    I'm trying to run the QML Video Example on a custom iMX6ULL board. I have already installed gstreamer-1.0 as well as all the plugins.

    Running the gst-play-1.0 with an MP4 sample video works flawlessly; running the Qt Video Widget Example works too, but running the QML Video Example doesn't, in particular when starting the video the audio works but the screen remains black with the QML frame rate ranging between 23 and 28 fps.

    I also tested the GStreamer API and it works.

    Do you have any advice, because I really need to play video in a QML application?

      Seems like Qt devs are closing all the GStreamer related issues as "Won't Do". I believe they are going to introduce something for Linux.
      Let's be patient :-)

          Tickets are closed when they are not worked upon for a long time.

          So it's either what you say or (more likely) these GStreamer issues are completely abandoned.

          Sam, an example https://bugreports.qt.io/browse/QTBUG-42034 although it is not about GStreamer as such.

            @sierdzio thanks for the example, I think the resolution type is a bit misleading with regard to the reason the bug was closed.
