How to change the default quality of Youtube video transmission in VideoJS player?

Question

JavaScript

I installed a VideoJS player on my site . Installed streamer from youtube . Everything works fine, but by default the YouTube video comes in SD quality, i.e. 360. How can I change it to HD? Apparently, the desired parameter is stored somewhere in the vjs.youtube.js file. Here is an excerpt from this file;

videojs.Youtube.prototype.onPlaybackQualityChange = function (a) {
    switch (a) {
    case "medium":
        this.player_.videoWidth = 480;
        this.player_.videoHeight = 360;
        break;
    case "large":
        this.player_.videoWidth = 640;
        this.player_.videoHeight = 480;
        break;
    case "hd720":
        this.player_.videoWidth = 960;
        this.player_.videoHeight = 720;
        break;
    case "hd1080":
        this.player_.videoWidth = 1440;
        this.player_.videoHeight = 1080;
        break;
    case "highres":
        this.player_.videoWidth = 1920;
        this.player_.videoHeight = 1080;
        break;
    case "small":
        this.player_.videoWidth = 320;
        this.player_.videoHeight = 240;
        break;
    default:
        this.player_.videoWidth = 0, this.player_.videoHeight = 0
    }
    this.player_.trigger("ratechange")
};

this part of the code made me think that it is somehow possible to switch the default value.
But the line

this.player_.videoWidth = 0, this.player_.videoHeight = 0

definitely not responsible for this.

Player is pretty good, it has a lot of advantages, and you don't want to refuse it because of one little thing.
