The CMPMediaPlayerSettings application provides the Media Settings UI, where the user can control the volume and playing mode of the file. The SetAutoDisconTimeL(TInt) can be used to automatically discontinue playing the file after a given period of time.

Below is the example code of CMPMediaPlayerSettings usage.

void CTestMPSettingsAppUi::ContructL()
{
...
 CMPMediaPlayerSettings* iSetting = CMPMediaPlayerSettings::NewL();
...
}
 
void CTestMPSettingsAppUi::ControlVolumeLevelL()
{
    //Returns Media Player volume level.
    TInt i = iSetting->VolumeLevelL();
 
    //Sets Media Player volume level. Ranges between 1-10.
    iSetting->SetVolumeLevelL(8);
 
}
void CTestMPSettingsAppUi::ControlMutedL()
{
    //Sets Media Player in Mute mode.
    iSetting->SetMutedL(ETrue);
 
    //Returns true if Media Player is in Mute mode. 
    iSetting->IsMutedL()   
}
 
void CTestMPSettingsAppUi::ControlAutoDisconTimeL()
{
    //Sets Media Player auto disconnection time to 10 mins.
    //Ranges between 1-99, Time in minutes
    iSetting->SetAutoDisconTimeL(10);
 
    //Returns Media Player auto disconnection time.
    //disconTime contains auto disconnection time.
    TInt disconTime = iSetting->AutoDisconTimeL();   
}
