Qt -- How to play audio files stored in QByteArray?

I am working on a special application in Qt that stores its .mp3 audio files in a QSQLITE database as BLOB data.

With the following code I create a QByteArray:

QByteArray array = query->value(0).toByteArray();

Then I try to play the sound with a QMediaPlayer:

mediaPlayer.setMedia(   QMediaContent(   QUrl::fromEncoded(array)   )   );
mediaPlayer.play();

But I unfortunately get this error: 

DirectShowPlayerService::doSetUrlSource: Unresolved error code 800c000d

The main thing that I would like to achieve is to be able to play these .mp3 files that are stored in the QByteArray.

Note: Storing the pathway only in the database is not possible in that special circumstance.

I would really-very appreciate your help. Thank you very much!

You need to provide the QByteArray as a QIODevice to the stream parameter of QMediaPlayer::setMedia(const QMediaContent & media, QIODevice * stream = 0).

Try the following:

QBuffer mediaStream(&array);
mediaPlayer.setMedia(QMediaContent(), &buffer);
mediaPlayer.play();
