QVideoFrame bits error

I wrote a simple VideoSureface example similar to https://github.com/qt/qtmultimedia/blob/5.11/examples/multimediawidgets/customvideosurface/customvideowidget/videowidgetsurface.cpp using Pyside2.

And I have this traceback in Python:

TypeError: 'PySide2.QtGui.QImage' called with wrong argument types:
PySide2.QtGui.QImage(int, int, int, int, PySide2.QtGui.QImage.Format)
Supported signatures:
PySide2.QtGui.QImage()
PySide2.QtGui.QImage(PySide2.QtCore.QString, int, int, PySide2.QtGui.QImage.Format)
PySide2.QtGui.QImage(PySide2.QtCore.QString, int, int, int, PySide2.QtGui.QImage.Format)
PySide2.QtGui.QImage(PySide2.QtGui.QImage)
PySide2.QtGui.QImage(PySide2.QtCore.QSize, PySide2.QtGui.QImage.Format)
PySide2.QtGui.QImage(unicode, bytes = nullptr)
PySide2.QtGui.QImage(char[])
PySide2.QtGui.QImage(int, int, PySide2.QtGui.QImage.Format)
PySide2.QtGui.QImage(PySide2.QtCore.uchar, int, int, PySide2.QtGui.QImage.Format, QImageCleanupFunction = nullptr, void = nullptr)
PySide2.QtGui.QImage(PySide2.QtCore.uchar, int, int, int, PySide2.QtGui.QImage.Format, QImageCleanupFunction = nullptr, void = nullptr)

But in docs PySide2.QtMultimedia.QVideoFrame.bits() return type: PySide2.QtCore.uchar

And when created QImage class PySide2.QtGui.QImage(data, width, height, bytesPerLine, format[,cleanupFunction=nullptr[, cleanupInfo=nullptr]])
and get data - PySide2.QtCore.uchar

When I try use a Qimage created from current video frame, get segfault in my program.

Maybe I'm not working correctly with QVideoFrame.bits() from a current video frame?! How I can create QImage from QVideoFrame?
