Shows a preview after launch:

But trying to play the video results in an error:

If change url to: "https://www.youtube.com/watch?v=cabBXCq7_P8"

import QtQuick
import QtQuick.Controls
import QtQuick.Window
import QtWebEngine

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")

    WebEngineView {
        id: webView
        anchors.fill: parent
        url: "https://www.youtube.com/watch?v=cabBXCq7_P8" //"https://www.youtube.com/embed/cabBXCq7_P8"
    }
}

We will receive a message: You browser can't play this video

Can anyone help me what the error is and how to fix it?
As a result, the video is expected to play
