How can I display a video in Slicer through PythonQt?

You can display animated gifs, and some videos using QVideo:

movie = qt.QMovie("c:/path/to/myvideo.gif")
label = qt.QLabel()
label.setMovie(movie)
label.show()
movie.start()

You can load and replay mkv videos (compressed with VP9 or AV1) as volume sequences in slice views using SlicerIGSIO extension.

You can probably display videos using slicer.qSlicerWebWidget(). It is a Chromium web browser window, so it has all the infrastructure to replay videos, but I’m not sure what codecs are installed.
