从 Android 上的 Axis 摄像头获取 rtsp 流

Question

我正在尝试将来自 Axis 摄像头的 rtsp 流显示到媒体播放器对象中，代码如下：

public class Rtsp extends Activity {

String PATH_TO_STREAM = "rtsp://192.168.131.21/mpeg4/1/media.3gp";

private VideoView video;
private MediaController ctlr;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    video=(VideoView)findViewById(R.id.video);
    ctlr=new MediaController(this);
    ctlr.setAnchorView(video);

    Uri videoUri = Uri.parse(PATH_TO_STREAM);
    video.setMediaController(ctlr);
    video.setVideoURI(videoUri);
    video.start();
}}

我可以使用 VLC 正确进行流式传输，但使用 Android 时出现此错误：

02-10 11:58:07.071: ERROR/PlayerDriver(31): Command PLAYER_PREPARE completed with an error or info PVMFErrResourceConfiguration

02-10 11:58:12.902: DEBUG/dalvikvm(106): GC freed 2635 objects / 150552 bytes in 314ms

有任何提示吗？谢谢

在 video.start(); 之前调用 video.requestFocus();。我想这会让你的代码运行。
