera = Camera.open();
        try
        
            camera.setPreviewTexture(surface);
            camera.startPreview();
        
        catch (IOException ioe)
        
            // Something bad happened
        
    

    @Override
    public void onSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height)
    
        // Ignored, Camera does all the work for us
    

    @Override
    public boolean onSurfaceTextureDestroyed(SurfaceTexture surface)
    
        camera.stopPreview();
        camera.release();
        return true;
    

    @Override
    public void onSurfaceTextureUpdated(SurfaceTexture surface)
    
        // Invoked every time there's a new Camera preview frame
