Using Gstreamer



  • Hello,

    I would like to test the new gst-pipeline.

    I tried a simple qml as described in MediaPlayer.

    import QtQuick 2.15
    import QtQuick.Window 2.15
    import QtMultimedia 5.15
    
    Window {
        width: 640
        height: 480
        visible: true
        title: qsTr("Hello World")
    
        Item {
            anchors.fill: parent
    
            MediaPlayer {
                id: mediaplayer
                source: "gst-pipeline: videotestsrc ! qtvideosinks"
                onError: {
                    console.log(errorString);
                }
            }
    
            VideoOutput {
                anchors.fill: parent
                source: mediaplayer
            }
        }
    }
    

    I tried for both kits :

    • Desktop Qt 5.15.1 clang 64bit
    • Qt 5.15.1 for iOS Simulator

    And I get the same error :

    qml: Failed to load media
    

    Did I miss something ?
    Thanks

    Hi,

    From the looks of it you are trying to run that on macOS and iOS so it will not work. GStreamer is the backend for Linux.

    Therefore, unless you built GStreamer and the corresponding plugin for your platform, you will not be able to use these custom pipelines.
