[PyQt] About pyuic and phonon widgets

[safa1996alfulaij at gmail.com]

Hello

I designed a window which have Phonon widget. When I tried to generate it by 
pyuic5 it gave me the error:
Unknown Qt widget: Phonon.VideoWidget
even if I used pyuic4.

Another thing, Where are the QMultimedia widgets in the designer? Like the 
QVideoWidget?!

Thanks in advance
