[QtQuick, Multimedia, GStreamer] Can't play video stream

0x5FB5

I've used QtQuick's Multimedia and VideoOutput objects and everything works good on Qt 5.12.x. On Qt 6.3.1 video doesn't playing and I have only one string in console: qt.multimedia.player: Unable to set the pipeline to the paused state.

Code:

import QtQuick 2.0
import QtMultimedia

Item
{
	id: root

    MediaPlayer {
        id: player
        source: "gst-pipeline: udpsrc port=10001 ! application/x-rtp, media=video, clock-rate=90000, encoding-name=H264, payload=96 ! rtph264depay ! decodebin ! autovideosink";
        videoOutput: video
    }

    VideoOutput {
        id: video
        anchors.fill: parent
        fillMode: VideoOutput.PreserveAspectCrop
    }

}

Hi,

The Qt Multimedia module has seen a big rewrite for Qt 6 and things like custom GStreamer pipeline have been removed.

If memory serves well, support for networked media stream should work out of the box.

@SGaist so, should it means that I need to change the pipeline or like that?

If memory serves well, you should use the URL for the stream directly.

Yes, it works!
For test I send a videotestsrc via console:
gst-launch-1.0 videotestsrc ! "video/x-raw,width=640,height=480" ! x264enc ! mpegtsmux name=mux ! udpsink host=127.0.0.1 port=8080

In QML:

...
    MediaPlayer {
        id: player
        source: "udp://@127.0.0.1:8080"
        videoOutput: video
    }

    VideoOutput {
        id: video
        anchors.fill: parent
        fillMode: VideoOutput.PreserveAspectCrop
    }

    Component.onCompleted:
    {
        player.play()
    }
