使用VideoView和MediaPlayer的Rtsp流媒体

Question

我想开发一款android应用程序，它将从本地服务器播放rtsp链接，但平板电脑屏幕变为空白。。。。什么也没显示我试过VideoView和MediaPlayer两个类。适用于扩展名为.3gp的youtube rtsp链接，但不适用于上述URL下面是我的代码

public class WifiManagerActivity extends Activity {
private WifiManager  customWifiManager;
private VideoView mu;
private String path;
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        wifiSettings();
    }
    private void wifiSettings() {
        mu  = (VideoView) findViewById(R.id.ttl);
        TextView notify = (TextView) findViewById(R.id.wifi_state);
        customWifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
                if(customWifiManager.isWifiEnabled()){
            Toast.makeText(this, "Your wifi is On now enjoy " +
                    "live streaming", Toast.LENGTH_SHORT).show();
            notify.setTextColor(Color.GREEN);
            showVideo();
        }else{
        Toast.makeText(this, "Turn your Wifi On", Toast.LENGTH_SHORT).show();
        customWifiManager.setWifiEnabled(true);
        //two second wait here
        showVideo();
        }
    }
    private void showVideo() {

        Authenticator.setDefault(new MyAuthenticater());
        String path = "rtsp://192.168.1.155:554/3g";
        mu.setVideoURI(Uri.parse(path));
        mu.setMediaController(new MediaController(this));
        mu.requestFocus();
        mu.start();
    }
}

Answer 1

有多种因素会影响流是否正确播放：

1. 检查您的流是否有效和可播放（例如使用VLC的单独实例）
2. 如果有效，请检查logcat是否存在与RTSP连接或视频流本身相关的任何错误/警告。查找标签，如：MediaPlayer、ARTSPConnection，MyHandler和ASessionDescription以及ACodec

这应该会让你开始。
