I set the playlist, but the lower right corner does not show the HD label.
But i found if i used the same type of three video format,then the HD label is show.

This is code:

var config = {
preload: 'auto',
"autostart": false,
width: "100%",
aspectratio: "16:9",

"playlist": [{
"image": "/February2015/avengers.jpg",
"sources": [{
"file": "/demo-site/videos/the-amazing-spiderman-2.ogv",
"label":"HD3"
},{
"file": "/demo-site/videos/avengers-age-of-ultron.mp4",
"label":"HD2"
},{
"file": "/demo-site/videos/the-amazing-spiderman-2.webm",
"label":"HD1"
}]
}],

tracks: [{
file: "/vtt/46.vtt",
kind: "thumbnails"
}],
"primary": "html5",
};

jwplayer('video_containers').setup(config);
