It's not possible to disable the camera shutter sound in QML's Camera component

The fact that the shutter sound when taking a camera picture is in the abstraction layer, forces that sound to be played every time a shot is taken with the QML Camera component.

This means app developers cannot disable or override the shutter sound in their apps. One use case for this I encountered was while writing a QR code application that continuously takes shots and analyzes the image to scan a QR code. The fact that the shutter sound is played continuously prevents me from being able to use the QML camera component.

<rsalveti> dpm: the sound file itself is available in the android system partition, and used by the app, let me find the code
<rsalveti> qtubuntu-camera-0.3.3+13.10.20130919.2/src/aalimagecapturecontrol.cpp
 m_audioPlayer->setMedia(QUrl::fromLocalFile("/system/media/audio/ui/camera_click.ogg"));

So after a conversation with rsalveti and jhodapp it seems that the shutter sound is only required by the camera app, but for some reason rather than put it in the camera app itself, it was added to the abstraction layer. Their suggestion was to file a bug to remove the sound from the abstraction layer and put it in the app, so that app developers can use the upstream QML component and be able to decide whether to play a sound and which one.
