The \l {QML Camera Example} demonstrates still image capture and controls
using the QML plugin. Video recording is not currently available.
\section2 QML Video Example
The \l {video/qmlvideo}{QML Video 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 as a semi-transparent item overlaid
on the video content.
\section2 QML Video Shader Effects Example
The \l {video/qmlvideofx}{QML Video Shader Effects Example} shows how the
\l {ShaderEffect} element can be used to apply postprocessing effects,
expressed in GLSL, to QML \l {VideoOutput} items.
It re-uses the frame rate display code used by the \l {QML Video Example}.
Finally, this application demonstrates the use of different top-level QML
files to handle different physical screen sizes. On small-screen devices,
menus are by default hidden, and only appear when summoned by a gesture.
Large-screen devices show a more traditional layout in which menus are
displayed around the video content pane.
