Android Recording Library ======================================= Android Recording library offers convenient tools for audio/video recording and playback. For audio it uses: * AudioRecord to capture and save audio signal from microphone * MediaPlayer with MediaController to play recorded audio * custom Visualizer (like bar chart) to represent audio signal on screen while recording and during playback For video it uses: * Camera and MediaRecorder to record a video of specified resolution * MediaPlayer with MediaController to play recorded video * custom SurfaceView with adjustable size to properly display Camera preview and recorded video (in portrait and landscape modes) Record audio: how to use ------------------------ 1. Setup VisualizerView ```xml ``` ```java visualizerView = (VisualizerView) findViewById(R.id.visualizerView); setupVisualizer(); ... private void setupVisualizer() { Paint paint = new Paint(); paint.setStrokeWidth(5f); //set bar width paint.setAntiAlias(true); paint.setColor(Color.argb(200, 227, 69, 53)); //set bar color BarGraphRenderer barGraphRendererBottom = new BarGraphRenderer(2, paint, false); visualizerView.addRenderer(barGraphRendererBottom); } ``` 2. Start recording thread ```java private void startRecording() { recordingThread = new AudioRecordingThread(fileName, new AudioRecordingHandler() { //pass file name where to store the recorded audio @Override public void onFftDataCapture(final byte[] bytes) { runOnUiThread(new Runnable() { public void run() { if (visualizerView != null) { visualizerView.updateVisualizerFFT(bytes); //update VisualizerView with new audio portion } } }); } @Override public void onRecordSuccess() {} @Override public void onRecordingError() {} @Override public void onRecordSaveError() {} }); recordingThread.start(); } ``` 3. When done, stop recording ```java private void stopRecording() { if (recordingThread != null) { recordingThread.stopRecording(); recordingThread = null; } } ``` Play audio: how to use ------------------------ 1. Setup VisualizerView 2. Setup AudioPlaybackManager. It will attach MediaPlayer to a VisualizerView ```java playbackManager = new AudioPlaybackManager(this, visualizerView, playbackHandler); playbackManager.setupPlayback(fileName); //pass file name of the recorded audio ``` 3. Use onscreen MediaController to play/pause/stop/rewind audio Record video: how to use ------------------------ 1. Setup custom SurfaceView (AdaptiveSurfaceView) ```xml ``` 2. Setup RecordingManager ```java videoView = (AdaptiveSurfaceView) findViewById(R.id.videoView); recordingManager = new VideoRecordingManager(videoView, recordingHandler); //pass reference to custom SurfaceView ``` 3. Choose desired video resolution and pass it to RecordingManager, it will adjust size of AdaptiveSurfaceView to properly display Camera output ```java recordingManager.setPreviewSize(videoSize); ``` 4. To start recording use ```java recordingManager.startRecording(fileName, videoSize) ``` 5. To stop recording use ```java recordingManager.stopRecording() ``` Play video: how to use ------------------------ 1. Setup custom SurfaceView (AdaptiveSurfaceView) 2. Setup VideoPlaybackManager. It will attach MediaPlayer to a VisualizerView ```java playbackManager = new VideoPlaybackManager(this, videoView, playbackHandler); playbackManager.setupPlayback(fileName); //pass file name of the recorded video ``` 3. Use onscreen MediaController to play/pause/stop/rewind video ==================================== For more details, please, see the demo project.
