Videojs Quality Selector

The Nuevo plugin features a built-in option to switch between videos encoded with different resolutions.
You can setup multiple-quality videos in two different ways: by video resolution or by a simple choice between SD and HD quality. For both, you can set the default video quality to play first.

Video quality resolution

Code snippet

<video id="example_video_1" class="video-js" controls preload="auto" width="640" height="360" poster="//domain.com/path/to/poster.jpg">
<source src="//www.domain.com/path/to/video_240p.mp4" type="video/mp4" res="240" label="240p" />
<source src="//www.domain.com/path/to/video_360p.mp4" type="video/mp4" res="360" label="360p" />
<source src="//www.domain.com/path/to/video_480p.mp4" type="video/mp4" res="480" default label="480p"/>
<source src="//www.domain.com/path/to/video_720p.mp4" type="video/mp4" res="720" label="720p"/>
</video>

Video quality by SD/HD quality

Code snippet

<video id="example_video_1" class="video-js" controls preload="auto" width="640" height="360" poster="//domain.com/path/to/poster.jpg">
<source src="//www.domain.com/path/to/video_hd.mp4" type="video/mp4" res="HD" label="HD" />
<source src="//www.domain.com/path/to/video_sd.mp4" type="video/mp4" default res="SD" label="SD" />
</video>

If you prefer to show the qualities menu in the settings menu instead of a separate qualities menu, you can enable the dedicated qualityMenu Nuevo plugin option.

Code snippet

var player = videojs("my_player");
player.nuevo({qualityMenu: true});

The Nuevo plugin fires a resolutionchange event whenever the user switches the video quality manually. You can set a unique ID for your video to identify certain video and resolution that the user might have changed.

Code snippet

var player = videojs("my_player");
player.nuevo({video_id: "v-001"});
player.on('resolutionchange', function(event, data){
var video_id = data.id;
var resolution = data.res;
});

For HLS and DASH adaptive streams, resolution qualities are detected automatically based on the HLS playlist media specification.
Examples: HLS steaming test, Mpeg/Dash streaming Test.

The quality selector for HLS or MPEG/DASH allows you to set static quality or resolution and switch it back to auto selection. The quality selector will detect duplicated quality entries, showing both, resolution and bitrate when resolution is duplicated, but different bitrate, showing qualities by bitrate if resolution is missing for one of the .m3u8 or .mpd entries.
By default, each quality item in the qualities menu shows both resolution and bitrate values, if only both are provided in the m3u8 or mpd playlist. The Nuevo plugin's option resOnly allows you to hide bitrate values and leave only resolution values for display, e.g.

Code snippet

player.nuevo({resOnly: true});
