QVideoFrame::availableMetaData() is always empty

I have subclassed a
QAbstractVideoSurfaceand set it as output to a
QAbstractVideoSurface::present(QVideoFrame)function I require some information about the current frame being displayed. For this I would like to use
QVideoFrame::availableMetaData(), but it is always empty. This meta data contains useful information for a frame like when it should be displayed...is it a I, P or B frame etc.
I tried several files, coming from different sources and there is never meta data available in the frame. Is this a Qt bug? What am I doing wrong?
Sidenote: This is a more narrow question to my older question which it seems no one can answer: https://forum.qt.io/topic/106091/qvideoframe-does-not-deliver-correct-starttime-and-endtime-qmediaplayer-issue/4
