- 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)
Work with code of the example
To analyze the code, let's take class PlayerActivity.java of of the player example version with hash 4ed4c6d77, which can be downloaded with corresponding build 1.0.1.338.
1. Initialization of the API. line 61

For initialization, object Сontext is passed to the init() method.
2. Connection to server.
Session for connection to server is created when Start button is clicked. line 89
Code Block | ||||
---|---|---|---|---|
| ||||
session = Flashphoner.createSessioninit(sessionOptionsthis); |
Session is created with method 2. Session creation.
Flashphoner.createSession(), to which object SessionOptions (line 83) code
Object SessionOptions with the following parameters is passed to createSession() metod()
- URL of WCS server
- SurfaceViewRenderer, which will be used to play video stream
Callback functions for session events are added (line 94)
...
Code Block | ||||
---|---|---|---|---|
| ||||
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
Code Block | ||||
---|---|---|---|---|
| ||||
session.onconnect(new SessionEvent() { Connection()); |
4. Receiving the event confirming successful connection
session.onConnected() code
Code Block | ||||
---|---|---|---|---|
| ||||
@Override public void onConnected(final Connection connection) { runOnUiThread(new Runnable() { .....@Override } public void onDisconnectionrun(final Connection connection) { mStartButton.setText(R.string.action_stop); mStartButton.setTag(R.string.action_stop); } }); |
Method Session.connect() is called to establish connection with WCS server. line 176
Code Block | ||||
---|---|---|---|---|
| ||||
session.connect(new Connection()); |
...
mStartButton.setEnabled(true);
mStatusView.setText(connection.getStatus());
...
}
});
} |
5. Playback of video stream.
After establishing connection to the server, new video stream is created with method Session.createStream(). line 119, Stream.play() code
Object StreamOptions (line 114) with name of the stream is passed to the createStream() method.
Code Block | ||||
---|---|---|---|---|
| ||||
StreamOptions streamOptions = new StreamOptions(mPlayStreamView.getText().toString());
/**
* Stream is created with method Session.createStream().
*/
playStream = session.createStream(streamOptions); |
Method Stream.play() is called to play the stream. line 142
Code Block | ||||
---|---|---|---|---|
| ||||
/** * 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. Sessino disconnection.
Session.disconnect() code
Code Block | ||||
---|---|---|---|---|
| ||||
playStreamsession.playdisconnect(); |
5. Disconnection. line 188
Method Session.disconnect() is called to close connection to the server.7. Receiving the event confirming successful disconnection
session.onDisconnection() code
Code Block | ||||
---|---|---|---|---|
| ||||
session.disconnect();@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()); } }); } |
