Qt Quick-realize video player based on QMediaPlayer

In Qt Quick, QMediaPlayer is a very useful class that can help us quickly implement a cross-platform video player. In this article, I'll describe how to use the QMediaPlayer class to implement a basic video player.

Implementation steps

Step 1: Create a QMediaPlayer instance

First, we need to create a QMediaPlayer instance in QML and set the corresponding properties:

import QtMultimedia 5.0

Rectangle {
    id: root
    width: 320
    height: 240

    MediaPlayer {
        id: mediaPlayer
        source: "movie.mp4"
        autoPlay: true
        width: parent.width
        height: parent.height
    }
}

In this example, we create a QMediaPlayer instance called "mediaPlayer" and set it to autoplay. We also set its source file to be "movie.mp4" and set its size to be the same as its parent object.

Step 2: Create a VideoOutput object

Next, we need to create a VideoOutput object in QML and associate it with the QMediaPlayer instance:

import QtQuick 2.0
import QtM
