Droidmedia supports a callback to indicate the exact moment when the shutter fires, and this is passed on as a GstMessage by Gst-droid. There is already an imageExposed signal being emitted from QGstreamerCaptureSession, but it's only sent when the image is finished, right before imageCaptured. This class already parses GstMessages, so we can move the imageExposed signal to be sent when the shutter actually fires. This can trigger the shutter sound and animation in camera apps as intended.
