Making a preview window for the camera in an app

Question

Is it possible to have a preview function within the app of what the mobile camera is seeing? Or is this option only possible to code in Eclipse or similar programs?

Using the camera component in XE5 only opens the inbuilt camera app, not displaying the view within the app..

Primarily Android..

Thanks

Not sure why the downvote, sure seems like an adequate question. — Jerry Dodge, Feb 25 '14 at 16:23
Android, iOS, or both? I know Mitov has a live video feed component, but am not certain which platforms they support. — Martijn, Feb 26 '14 at 09:31
Primarily Android for now.. Do you have any ideas if RAD studio XE5 Delphi can create apps with the same features as thosed made in Eclipse, Titanium etc? Or does it have limitations? — JohnGallo2, Feb 26 '14 at 12:25
There are limitations, but you can extend it. You have access to the source. Titanium also has limitations. — Marcus Adams, Mar 04 '14 at 15:20

It is very easy - you have to define procedure that will be assigning camera buffer to TImage.Bitmap. OnSampleBufferToBitmap event handler can look like:

procedure TForm240.SampleBufferReady(Sender: TObject; const ATime: TMediaTime);
begin
  VideoCamera.SampleBufferToBitmap(Image1.Bitmap, True);
end;

It is taken from official example for Video Capture: http://sourceforge.net/p/radstudiodemos/code/HEAD/tree/branches/RadStudio_XE5_Update/FireMonkey/Delphi/VideoCaptureHD/

Tested by me and works on few devices.
