video_examples +\ingroup camera_examples +\meta {tag} {widgets} +\brief Shows how to capture a still image or record video. +or video. + +The Camera Example demonstrates how you can use \l{Qt Multimedia} to implement +some basic Camera functionality to take still images and record video clips +with audio. + +\include examples-run.qdocinc + +The example implements a \c Camera class that acts as our camera interface. 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 uses: +\list + \li An instance of \l {QCamera}, the API class interface to the hardware. + \li An instance of \l {QImageCapture} to take still images. + \li An instance of \l {QMediaRecorder} to record video. It also contains + the user interface object. +\endlist + +The Camera constructor does some basic initialization: +\list + \li The user interface is initialized. + \li UI signals are connected to slots that react to the triggering event. +\endlist +However, most of the work is done when the \e{setCamera()} function is called, +passing in a \l QCameraDevice. + +\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 {QImageCapture}, 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 can be a 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 preview and lock the camera settings. \c Key_Camera will +either call \e{takeImage()} if doing an image capture, or call +\c record() or \c stop() (if already recording) on the QMediaRecorder instance +when recording video. + +\image camera-example.png + +*/ diff --git a/examples/multimedia/camera/images/shutter.svg b/examples/multimedia/camera/images/shutter.svg new file mode 100644 index 000000000..18493361d --- /dev/null +++ b/examples/multimedia/camera/images/shutter.svg @@ -0,0 +1,21 @@ +<?xml version="1.0" encoding="utf-8"?> +<!-- Generator: Adobe Illustrator 20.1.0, SVG Export Plug-In .
