Android Player¶

Example of player for Android¶

This player can be used to play any type of stream on Web Call Server

RTSP
WebRTC
RTMP

On the screenshot below an RTSP stream is being playing.

In the input fields

192.168.2.104 in the URL is the address of the WCS server
stream name is entered in to the Play Stream field (RTSP URL in this case)

Analyzing the example code¶

To analyze the code, let's take class PlayerActivity.java of the player example, which can be downloaded with corresponding build 1.0.1.38.

1. Initialization of the API¶

Flashphoner.init() code

For initialization, Сontext object is passed to the init() method.

Flashphoner.init(this);

2. Session creation¶

Flashphoner.createSession() code

SessionOptions object with the following parameters is passed to createSession() metod

URL of WCS server
SurfaceViewRenderer remoteRenderer, which will be used to play video stream

SessionOptions sessionOptions = new SessionOptions(mWcsUrlView.getText().toString());
sessionOptions.setRemoteRenderer(remoteRender);

/**
  * Session for connection to WCS server is created with method createSession().
  */
session = Flashphoner.createSession(sessionOptions);

3. Connection to the server¶

Session.connect() code

session.connect(new Connection());

4. Receiving the event confirming successful connection¶

Session.onConnected() code

@Override
public void onConnected(final Connection connection) {
    runOnUiThread(new Runnable() {
        @Override
        public void run() {
            mStartButton.setText(R.string.action_stop);
            mStartButton.setTag(R.string.action_stop);
            mStartButton.setEnabled(true);
            mStatusView.setText(connection.getStatus());
            ...
        }
    });
}

5. Playback of video stream¶

Session.createStream(), Stream.play() code

StreamOptions object with name of the stream is passed to the createStream() method

StreamOptions streamOptions = new StreamOptions(mPlayStreamView.getText().toString());

/**
  * Stream is created with method Session.createStream().
  */
playStream = session.createStream(streamOptions);

/**
  * Callback function for stream status change is added to display the status.
  */
playStream.on(new StreamStatusEvent() {
    @Override
    public void onStreamStatus(final Stream stream, final StreamStatus streamStatus) {
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                if (!StreamStatus.PLAYING.equals(streamStatus)) {
                    Log.e(TAG, "Can not play stream " + stream.getName() + " " + streamStatus);
                } else if (StreamStatus.NOT_ENOUGH_BANDWIDTH.equals(streamStatus)) {
                    Log.w(TAG, "Not enough bandwidth stream " + stream.getName() + ", consider using lower video resolution or bitrate. " +
                          "Bandwidth " + (Math.round(stream.getNetworkBandwidth() / 1000)) + " " +
                          "bitrate " + (Math.round(stream.getRemoteBitrate() / 1000)));
                } else {
                    mStatusView.setText(streamStatus.toString());
                }
            }
        });
    }
});

/**
  * Method Stream.play() is called to start playback of the stream.
  */
playStream.play();

6. Session disconnection¶

Session.disconnect() code

session.disconnect();

7. Receiving the event confirming successful disconnection¶

Session.onDisconnection() code

@Override
public void onDisconnection(final Connection connection) {
    runOnUiThread(new Runnable() {
        @Override
        public void run() {
            mStartButton.setText(R.string.action_start);
            mStartButton.setTag(R.string.action_start);
            mStartButton.setEnabled(true);
            mStatusView.setText(connection.getStatus());
        }
    });
}
