+\title Camera Example
+\ingroup camera_examples
+\brief The Camera Example shows how to use the API to capture a still image
+or video.
+
+
+
+The Camera Example demonstrates how you can use QtMultimedia to implement
+some basic Camera functionality to take still images and record video clips
+with audio.
+
+A Camera class is created that will act as our Camera. It has a user interface,
+control functions, setting values and a means of defining the location where
+the image or video clip is to be saved. It will also store the image and video
+settings.
+
+The Camera class contains an instance of \l {QCamera}, the API class interface to
+the hardware. It also has an instance of \l {QCameraImageCapture} to take still images
+and an instance of \l {QMediaRecorder} to record video. It also contains the user
+interface object.
+
+The Camera constructor does some basic initialization. The camera object is
+set to '0', the user interface is initialized and UI signal are connected to
+slots that react to the triggering event. However, most of the work is done when
+the \e{setCamera()} function is called, passing in a \l {QByteArray}.
+
+\e{setCamera()} sets up various connections between the user interface and the functionality
+of the Camera class using signals and slots. It also instantiates and initializes the \l {QCamera},
+\l {QCameraImageCapture} and \l {QMediaRecorder} objects mentioned above. The still
+and video recording visual tabs are enabled and finally the
+\l {QCamera::start()}{start()} function of the \l{QCamera} object is called.
+
+Now that the camera is ready for user commands it waits for a suitable event.
+Such an event will be the key press of either the \l {Qt::Key_CameraFocus} or
+\l {Qt::Key_Camera} buttons on the application window. Camera focus will
+simply display the viewfinder and lock the camera settings. Key_Camera will
+either call \e{takeImage()} if the \l {QCamera::captureMode()}{captureMode()}
+is QCamera::CaptureStillImage, or if the capture mode is for video then one
+of two actions will occur. If the recording state shows that we are currently
+recording then the \e{stop()} function is called resulting in a call to
+\l {QCamera::stop()}, whereas if we are not recording then a video recording
+is started with a call to \l {QMediaRecorder::record()}.

+\example declarative-camera
+\title QML Camera Example
+\ingroup camera_examples_qml
+
+\brief The Camera Example shows how to use the API to capture a still image
+or video.
+
+\image qml-camera.png
+
+This example demonstrates how to use the Qt Multimedia QML API to access
+camera functions. It shows how to change settings and to capture images.
+
+Most of the QML code supports the user interface for this application with the
+camera types being mostly found in \e {declarative-camera.qml} and
+\e {CaptureControls.qml}.
+
+In \e {declarative-camera.qml} the \l Camera is initialized with an id
+of \e {camera}, a photo preview is setup, states are implemented for image
+preview or capture and \l CaptureControls is initialized. The initial
+\e state is \e PhotoCapture. \l CameraCapture includes a handler, \e onImageCaptured,
+for the \l {imageCaptured} signal. The handler sets up the application to process
+the preview including a change in the user interface state. The \l PhotoPreview
+becomes visible with any key press being picked up by the handler
+in PhotoPreview and returning the state to \e PhotoCapture.
+
+\e CaptureControls, which is implemented in \e {CaptureControls.qml},
+generates a column on the right hand side of the screen which includes control
+buttons for \e focus (not initially visible), \e {capture}, \e {flash modes},
+\e {white balance}, \e {exposure compensation}, and if a preview is
+available a \e {preview} button. The last button exits from the application.
+
+When the Capture button is pressed the \e onClicked handler calls
+\l {Camera::captureImage()}{captureImage()}
+

+/*!
+ \example player
+ \title Media Player Example
+ \ingroup video_examples
+
+
+ This example creates a simple multimedia player. We can play audio and
+ or video files using various codecs.
+
+ The example uses a QMediaPlayer object passed into a QVideoWidget to
+ control the video output. To give the application playlist capability
+ we also use a QPlayList object.
+
+ To activate the various functions such as play and stop on the dialog
+ we connect clicked() signals to slots that emit the play() and stop()
+ signals and in turn which we connect to the play() and stop() slots in
+ QMediaPlayer.
+
+ \code
+ connect(controls, SIGNAL(play()), player, SLOT(play()));
+ connect(controls, SIGNAL(pause()), player, SLOT(pause()));
+ connect(controls, SIGNAL(stop()), player, SLOT(stop()));
+ \endcode
+
+ We can get the volume (and set our user interface representation)
+
+ \code
+ controls->setVolume(player->volume());
+ \endcode
+
+ and we can make widget 'volume' changes change the volume
+
+ \code
+ connect(controls, SIGNAL(changeVolume(int)), player, SLOT(setVolume(int)));
+ \endcode
+
+ The example also allows us to change various video properties by means
+ of the QVideoWidget object. We can go to Full Screen mode with a single
+ button click, and back again. Or if we press the "Color Options" dialog
+ button we can have access to more subtle influences. The dialog has a
+ set of sliders so that we can change the brightness, contrast, hue and
+ saturation of the video being watched. The connect() statements are in
+ pairs so that changes to either the user interface widget (the relevant
+ slider) or the QVideoWidget object will update the other object.
+
+ \code
+ connect(brightnessSlider, SIGNAL(sliderMoved(int)), videoWidget,
+ SLOT(setBrightness(int)));
+ connect(videoWidget, SIGNAL(brightnessChanged(int)),
+ brightnessSlider, SLOT(setValue(int)));
+
+ connect(contrastSlider, SIGNAL(sliderMoved(int)), videoWidget,
+ SLOT(setContrast(int)));
+ connect(videoWidget, SIGNAL(contrastChanged(int)), contrastSlider,
+ SLOT(setValue(int)));
+
+ connect(hueSlider, SIGNAL(sliderMoved(int)), videoWidget,
+ SLOT(setHue(int)));
+ connect(videoWidget, SIGNAL(hueChanged(int)), hueSlider,
+ SLOT(setValue(int)));
+
+ connect(saturationSlider, SIGNAL(sliderMoved(int)), videoWidget,
+ SLOT(setSaturation(int)));
+ connect(videoWidget, SIGNAL(saturationChanged(int)),
+ saturationSlider, SLOT(setValue(int)));
