Attributes of an Audio Files

u2gilles

Hi, I would like retrieve information about mp3 files like "title" , "artist", "date creation" etc...
These attributes are not part of QFileInfo
Thanks for your help.

Hi,

You have to look at the multimedia module to get these informations

the keyword you are looking for is ID3 tags for mp3 files

Thanks SGalst, I just tried using multimedia module.
My mp3 file has a title and lots of properties but when i test isMetaDataAvailable() , it returns false and of course metaData("Title") does not return anything.
Am I using the wrong method and Class ? My goal is to retrieve existing properties , not to set mine.
Please find below an extract of the code :

@
player = new QMediaPlayer;
player->setMedia(QUrl::fromLocalFile("D:/Test1/deux.mp3"));
player->setVolume(50);
qDebug() << "meta:" << player->isMetaDataAvailable();
ui->lineTitre->setText(player->metaData("Title").toString());
@

Please note that the mp3 plays successfully below in my program :
@
void Widget::on_butStart_clicked()
{
player->play();

}

IIRC you have to start playing the file before you can access the metadata

It does not seem to be the case. I created a refresh button to use after starting playing but isMetaDataAvailable() still reply false.

Could you try the multimedia examples to see if they also suffer from the problem ?
