    Hello, I'm trying to play videos within qt 5.14, using QMediaPlayer, however I'm encountering the following two errors (multiple times):

    1. QWidget::paintEngine: Should no longer be called

    2. ** CRITICAL **: 17:27:45.769: gst_vaapi_window_reconfigure: assertion 'GST_VAAPI_IS_WINDOW (window)' failed

    I've tried to install gstreamer-1.0 and all of its plugins but it's not working either. As I searched, it looks like it's an open bug (?), but I wonder if there could be any workaround. I'm using ubuntu 19.10, BTW.

    Thanks!

      Hi and welcome to devnet,

      One test to do is build your application with your distribution provided Qt.

        @SGaist Hi, Thanks for your reply.
        I tried also to play a video with one of Qt Creator's built-in examples (player example), but still, it's not playing the video correctly and give me exactly the same errors. It's just show a black screen and nothing more.
        I can't find my Ubuntu's Qt, do you know maybe where to find it (preferred using Qt creator).
        Thanks again!

          Hi
          When we say try Ubuntu's Qt we mean
          apt-get install qt5-default
          or similar versus installing a version from Qts site.
