\o Services built on top of these APIs would include Internet

applications such as email and web browsing.

\o Multimedia features enable image and video capture with audio ,

\o Location will make the device aware of its geographical location

to support GIS applications.

\o Publish-Subscribe enables communication between separate objects

are proud of the work we have done on this project and want to show

not only what we are delivering now but what is around the corner.

On all platforms, QML elements for sound effects and music and video playing are exported if QtDeclarative (auto-detected) is available.

On all platforms, additional rendering paths are enabled of QtOpenGL (auto-detected) is available.

The gstengine plugin for Linux and Maemo depends on gstreamer-0.10 (>= 0.10.19), gstreamer-audio-0.10 (>= 0.10.19), gstreamer-base-0.10 (>= 0.10.19), gstreamer-interfaces-0.10 (>= 0.10.19) and gstreamer-video-0.10 (>= 0.10.19).

If asound (auto-detected) is available, ALSA device detection will be enabled.

The QtMobilityMultimediaEngine for Symbian depends on QtMultimedia.

To enable all mediaservices on symbian one must download sdk plugins. Sdk plugins are available at \l http://wiki.forum.nokia.com/index.php/SDK_API_Plug-in

For 5th edition sdk plugins are installed with installer (all at once), but for FP1 and FP2 devices a zip is provided. You will need following plugins to compile all features:

Multimedia provides a set of APIs that allow the developer to play, record

and manage a collection of media content. It is dependent on the

QtMultimedia API. This API is planned to replace Phonon at a later stage.

\section2 Video

For playing and manipulating video sources the API enables us to easily

implement a player application. If we examine the \l{player}{Player}

example we see that the implementation of a simple media player requires a

\o The Symbian Settings layer provides a permanent Value Space backing store using the

Symbian OS' Properties (RProperty) as well as Central Repository files (CRepository).

The Symbian Settings layer has an order of 0.

\endtable

The Value Space has support for both client/server and peer-to-peer layer architectures. If a

is transparent operation to the API user but may cause interoperatibility issues with native Symbian codes

that access the same data directly. The maximum size of the bytearray is 65535 for RPropery backing store.

\section1 Examples

\section2 Publish and Subscribe

\o Play video from local file.

\o Retrieve meta data information from currently playing media. Following tags supported: title, artist, comment, genre, year, copyright, album, composer, albumtrack, audiobitrate, videobitrate, duration, content type.

\o Media recording: audio capture to specified file from phone microphone or phone call (call needs to be started before media recording).
