Can't get QMediaPlayer frame rate

smab

hi,
ive tried to get the frame rate from a video by getting the metaData "VideoFrameRate".
It isn't working as the default value (0) is returned.

I printed the whole metaDataList with all available MetaData, and VideoFramerate isn't on that list.

I checked with MediaInfo and my video has a constant framerate. I tried to delete the audio that had a different framerate but it didn't change anything.

I am on Ubuntu 20.04 using Qt version 5.12.8 and QMake version 3.1.

I don't know if there are other ways to get the framerate but i'd appreciate some help ;)
