      Description

      The following application will correctly play an H264 UDP video stream sent to localhost:5000 on 5.14 but the video never shows on 5.15

      import QtQuick 2.12
      import QtQuick.Window 2.12
      import QtMultimedia 5.12
      
      Window {
          visible: true
          width: 640
          height: 480
          title: qsTr("UDP Video Receiver")
      
          Video {
              id: video
              anchors.fill: parent
              fillMode: Image.PreserveAspectFit
              source: "gst-pipeline: udpsrc port=5000 ! application/x-rtp,payload=96 ! rtph264depay ! avdec_h264 ! qtvideosink"
              autoLoad: false
          }
      
          Component.onCompleted: {
              video.play()
          }
      }
      

      Using 'autoPlay: false' instead of 'autoLoad: false' makes it work in 5.15 as well but this is a regression to prior behavior.
