How can I record a video in my Android app?
Here is a simple video recording example using the MediaRecorder:
public class VideoCapture extends Activity implements OnClickListener, SurfaceHolder.Callback { MediaRecorder recorder; SurfaceHolder holder; boolean recording = false; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); recorder = new MediaRecorder(); initRecorder(); setContentView(R.layout.main); SurfaceView cameraView = (SurfaceView) findViewById(R.id.CameraView); holder = cameraView.getHolder(); holder.addCallback(this); holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); cameraView.setClickable(true); cameraView.setOnClickListener(this); } private void initRecorder() { recorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT); recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT); CamcorderProfile cpHigh = CamcorderProfile .get(CamcorderProfile.QUALITY_HIGH); recorder.setProfile(cpHigh); recorder.setOutputFile("/sdcard/videocapture_example.mp4"); recorder.setMaxDuration(50000); // 50 seconds recorder.setMaxFileSize(5000000); // Approximately 5 megabytes } private void prepareRecorder() { recorder.setPreviewDisplay(holder.getSurface()); try { recorder.prepare(); } catch (IllegalStateException e) { e.printStackTrace(); finish(); } catch (IOException e) { e.printStackTrace(); finish(); } } public void onClick(View v) { if (recording) { recorder.stop(); recording = false; // Let's initRecorder so we can record again initRecorder(); prepareRecorder(); } else { recording = true; recorder.start(); } } public void surfaceCreated(SurfaceHolder holder) { prepareRecorder(); } public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { } public void surfaceDestroyed(SurfaceHolder holder) { if (recording) { recorder.stop(); recording = false; } recorder.release(); finish(); }}It's from my book: Pro Android Media: Developing Graphics, Music, Video, and Rich Media Apps for Smartphones and Tablets
Also, do not forget to include these permissions in manifest:
<uses-permission android:name="android.permission.RECORD_AUDIO" /><uses-permission android:name="android.permission.CAMERA" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Here is another example which is working
public class EnregistrementVideoStackActivity extends Activity implements SurfaceHolder.Callback { private SurfaceHolder surfaceHolder; private SurfaceView surfaceView; public MediaRecorder mrec = new MediaRecorder(); private Button startRecording = null; File video; private Camera mCamera; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.camera_surface); Log.i(null , "Video starting"); startRecording = (Button)findViewById(R.id.buttonstart); mCamera = Camera.open(); surfaceView = (SurfaceView) findViewById(R.id.surface_camera); surfaceHolder = surfaceView.getHolder(); surfaceHolder.addCallback(this); surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); } @Override public boolean onCreateOptionsMenu(Menu menu) { menu.add(0, 0, 0, "StartRecording"); menu.add(0, 1, 0, "StopRecording"); return super.onCreateOptionsMenu(menu); } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case 0: try { startRecording(); } catch (Exception e) { String message = e.getMessage(); Log.i(null, "Problem Start"+message); mrec.release(); } break; case 1: //GoToAllNotes mrec.stop(); mrec.release(); mrec = null; break; default: break; } return super.onOptionsItemSelected(item); } protected void startRecording() throws IOException { mrec = new MediaRecorder(); // Works well mCamera.unlock(); mrec.setCamera(mCamera); mrec.setPreviewDisplay(surfaceHolder.getSurface()); mrec.setVideoSource(MediaRecorder.VideoSource.CAMERA); mrec.setAudioSource(MediaRecorder.AudioSource.MIC); mrec.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH)); mrec.setPreviewDisplay(surfaceHolder.getSurface()); mrec.setOutputFile("/sdcard/zzzz.3gp"); mrec.prepare(); mrec.start(); } protected void stopRecording() { mrec.stop(); mrec.release(); mCamera.release(); } private void releaseMediaRecorder(){ if (mrec != null) { mrec.reset(); // clear recorder configuration mrec.release(); // release the recorder object mrec = null; mCamera.lock(); // lock camera for later use } } private void releaseCamera(){ if (mCamera != null){ mCamera.release(); // release the camera for other applications mCamera = null; } } @Override public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { } @Override public void surfaceCreated(SurfaceHolder holder) { if (mCamera != null){ Parameters params = mCamera.getParameters(); mCamera.setParameters(params); } else { Toast.makeText(getApplicationContext(), "Camera not available!", Toast.LENGTH_LONG).show(); finish(); } } @Override public void surfaceDestroyed(SurfaceHolder holder) { mCamera.stopPreview(); mCamera.release(); }}camera_surface.xml
<?xml version="1.0" encoding="UTF-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical" ><SurfaceView android:id="@+id/surface_camera" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_weight="1" /><Button android:id="@+id/buttonstart" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/record_start" /></RelativeLayout>And of course include these permission in manifest:
<uses-permission android:name="android.permission.RECORD_AUDIO" /><uses-permission android:name="android.permission.CAMERA" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
