Qt for S60 QPlugin Example
This Qt C++ example application demonstrates how to extend an application with Qt plug-ins. This involves defining a common Qt plug-in interface in the GUI application and implementing media plug-ins for S60 devices. The plug-ins are installed separately, after which the client application detects installed plug-ins and content specific to plug-ins is searched for. QPlugins can be used already from S60 3rd Edition, FP1 onwards. However, with the Qt for S60 4.5.0 Garden release, the application UI has been tested to work better on S60 5th Edition touch UI devices. The QPlugin example is based on the DesktopServices example published in the Qt for S60 4.5.0 Garden release. Important classes: QDesktopServices, QMainWindow.
Qt for S60: QSimpleImageViewer Example
This Qt C++ application demonstrates how to use QPixmap to show images on the screen. The application has S60 style menus, status pane and control pane. The application runs on S60 devices based on S60 3rd Edition, Feature Pack 1 and newer releases, and supports both touch UI and keyboard. Important classes: QPixmap, QMainWindow, QProcess.

Symbian C++ - Multimedia
S60 Platform: Camera Example
This Symbian C++ code example demonstrates how to easily use the onboard camera with zoom and autofocus, utilising an accompanying CameraWrapper made by Forum Nokia. The Camera Wrapper supports all Nokia's S60 devices based on S60 3rd Edition and newer, providing a unified interface for various Symbian and S60 camera APIs some of which have previously been Feature Pack specific or only available via an SDK plug-in. The example application supports the use of both the keypad and touch UI. The application can be self-signed, but it also provides an option to use the dedicated camera key (Symbian signing required). The example application replaces the separate examples published for S60 3rd Edition, FP1 (S60 Platform: Camera Example with AutoFocus Support v2.2) and FP2 (S60 Camera Example AutoFocus 3rd Ed FP2).
S60 Platform: Audio Streaming Example
This C++ example application demonstrates the use of Audio Streaming API, which provides functionality for recording audio stream into a buffer, and for playback of the audio buffer. Besides playing, recording, and stopping the audio stream, the recorded audio stream can be saved into a file, to be played again later. The package includes PCM and AMR-NB encoded sample files. Audio Streaming API is part of the Symbian Multimedia Framework (MMF). The updated example has been tested to support S60 5th Edition and touch UI. Important classes: CMdaAudioInputStream, CMdaAudioOutputStream, MMdaAudioInputStreamCallback,
MMdaAudioOutputStreamCallback.
S60 Platform: Audio Output Streaming Example
This updated C++ example application demonstrates the key functionalities of the
Audio Streaming API by playing generated waveforms and Pulse-Code Modulation (PCM) sound data from a file. The updated example has been tested to support S60 5th Edition and touch UI. Important classes: CStreamAudioEngine, CMdaAudioOutputStream, MMdaAudioOutputStreamCallback.
S60 Platform: Sound Mixer Example
This C++ example demonstrates how to play (a maximum of 16) simultaneous voices.
The example has eight blocks moving on the screen and playing sounds when they
collide with a wall or with each other. The updated example has been tested
to support S60 5th Edition and touch UI. Important classes: CMdaAudioOutputStream, TMdaAudioDataSettings, MMdaAudioOutputStreamCallback, RThread, RSemaphore, RMutex
Multimedia in the S60 Platform
The Multimedia section of the S60 5th Edition C++ Developer's Library explains what needs to be taken into account when developing multimedia applications for S60 devices.
S60 Platform: Image Converter Example
This example demonstrates how to use the image conversion APIs available in the S60 platform (Image Conversion Library, ICL). These APIs include important classes, such as CBitmapRotator and CBitmapScaler to be used for rotating and scaling images, respectively. CImageEncoder and CImageDecoder classes are used to access image encoders and decoders available in the ICL. Images can be opened, rotated, scaled, and saved in the same or a different format. The UI of the updated application has been optimised for touch using, for example, long taps and tactile feedback. The example project supports building for both S60 5th Edition with touch UI and S60 3rd Edition with a traditional keypad. Important classes: CAknLongTapDetector, MTouchFeedback, CBitmapRotator, CBitmapScaler, CImageEncoder, CImageDecoder, CFbsBitmap, CAknQueryDialog.
