-\title QML Video Example
-\ingroup video_examples_qml
-
-\brief The QML Video Example demonstrates the various manipulations (move;
-resize; rotate; change aspect ratio) which can be applied to QML \l{VideoOutput}
-items.
-
-\section1 Overview
-
-This example demonstrates the various manipulations (move; resize; rotate;
-change aspect ratio) which can be applied to QML \l{VideoOutput} items.
-
-It also shows how native code can be combined with QML to implement more
-advanced functionality - in this case, C++ code is used to calculate the QML
-frame rate. This value is rendered in QML in a semi-transparent item
-overlaid on the video content.
-
-The following image shows the application executing the video-overlay scene,
-which creates a dummy overlay item (just a semi-transparent \l{Rectangle}),
-which moves across the \l{VideoOutput} item.
-
-\image qmlvideo-overlay.png
-
-\section1 Application structure
-
-The \l{video/qmlvideo/qml/qmlvideo/main.qml} file creates a UI which includes
-the following items:
-
-\list
- \li Two \l{video/qmlvideo/qml/qmlvideo/Button.qml}{Button} instances, each
- of which displays a filename, and can be used to launch a
- \l{video/qmlvideo/qml/qmlvideo/FileBrowser.qml}{FileBrowser}
- \li An exit \l{video/qmlvideo/qml/qmlvideo/Button.qml}{Button}
- \li A \l{video/qmlvideo/qml/qmlvideo/SceneSelectionPanel.qml}{SceneSelectionPanel},
- which is a flickable list displaying the available scenes
- \li At the lower left, an item which displays the QML repainting rate - the
- upper number is the instantaneous frame rate and the lower number is the
- average over the past second.
-\endlist
-
-\image qmlvideo-menu.png
-
-Each scene in the flickable list is implemented in its own QML file - for
-example the video-basic scene (which just displays a static \l{VideoOutput}
-in the center of the screen) is implemented in the
-\l{video/qmlvideo/qml/qmlvideo/VideoBasic.qml}{VideoBasic.qml} file. As you
-can see from the code, this makes use of a type of inheritance: a
-\l{video/qmlvideo/qml/qmlvideo/VideoBasic.qml}{VideoBasic} item ...
-
-\quotefromfile video/qmlvideo/qml/qmlvideo/VideoBasic.qml
-\skipto import
-\printuntil /^\}/
-
-... is-a
-\l{video/qmlvideo/qml/qmlvideo/SceneBasic.qml}{SceneBasic} ...
-
-\quotefromfile examples/video/qmlvideo/qml/qmlvideo/SceneBasic.qml
-\skipto import
-\printuntil contentType
-\dots
-\skipto Content
-\printuntil content
-\dots
-\skipto }
-\printuntil /^\}/
-
-... which is-a
-\l{video/qmlvideo/qml/qmlvideo/Scene.qml}{Scene}:
-
-\quotefromfile video/qmlvideo/qml/qmlvideo/Scene.qml
-\skipto import
-\printuntil root
-\dots
-\skipto property QtObject content
-\printuntil content
-\dots
-\skipto Button
-\printuntil /^\}/
-
-\l{video/qmlvideo/qml/qmlvideo/SceneBasic.qml}{SceneBasic} describes the
-structure and behaviour of the scene, but is agnostic of the type of content
-which will be displayed - this is abstracted by
-\l{video/qmlvideo/qml/qmlvideo/Content.qml}{Content}.
-
-This pattern allows us to define a particular use case (in this case, simply
-display a static piece of content), and then instantiate that use case for
-both video content
-(\l{video/qmlvideo/qml/qmlvideo/VideoBasic.qml}{VideoBasic}) and cameracontent
-(\l{video/qmlvideo/qml/qmlvideo/CameraBasic.qml}{CameraBasic}). This approach
-is used to implement many of the other scenes - for example, "repeatedly slide
-the content from left to right and back again" is implemented by
-\l{video/qmlvideo/qml/qmlvideo/SceneMove.qml}{SceneMove}, on which
-\l{video/qmlvideo/qml/qmlvideo/VideoMove.qml}{VideoMove} and
-\l{video/qmlvideo/qml/qmlvideo/CameraMove.qml}{CameraMove} are based.
-
-Depending on the value of the contentType property in the top-level scene
-instance, the embedded
-\l{video/qmlvideo/qml/qmlvideo/Content.qml}{Content} item creates either a
-\l{MediaPlayer} or a \l{Camera} item.

-
-All that remains is to connect the afterRendering() signal of the QQuickView
-object to a JavaScript function, which will eventually call frequencyItem.notify():
-
-\quotefromfile video/qmlvideo/main.cpp
-\skipto QmlApplicationViewer
-\printuntil ;
-\dots
-\skipto QQuickItem
-\printuntil ;
-\dots
-\skipto QObject::connect
-\printuntil SLOT(qmlFramePainted()));
