Hey Ugo, Bill,

I have tested the linked branch. 2 issues:

* My BQ is running out of space and produces the "Low disk space"
warning when the camera app starts up. That seems to steal focus which
forces me to first swipe to the foto roll and back to the viewfinder in
order to fix the focus things.

* Second, don't ask me why, but that exact same selfie stick I tried
half a year ago, now seems to produce this keycode: 0x1008FF16 which
isn't listed in the Qt namespace. However, it is listed in xkbcommon-
keysyms.h and is mapped to XKB_KEY_XF86AudioPrev. To make things even
weirder, I have to add that this is on krillin. Last time I tested it on
flo. However, I retested it on flo right now and believe it or not, it's
XKB_KEY_XF86AudioMedia (0x1008FF32) now. I've also tested that same
stick on an iPhone, it will  increase the sound volume when the camera
app was not focused. So this means that the generated keycode depends on
the hardware drivers, in our case the Android HAL. Different devices and
versions of the Android image can change the produced keycode.

This makes me believe that we should just handle all common multimedia
keys in the camera app to trigger the shutter. If we add those keys, I
guess we should support most of the cases:

0x1008FF14 (XKB_KEY_XF86AudioPlay)
0x1008FF15 (XKB_KEY_XF86AudioStop)
0x1008FF16 (XKB_KEY_XF86AudioPrev)
0x1008FF17 (XKB_KEY_XF86AudioNext) 
0x1008FF31 (XKB_KEY_XF86AudioPause)
0x1008FF32 (XKB_KEY_XF86AudioMedia)

Qt::Key_MediaPlay	0x01000080	
Qt::Key_MediaStop	0x01000081
Qt::Key_MediaPrevious	0x01000082	 
Qt::Key_MediaNext	0x01000083	 
Qt::Key_MediaRecord	0x01000084	 
Qt::Key_MediaPause	0x1000085
Qt::Key_MediaTogglePlayPause	0x1000086

Title:
  Selfie stick not supported

Status in Canonical System Image:
  In Progress
Status in camera-app package in Ubuntu:
  In Progress

Bug description:
  I had a chance to play with a selfie stick: http://bit.ly/1KIYkBc

  Working fine on iOS it didn't do anything on Ubuntu.  I had enough
  time to check out what what keycode it sends when pressing the shutter
  button: Qt.Key_MediaTogglePlayPause

  So I guess all it takes is to add a Keys.onPressed handler to the
  camera app and trigger the photo shutter or start/stop recording when
  in video mode.
