QtMultimedia | Although the module itself is supported, no backend for Symbian is currently available. However, there is a backend available for Phonon. |
Known issues can be found by visiting the wiki page with an up-to-date list of known issues, and the list of bugs can be found by browsing the S60 component in Qt's public task tracker, located at http://bugreports.qt.nokia.com/.

The Qt libraries are typically signed with All -TCB capabilites, but that does not mean your Qt application needs to be signed with the same capabilities to function properly. The capabilities your application needs to function properly depends on which parts of Qt you use, here is an overview:
Module | Required Symbian Capability |
---|---|
QtCore | PowerMgmt if QProcess::kill(...) or QProcess::terminate(...) is called. |
QtCore | AllFiles when accessing specific areas. |
QtNetwork | NetworkServices is basically always required for this module. |
QtMultiMedia | UserEnvironment if QAudioInput is used. |
Note that some modules rely on other modules. If your application uses QtXmlPatterns, QtWebkit or QtScript it may still require NetworkServices
as these modules rely on QtNetwork to go online.
For more information see the documentation of the individual Qt classes. If a class does not mention Symbian capabilities, it requires none.
Qt provides a backend for Qt's Phonon module, which supports video and sound playback through Symbian's Multimedia Framework, MMF.
In this release the support is experimental. Video playback may have flickering issues, and support for effects and playback queueing is incomplete.
The audio and video formats that Phonon supports depends on what support the platform provides for MMF. The emulator is known to have limited codec support.
In addition, there exists a backend for the Helix framework. However, due to it not shipping with Qt, its availability depends on the Symbian platform in use. If available, it is loaded in preference over the MMF plugin. If the Helix plugin fails to load, the MMF plugin, if present on the device, will be loaded instead.
