Description
QVideoFrame::toImage() is crashing on qt_convert_NV12_to_ARGB32() call
I see such crashes among users crash reports on AppCenter.
It's never reproduced for me locally, probably it happens with some specific video files.
Stack trace:

Seems it doesn't depend on mac model or macOS version, see Environment.
