EDIT: I found the problem... QAbstractVideoSurface has been replaced by the QVideoSink class in Qt6:

EDIT2: I think i will open two different topic since I found different "bug?"

Hi there, I'm in the exact same boat as you. also

QMediaMetaData::Author

returns blank on Linux but works in Windows
Using Qt5.5.1... Been looking for a few days now for a solution with no luck too.

meta_player is my media player objext
Signal:
connect(meta_player, SIGNAL(metaDataChanged()), SLOT(metadata_capture()));

Code of capture:
if((meta_player->isMetaDataAvailable()) &&( inc < file_list.length()))
{
qDebug() << "Meta info available"<<endl;
QStringList list = meta_player->availableMetaData();
qDebug() << " Meta Data ="<<list.count()<<endl;
for(int i=0;i<list.count();i++){
qDebug() << list.at(i) << " = "<< meta_player->metaData(list.at(i)).toString();
}
qDebug()<<"**********************************************************************************";
inc++;
qDebug()<<"After Icrement "<<inc;
qDebug()<<"File Name"<<file_list.at(inc);
meta_player->setMedia(QUrl::fromLocalFile(file_list.at(inc)));
qDebug()<<"File Name"<<file_list.at(inc);
}

The Signal meta_player->setMedia(QUrl::fromLocalFile(file_list.at(inc))); is not emitted properly. For example when I add 6 songs i get met info for two songs. The result is ambiguous, its not constant.
