- * This class is the implementation of MP3 format.This forms a part of

- * plugin mimetype : audio/mpeg This is to be passed as the default data 
- * while creation of player
- * 
- * @code
- *
- * //mimetype is buffer with audio/mpeg as data

- *                 //this is should have filled buffer when you call Intialize
- * CIRCtrlCmdObserver* aChannel; //command channel dll's instant
- * TInt volume;
- * iPlayer->Intialize(config,buffer,channel);
- * iPlayer->Play();//to play
- * iPlayer->Stop();//to stop
- * iPlayer->SetVolume(volume);//set the volume
- * iPlayer->Volume;// returns current volume
- * iPlayer->MaxVolume();//return maximum volume
- * iPlayer->StopPlayerBuffering();//stop buffering if required
- * iPlayer->StartPlayerBuffering();//start buffering (incase if stop you can restart with this method)
- * iPlayer->BufferFilled(); //should be called when the buffer given by player is return
- *                     //this will mark the buffer as filled
