        Hi,

        Did you check that you have all sets of GStreamer plugins installed on your system ?

                Do you have more error information printed on the console when playing that video ?

                Can you play it with gstreamer directly ?

                  @SGaist Havn't tried but i think it will be ok as it works on qt 5.7.1. no just the errors mentioned above.
