Question

我正在尝试为Google Glass构建一个应用程序，该应用程序可以流式传输到服务器并让客户端通过Web浏览器查看流。到目前为止，似乎我需要通过RTSP到Wowza等媒体服务器，然后有一个托管一些视频播放器的Web服务器来查看RTMP流，但我没有太多运气。

使用libstreaming（https://github.com/fyhertz/libstreaming）我永远无法查看流。

我也有兴趣使用WebRTC做一些事情，这样我就可以制作类似于Hangouts的解决方案，但我不确定是否有任何库支持这个。

感谢任何帮助。

从1月份开始，libsreaming已经修复，可用于Glass。它的RTSP视频可以在VLC播放器或插件中轻松查看。下面的代码不包括自动生成的存根。

public class MainActivity extends Activity implements SurfaceHolder.Callback, Session.Callback {

private int mRtspPort = -1;

private ServiceConnection mRtspServerConnection = new ServiceConnection() {

    private static final int RTSP_PORT = 1234;

    @Override
    public void onServiceConnected(ComponentName className, IBinder binder) {
        RtspServer s = ((RtspServer.LocalBinder) binder).getService();
        s.setPort(RTSP_PORT);
        mRtspPort = s.getPort();
    }
  };

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
    setContentView(R.layout.activity_main);

    // Configures the SessionBuilder
    SessionBuilder.getInstance()
            .setSurfaceView((SurfaceView) findViewById(R.id.surface))
            .setCallback(this)
            .setPreviewOrientation(90)
            .setContext(getApplicationContext())
            .setAudioEncoder(SessionBuilder.AUDIO_NONE)
            .setVideoEncoder(SessionBuilder.VIDEO_H264)
            .setVideoQuality(new VideoQuality(320, 240, 20, 500000));

    // Starts the RTSP server
    bindService(new Intent(this, RtspServer.class), mRtspServerConnection, Context.BIND_AUTO_CREATE);
}

@Override
public void onResume() {
    super.onResume();
    mResumed = true;
    displayConnectString();
    SessionBuilder.getInstance().getSurfaceView().setAspectRatioMode(SurfaceView.ASPECT_RATIO_PREVIEW);
    SessionBuilder.getInstance().getSurfaceView().getHolder().addCallback(this);
}

private void displayConnectString() {
    WifiManager wifiMgr = (WifiManager) getSystemService(WIFI_SERVICE);
    WifiInfo wifiInfo = wifiMgr.getConnectionInfo();
    int ip = wifiInfo.getIpAddress();
    String ipAddress = Formatter.formatIpAddress(ip);
    ((TextView) findViewById(R.id.connectInfo)).setText("rtsp://" + ipAddress + ":" + mRtspPort);
}

@Override
public void onDestroy() {
    super.onDestroy();
    unbindService(mRtspServerConnection);
}

@Override
public void onSessionStarted() {
    ((TextView) findViewById(R.id.connectInfo)).setText("");
}

@Override
public void onSessionStopped() {
    displayConnectString();
}
}
