Description

The N96 uses hardware codecs which require additional settings compared to other S60 devices. When the DevVideo Record example is run on the Nokia N96, the application fails with the KErrNotReady (-18) error while calling CMMFDevVideoRecord::WritePictureL(), or with KErrNotSupported (-5) if the camera has been set as the video source with CMMFDevVideoRecord::SetSourceCameraL().

How to reproduce

The DevVideo Record example can be used to reproduce the problem on the Nokia N96.

Solution

To ensure that MDF DevVideo encoders work on the Nokia N96, call the CMMFDevVideoRecord::SetRateControlOptions() function in MMMFDevVideoRecordObserver::MdvroInitializeComplete before calling CMMFDevVideoRecord::Start().

 void CDevvideoExAppUi::MdvroInitializeComplete( TInt aError )
{
if ( aError != KErrNone )
{
// TODO: Handle errors
return;
}
 
// Set rate control options
TRateControlOptions rateCtrl;
rateCtrl.iControl = EBrControlNone;
rateCtrl.iPictureQuality = 0;
rateCtrl.iBitrate = iBitRate;
rateCtrl.iPictureRate = iFrameRate;
rateCtrl.iQualityTemporalTradeoff = 0;
rateCtrl.iLatencyQualityTradeoff = 0;
iDvr->SetRateControlOptions( 0, rateCtrl );
 
// Start encoding
iDvr->Start();
 
// Write first input picture
iPicNum = 0;
WritePic();
}
