2 Videos 1 MediaController

I wish to display 2 vide views side by side. I do not wish to implement custom MediaController because the default is very good, but, no matter what I did I could not control 2 videos simultaneously.

    val mediaController = MediaController(requireContext())
    mediaController.setAnchorView(videoViewF)
    videoViewF.setMediaController(mediaController)
    videoViewR.setMediaController(mediaController)

How can I achieve this? Can I get callback from MediaController or the first VideoView when progress is changed/paused/played? Or some other way?
