Пример Android-приложения с плеером и стримером
Данное приложение может использоваться для публикации WebRTC-видеопотока и воспроизведения любого из следующих типов потоков с Web Call Server:
...
Слева отображается видео с камеры, справа воспроизводится другой поток.
Работа с кодом примера
Для разбора кода возьмем класс StreamingMinActivity.java примера streaming-min, который доступен для скачивания в соответствующей сборке 1.0.1.38.

Flashphoner.init() код
Code Block | ||||
---|---|---|---|---|
| ||||
Flashphoner.init(this); |
При инициализации методу init() передается объект Сontext.
...
- URL WCS-сервера
- SurfaceViewRenderer localRenderer, который будет использоваться для отображения видео с камеры
- SurfaceViewRenderer remoteRenderer, который будет использоваться для отображения воспроизводимого потока
Code Block | ||||
---|---|---|---|---|
| ||||
sessionOptions = new SessionOptions(mWcsUrlView.getText().toString()); sessionOptions.setLocalRenderer(localRender); sessionOptions.setRemoteRenderer(remoteRender); /** * Uncomment this code to use your own RTCConfiguration. For example, you can use custom TURN server */ //List<PeerConnection.IceServer> iceServers = new ArrayList<>(); //iceServers.add(new PeerConnection.IceServer("turn:your.turn-server.com:443?transport=tcp","username","passw0rd")); //PeerConnection.RTCConfiguration customConfig = new PeerConnection.RTCConfiguration(iceServers); //sessionOptions.setMediaOptions(customConfig); /** * Session for connection to WCS server is created with method createSession(). */ session = Flashphoner.createSession(sessionOptions); |

Session.connect(). код
Code Block | ||||
---|---|---|---|---|

Code Block | ||||
---|---|---|---|---|
| ||||
mPublishButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View view) { if (mPublishButton.getTag() == null || Integer.valueOf(R.string.action_publish).equals(mPublishButton.getTag())) { ActivityCompat.requestPermissions(StreamingMinActivity.this, new String[]{Manifest.permission.RECORD_AUDIO, Manifest.permission.CAMERA}, PUBLISH_REQUEST_CODE); SharedPreferences sharedPref = StreamingMinActivity.this.getPreferences(Context.MODE_PRIVATE); SharedPreferences.Editor editor = sharedPref.edit(); editor.putString("publish_stream", mPublishStreamView.getText().toString()); editor.apply(); ... } else { mPublishButton.setEnabled(false); /** * Method Stream.stop() is called to unpublish the stream. */ publishStream.stop(); publishStream = null; } View currentFocus = getCurrentFocus(); if (currentFocus != null) { InputMethodManager inputManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE); inputManager.hideSoftInputFromWindow(currentFocus.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS); } } } ... } ... } }); |
6. Публикация потока после предоставления соответствующих прав

Code Block | ||||
---|---|---|---|---|
| ||||
case PUBLISH_REQUEST_CODE: { if (grantResults.length == 0 || grantResults[0] != PackageManager.PERMISSION_GRANTED || grantResults[1] != PackageManager.PERMISSION_GRANTED) { Log.i(TAG, "Permission has been denied by user"); } else { mPublishButton.setEnabled(false); /** * The options for the stream to publish are set. * The stream name is passed when StreamOptions object is created. */ StreamOptions streamOptions = new StreamOptions(mPublishStreamView.getText().toString()); /** * Uncomment this code to use case WebRTC-as-RTMP. Stream will be republished to your rtmpUrl */ //streamOptions.setRtmpUrl("rtmp://192.168.1.100:1935/live2"); /** * Stream is created with method Session.createStream(). */ publishStream = session.createStream(streamOptions); /** * Callback function for stream status change is added*/ to make appropriate changes in controls of thepublishStream interface= when publishing. */ publishStream.on(new StreamStatusEvent() { @Override public void onStreamStatus(final Stream stream, final StreamStatus streamStatus) { runOnUiThread(new Runnable() { @Override public void run() { if (StreamStatus.PUBLISHING.equals(streamStatus)) { mPublishButton.setText(R.string.action_unpublish); mPublishButton.setTag(R.string.action_unpublish); } else { mPublishButton.setText(R.string.action_publish); mPublishButton.setTag(R.string.action_publish); } mPublishButton.setEnabled(true); mPublishStatus.setText(streamStatus.toString()); } }); } }); /** session.createStream(streamOptions); ... /** * Method Stream.publish() is called to publish stream. */ publishStream.publish(); Log.i(TAG, "Permission has been granted by user"); } } |
7. Воспроизведение потока при нажатии Play

" + "Bandwidth " + (Math.round(stream.getNetworkBandwidth() / 1000)) + " " + "bitrate " + (Math.round(stream.getRemoteBitrate() / 1000))); } else { mPlayButton.setText(R.string.action_play); mPlayButton.setTag(R.string.action_play); } mPlayButton.setEnabled(true); mPlayStatus.setText(streamStatus.toString()); } }); } }); /** *playStream = session.createStream(streamOptions); ... /** * Method Stream.play() is called to start playback of the stream. */ playStream.play(); SharedPreferences sharedPref = StreamingMinActivity.this.getPreferences(Context.MODE_PRIVATE); SharedPreferences.Editor editor = sharedPref.edit(); editor.putString("play_stream", mPlayStreamView.getText().toString()); editor.apply(); ... } else { /** * Method Stream.stop() is called to stop playback of the stream. */ playStream.stop(); playStream = null; } View currentFocus = getCurrentFocus(); if (currentFocus != null) { InputMethodManager inputManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE); inputManager.hideSoftInputFromWindow(currentFocus.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS); } ... } ... } }); |
