Missing MetadataUtility Class in 3rd edition

[fabrizioe]

On december 16th was published by Nokia a document concerning Music services.
It describes also a way to extract tags from media files (title, album,...) using CMetadataUtility class that avoid the resource consuming use of player utility class.

My question is: Where is this class?? In the FINAL version of 3rd Edition SDK there is no mention in the help and no header file contains CMetadataUtility.

I hope that some Forum Nokia Expert look at this post....

Did anyone working on 3rd Edition notice that some classes regarding metadata parsing of media files are missing?

Is this forum sponsored by Nokia or not?
I would appreciate a response from Nokia considering that they wrote a PUBLIC document on CMetadataUtility class.

Just waking up this thread

Also interested in knowing if the CMetaDataUtility class is available in the S60 3rd edition SDK?

Or is it included in a SDK update?

Thanks for any info.

As far as I know that class is still missing...
I wonder why months ago Nokia has released through its forum a document describing a feature not available to third parties??

Hi,

metadata can be accessed on all s60 devices starting from 2.0 via the MMdaAudioPlayerCallback interface implementing class. To retrieve metadata after the audio file has been successfully opened, do the following (note that in the below example i just go after the album metadata):



// Get number of metadata
TInt metaCount = 0;
TInt error = iMdaAudioPlayerUtility->GetNumberOfMetaDataEntries( metaCount );
LOGSTRING2( "number of meta data entries: %i, ERROR was %i", metaCount, error );
CMMFMetaDataEntry* metaData = NULL;
// handle errors
if ( error!=KErrNone )
{
LOGSTRING1( "*** ERROR *** metadata count returned %i -> bail out early", error );
return;
}

while ( (metaCount--) > 0 )
{
LOGSTRING1( "looking at metadata entry #%i", metaCount );
// retrieve metadata
TRAPD( trapErr, metaData = iMdaAudioPlayerUtility->GetMetaDataEntryL( metaCount ) );
if ( !metaData || trapErr )
{
LOGSTRING1( "*** ERROR *** metadata retrieval failed, trapErr=%i", trapErr );
}
else if ( !metaData->Name().CompareF( KAlbumTag ) ) // "album"
{
LOGSTRING1( "album meta data found at #%i", metaCount );
iAudioInfo.SetAlbumName( metaData->Value() );
LOGSTRING1( "iAlbumName = %S", &iAudioInfo.AlbumName() );
}
else
{
// Pass.
LOGSTRING1( "metadata entry #%i not used -> PASS", metaCount );
}
delete metaData;
metaData = NULL;
}

Unfortunately the Metadata Utility API was not included in the S60 3rd Edition SDK despite initial plans to do so. The document mentioned above will be updated to reflect the current reality.

We are apologizing for creating this confusion.

I perfectly aware that Nokia Engineers can not spend full time answering questions on these forums BUT 10 months to have an official reply it seems a little too much.

Is possible to use this CMetaDataUtility API although is not released on the SDK. Are their libraries available on the target? Any information?

[Paul.Todd]

This library is avaliable in the extension plugin SDK

Please note the licence agreements in it.

I would recommend however following veskut's suggestion as this works in the emulator and on UIQ devices.

Thank you for your information .
