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.
