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. With this example an image can be opened either from the device memory or a memory card (if present). Once opened, the image can be rotated, scaled, and saved in the same or a different format (for example, a JPG image can be converted into a GIF image). The UI of the updated application has been optimized for touch. For example, long taps and tactile feedback are supported. 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.
S60 5th Edition: What’s New for Developers
This document provides developers with a summary of the new features in the initial release of S60 5th Edition. The document describes the changes to the UI and the new features available to developers using Symbian C++, Open C/C++, Java™ technology, Web Runtime (WRT), and Flash Lite from Adobe. It also covers support for additional content formats.
S60 Platform: Developers’ Introductory Guide
This version of S60 Platform: Developers’ Introductory Guide provides information about the platform through the initial release of S60 5th Edition. It describes the architecture of the S60 platform, provides an overview of the available runtime and content technologies, outlines the tools available for developers, and offers a guide to the support services provided by Forum Nokia.
S60 Platform: Camera Example with Autofocus Support
This C++ application implements the basic features of the built-in camera using the On-board Camera API classes MCameraObserver and CCamera (supported from S60 2nd Edition onwards). Also auto focus is supported via an AF extension library provided in the package (supported in S60 3rd Edition, FP1).
S60 Multimedia Framework eLearning
This eLearning module provides the developer with a client’s view of the Multimedia Framework and the APIs or interfaces available to use when writing applications. It begins with a look at the architecture of the Multimedia Framework, and then goes on to discuss the Client APIs supported by the Multimedia Framework, namely the Audio Interface, the Tone player Interface, the Audio Streaming interface and the Video Interface. The eLearning module concludes with a demonstration showing how to use one of the client APIs.
S60 Platform: Full-Duplex Audio Example v2.0
This C++ example application plays and records audio simultaneously, reading from the microphone and writing to the earpiece/speaker, creating a local audio feedback loop. Audio is processed in encoded format, using real-time encoding/decoding support from audio hardware. This example can also be used for creating VoIP applications on S60 2nd Edition, S60 2nd Edition FP2 and FP3.
Main classes: CMMFDevSound, MDevSoundObserver.
S60 Platform: Music Application Developer's Guide
This document provides guidance on using S60 multimedia APIs to create music applications for S60 3rd Edition and future devices. The document contains descriptions and examples that illustrate the use of multimedia APIs to accomplish common operations for music applications. In addition, this document covers alternative techniques for accomplishing similar operations while explaining the design tradeoffs between the different approaches.
S60 Platform: Video Example v2.0
This C++ code example demonstrates how to play and record video files.
CVideoRecorderUtility and CCamera classes are used to record a video clip, and the CVideoPlayerUtility class is used to play, stop, and pause video clips and show the video clip information. In addition, playing a video clip in an external viewer using a document handler method is demonstrated in this example.
Video APIs are part of the Multimedia Framework (MMF) that is supported from Symbian OS v7.0s (S60 2nd Edition) onwards (on the Nokia 6600 it is only possible to play video).
Main classes: CVideoRecorderUtility, CVideoPlayerUtility, CCamera, CFeatureDiscovery.
S60 Platform: Audio Streaming Example v2.0
Audio Streaming Example demonstrates the use of Audio Streaming API that provides functionality for recording audio stream into a buffer and playback of the audio buffer. Besides playing, recording, and stopping the audio stream, the recorded audio stream can be saved into a file and further loaded to be played again. PCM and AMR-NB-encoded sample files are included in the package. Audio Streaming API is part of the Symbian Multimedia Framework (MMF) and supported from S60 2nd Edition onwards. Main classes: CMdaAudioInputStream, CMdaAudioOutputStream, MMdaAudioInputStreamCallback, MMdaAudioOutputStreamCallback.
S60 Platform: Sound Mixer Example v2.0
This updated example application demonstrates how to play a maximum of 16 simultaneous voices. The example has eight blocks moving on the screen and playing sounds when they hit a wall or each other.
S60 Platform: Audio Output Streaming Example v1.1
This updated C++ example application demonstrates the key functionalities of the Audio Streaming API by playing generated waveforms and pcm sound data from a file.
Nokia 7710: In-Depth Developer's Guide
This documentation package gives you a comprehensive look inside the Nokia 7710 multimedia smartphone. It starts with the UI framework, going through instructions on how to build applications, and finally discusses porting existing software to the Nokia 7710.
Series 60 Platform 1st/2nd Edition: Call Recorder Example
This example shows how to record phone calls (from a telephony uplink and a microphone) into wav files. In addition, the example demonstrates how to play audio files, show a progress bar, and use active objects to listen to the phone line.
Symbian OS: Creating Audio Applications In C++
This document describes how to use the capabilities of Symbian OS to record and play audio content.
Symbian OS: Multimedia Framework And Other Multimedia APIs
This document describes the multimedia framework (MMF) introduced in Symbian OS v7.0s as well as the related servers and libraries that are commonly used in multimedia applications. This document is mainly considered as background information on how the multimedia system is implemented in Symbian OS, since developers do not typically write their code to run directly within that framework.
