I am trying to design a VCR with front and rear camera. The app can switch between the rear (default) and front camera. When the application is activated on the front camera, and I press the record button, the application switches to the error method, and I release and start the camera and recording, but the error is saved another time. Any ideas? UPDATE: I update the onError method with the code below, and I think that I do not release and the camera with init is good, because when the application executes this method, the surface holder is black and does not give me what the camera sees
Here is my code:
onError:
public void onError(MediaRecorder mr, int what, int extra) {
stopRecording();
if (what == 100) {
if (error_100 == 2) {
if (Camera.getNumberOfCameras() <= 1) {
} else {
if (selected_camera == FRONT_CAMERA) {
selected_camera=BACK_CAMERA;
} else {
selected_camera=FRONT_CAMERA;
}
selected_camera_button.setEnabled(false);
Toast.makeText(this, "Initializing other camera", Toast.LENGTH_SHORT).show();
}
} else {
if (error_100 == 3) {
Toast.makeText(this, "Initialize cameras failed", Toast.LENGTH_SHORT).show();
finish();
} else {
Toast.makeText(this, "Recording error has occurred. Stopping the recording", Toast.LENGTH_SHORT).show();
}
}
error_100++;
initCamera();
initCameraRecorder();
}
}
And another method:
private boolean initCamera() {
try {
camera = getCameraInstance(selected_camera);
Camera.Parameters camParams = camera.getParameters();
camParams.set( "cam_mode", 1 );
camParams.set("orientation", "portrait");
checkCameraFlash(camParams);
setAngleCameraRotation();
camera.setDisplayOrientation(angle_rotation_camera);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
Establish 4:3 ratio and 480x640 if is posible
setAspectResolutionCamera(camParams);
camera.setParameters(camParams);
video_view.getHolder().setFixedSize(height_video, width_video);
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(height_video, width_video);
video_view.setLayoutParams(lp);
camera.lock();
surface_holder = video_view.getHolder();
surface_holder.addCallback(this);
surface_holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
setPreviewCamera();
} catch(Exception e) {
Log.v("RecordVideo", "Could not initialize the Camera");
return false;
}
return true;
}
private void initCameraRecorder() {
if(media_recorder != null) return;
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
output_file_name = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM) + File.separator + timeStamp + ".mp4";
File outFile = new File(output_file_name);
if(outFile.exists()) {
outFile.delete();
}
try {
camera.stopPreview();
camera.unlock();
media_recorder = new MediaRecorder();
media_recorder.setCamera(camera);
media_recorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
media_recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
CamcorderProfile profile = CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH);
profile.videoBitRate = 885000;
profile.videoFrameHeight = height_video;
profile.videoFrameWidth = width_video;
media_recorder.setProfile(profile);
media_recorder.setMaxDuration(21000);
media_recorder.setOrientationHint(setOrientationCameraRecorder());
media_recorder.setPreviewDisplay(surface_holder.getSurface());
media_recorder.setOutputFile(output_file_name);
media_recorder.prepare();
Log.v("RecordVideo", "MediaRecorder initialized");
} catch(Exception e) {
Log.v("RecordVideo", "MediaRecorder failed to initialize");
e.printStackTrace();
}
}
private void beginRecording() {
media_recorder.setOnInfoListener(this);
media_recorder.setOnErrorListener(this);
media_recorder.start();
record_button.setTextColor(getResources().getColor(android.R.color.holo_red_dark));
}
private void stopRecording() {

}
