A plugin for clappr which will display thumbnails when hovering over the scrub bar. Thumbnails can either be individual images or a sprite sheet. You can find a tool which will generate a sprite sheet from a video here.
Add both Clappr and the thumbnails plugin scripts to your HTML:
<head>
<script type="text/javascript" src="http://cdn.clappr.io/latest/clappr.min.js"></script>
<script type="text/javascript" src="https://cdn.jsdelivr.net/clappr.thumbnails-plugin/latest/clappr-thumbnails-plugin.js"></script>
</head>
You can also find the project on npm: https://www.npmjs.com/package/clappr-thumbnails-plugin
Then just add ClapprThumbnailsPlugin into the list of plugins of your player instance, and the options for the plugin go in the scrubThumbnails property as shown below.
var player = new Clappr.Player({
source: "http://your.video/here.mp4",
plugins: {
core: [ClapprThumbnailsPlugin]
},
scrubThumbnails: {
backdropHeight: 64,
spotlightHeight: 84,
thumbs: [
{time: 0, url: "assets/thumbs/thumb_1.jpg"},
{time: 2, url: "assets/thumbs/thumb_2.jpg"},
{time: 4, url: "assets/thumbs/thumb_3.jpg"}
]
}
});
backdropHeight and spotlightHeight are the heights that the thumbnails will be scaled to for the backdrop and spotlight respectively. Either of these can be 0 or null to disable them. The thumbs property is an array of all the thumbnails. The time property is the time in seconds that maps to the thumbnail image located at url.
If you are using a sprite sheet you can use the helper method ClapprThumbnailsPlugin.buildSpriteConfig(spriteSheetUrl, numThumbs, thumbWidth, thumbHeight, numColumns, timeInterval) which will generate the object for the thumbs property for you.
You can add/remove thumbnails at any time using the addThumbnail() and removeThumbnail() methods as shown below. Both these methods will also take an array.
var thumbnailsPlugin = player.getPlugin("scrub-thumbnails");
var newThumb = {
url: "http://tjenkinson.me/clappr-thumbnails-plugin/assets/thumbnails/thumb_10.jpg",
time: 12.5
};
thumbnailsPlugin.addThumbnail(newThumb).then(function() {
console.log("Thumbnail added.");
}).then(function() {
thumbnailsPlugin.removeThumbnail(newThumb).then(function(success) {
console.log("Thumbnail removed.");
});
});
