Question

我目前正在开展一个项目。我现在可以从Ip相机获取视频，我想录制在surfaceView中显示的视频。我不知道如何做到这一点。这是我写的视频预览代码。任何帮助将不胜感激。

public class Camera_Fragment1 extends Fragment implements IVideoPlayer, View.OnTouchListener, View.OnClickListener {
private RotateCam Task = new RotateCam();
private StopCam Task1 = new StopCam();
private ConnectionAdapter adapter = new ConnectionAdapter();
private TextView tv;
private Button Cam1_up, Cam1_dowm, Cam1_right, Cam1_left, Cam_Record;
private String GotUrl;
private SurfaceView Cam1View;
private String Cam1_VideoUrl = "http://192.168.0.4:81/videostream.cgi?user=admin&password=admin";
private SurfaceHolder Cam1_Holder;
private Surface Cam1_surface = null;
private LibVLC Cam1_libVLC;
private Boolean recording;
private int mVideoHeight;
private int mVideoWidth;
private int mVideoVisibleHeight;
private int mVideoVisibleWidth;
private int mSarNum;
private int mSarDen;

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.cam1, container, false);
    Cam1View = (SurfaceView) view.findViewById(R.id.Cam1_CamVIew);

    tv = (TextView) view.findViewById(R.id.textView2);

    Cam1_up = (Button) view.findViewById(R.id.Cam_up);
    Cam1_dowm = (Button) view.findViewById(R.id.Cam_down);

    }
}

private class RotateCam extends AsyncTask<String, String, String> {
    @Override
    protected String doInBackground(String... params) {
        adapter.CamRotation(params[0]);
        return null;
    }
}

private class StopCam extends AsyncTask<String, String, String> {
    @Override
    protected String doInBackground(String... params) {
        adapter.StopRotation();
        return null;
    }
}}

我已经使用Lib-Vlc预览视频到surfaceview，因为android不支持基于tcp的视频传输。
