Setup multiple resolution videos for quality selector
Nuevo plugin features a built-in option to switch between videos encoded with different resolution.You can setup multiple quality videos in two different ways: by video resolution or by 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>
Code snippet
var player = videojs("my_player");
player.nuevo({qualityMenu: true});
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 adaptive stream and live streaming resolution qualities are detected automically based on the HLS playlist media specification.
Examples: HLS steaming test, Live steaming test
Same concerns MPEG-Dash stream.
Example: Mpeg/Dash streaming Test
Quality selector for HLS and MPEG/DASH allows to set static quality/resolution and switch it back to auto selection. Quality selector is enough advanced to 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 m3u8 entries.
By default, each quality item in qualities menu shows both: resolution and bitrate values, if only both are provided in m3u8 or mpd playlist. On June 8th new option
resOnlywas added to Nuevo plugin v 11.2.0, so the user may order to hide bitrate values and leave only resolution values for display, e.g.
Code snippet
player.nuevo({resOnly: true});
