Video player on ubuntu isn't working

[thomasons]

I wrote a simple video player in Qt :

import QtQuick 2.7
import QtQuick.Controls 2.0
import QtQuick.Layouts 1.0
import QtMultimedia 5.9
ApplicationWindow {
visible: true
 Video{
     id: video
     width: 800
     height: 600
     autoPlay: true
     source: "C:/Users/papu/apps/a.mp4"
 }
}

On Windows everything is working fine. When I run this code on Ubuntu I can only see a white background and I dont' have any errors or warnings. I tried with several paths like "/home/papu/a.mp4", "file:///home/papu/a.mp4" etc. Question is, is there a problem with the path or am I missing some drivers?

Best Regards!

Hi and welcome to devnet,

Which version of Qt are you using ?
Can you read that file with GStreamer directly ?
