Video.js plugin to display preview image of a video at the point of time when hovering on progress bar
$3
Simple as previous usage. Just import the module as you want, but you should load module first, so that the plugin can access previously instantiated global videojs module reference. Also, **you should import video.js module as a name of videojs, as the plugin will assume the name of imported video.js module as videojs.`js
import videojs from 'video.js';
import 'videojs-thumbnail-sprite';const player = videojs('video-id');
player.thumbnailSprite({
sprites: [
{
url: 'https://example.com/video.png',
start: 0,
duration: 10,
interval: 2,
width: 160,
height: 90,
},
],
});
`$3
There is only single property provided currently: js
const options = {
sprites: [
{
url: 'https://example.com/video-1.png',
start: 0,
duration: 10,
interval: 2,
width: 160,
height: 90,
},
{
url: 'https://example.com/video-2.png',
start: 10,
duration: 20,
interval: 2,
width: 160,
height: 90,
},
]
}
`|Option name|Datatype|Default value|Description|
|--------|------------|----|----|
|
|string|''|URL of thumbnail sprite image
|start|number|0|Start point of time of the video section that this sprite image is covering
|duration|number|0|Duration of the video section that this sprite image is covering
|width|number|0|Width of preview thumbnail (px)
|height|number|0|Height of preview thumbnail (px)
|interval|number|0|Interval between each preview thumbnails of the video section that this sprite image is coveringYou can use multiple sprite images in case that preview thumbnails for entire video is divided into several chunks. Just pass them as array of sprites, and the module will handle it on behalf of you.

To make things happen preperly, there are some rules to follow:1. Each
duration of video sections should not overlap each other. For example, if your first sprite image covers [0:00 ~ 10:00] and your second sprite image covers [5:00 ~ 15:00], then there is an overlap between them([5:00 ~ 10:00]). The module will emit warning on browser console if it catches any overlaps.
2. width and height should be provided for each sprites. If not, even if the images are loaded those will not be displayed as expected.
3. duration should be multiple of interval. From start point of time, at every interval` seconds, the preview thumbnail will be displayed, so to display corresponding preview with hovering time correctly, follow this rule.
