QMediaPlayer in 5.15.0 not working

Hello, 

I'm here to report the bug about QMediaPlayer with a simple example

QMediaPlayer *mediaPlayer  { new QMediaPlayer } ;
mediaPlayer->setMedia(QUrl(currentMediaFileName));
mediaPlayer->setVolume(50);
mediaPlayer->play();

Error show:

Segmentation Fault 

And the example "Media Player Example" not working too in windows 10 & Qt creator 4.13.0. 

Error show:

DirectShowPlayerService::doRender: Unresolved error code 0x80040266 ()
