Multimedia On Symbian OS: Inside The Convergence Device
Multimedia on Symbian OS is the only book available to discuss multimedia on Symbian OS at this level. It covers key areas of multimedia technology, with information about APIs and services provided by Symbian OS. Other key features include details of UI platform-specific APIs from S60 and UIQ.
This pioneering book covers
each of the key technologies available (such as audio, video, radio, image conversion, tuner and camera) at a high level, to give the reader context, before drilling down to details of how to use each of them. The book includes code samples which are available for download on a website and cover key APIs with detailed description of each. Additional information includes the evolution of multimedia on Symbian OS from previous versions to the current (v9.5) and plans for the future.
Chapters include:
* Architecture of Multimedia on Symbian OS
* Onboard Camera
* Multimedia Framework of both Video & Audio
* Image Converter Library
* The Tuner
