Qml VideoOutput doesn't work after setting source to null once

[theonlylawislove]

import QtQuick 2.7
import QtQuick.Controls 2.0
import QtMultimedia 5.8

ApplicationWindow {
    visible: true
    width: 640
    height: 480

    property bool flip: true

    Timer {
        interval: 5000
        running: true
        repeat: true
        onTriggered: {
            flip = !flip
            if(flip) {
                videoOutput.source = null
            } else {
                videoOutput.source = player
            }
        }
    }

    VideoOutput {
        id: videoOutput
        anchors.fill: parent
        source: player
    }

    MediaPlayer {
        id: player
        source: "file://video.mp4"
        autoPlay: true
        loops:  MediaPlayer.Infinite
    }
}

After a few a trigger of Timer that sets videoOutput.source to null, it will never work again. The VideoOutput will just have a stale painting of a previously decoded frame, and will never change.

Any update on this?

I think I'm running into the same issue. This problem seems to be present on Linux, but not on Windows.

Why not change the source on the MediaPlayer rather than the VideoOuput?

That works thanks.

@lplessard I feel like I have closure now. ;-)
