Video Thumbnail Generator
Quick Start
import ThumbnailGenerator from "@conpagoaus/video-thumbnail-generator";
// const ThumbnailGenerator = require('@conpagoaus/video-thumbnail-generator').default;
const tg = new ThumbnailGenerator({
sourcePath: "/tmp/test.mp4",
thumbnailPath: "/tmp/",
tmpDir: "/some/writeable/directory", //only required if you can't write to /tmp/ and you need to generate gifs
});
const thumbs = await tg.generate();
console.log(thumbs);
// [ 'test-thumbnail-320x240-0001.png',
// 'test-thumbnail-320x240-0002.png',
// 'test-thumbnail-320x240-0003.png',
// 'test-thumbnail-320x240-0004.png',
// 'test-thumbnail-320x240-0005.png',
// 'test-thumbnail-320x240-0006.png',
// 'test-thumbnail-320x240-0007.png',
// 'test-thumbnail-320x240-0008.png',
// 'test-thumbnail-320x240-0009.png',
// 'test-thumbnail-320x240-0010.png' ]
const thumbPath = await tg.generateOneByPercent(90);
console.log(thumbPath);
// 'test-thumbnail-320x240-0001.png'
const thumbPath = await tg.generateGif();
console.log(thumbPath);
// '/full/path/to/video-1493133602092.gif'
Options
There are options that can be passed when generating thumbnails. Both ThumbnailGenerate.generate(opts)
and ThumbnailGenerate.generateOneByPercent(number, opts)
can take options. See example below to get screenshots at a resolution of 200x200:
When generating screenshots/thumbnails
const thumbs = await tg.generate({
size: "200x200",
});
console.log(thumbs);
// [ 'test-thumbnail-200x200-0001.png',
// 'test-thumbnail-200x200-0002.png',
// 'test-thumbnail-200x200-0003.png',
// 'test-thumbnail-200x200-0004.png',
// 'test-thumbnail-200x200-0005.png',
// 'test-thumbnail-200x200-0006.png',
// 'test-thumbnail-200x200-0007.png',
// 'test-thumbnail-200x200-0008.png',
// 'test-thumbnail-200x200-0009.png',
// 'test-thumbnail-200x200-0010.png' ]
The opts
above can take anything that options in fluent-ffmpeg's Screenshots allow
When generating gifs
await tg.generateGif({
fps: 0.75, //how many frames per second you want in your gif
scale: 180, //the smaller the number, the smaller the thumbnail
speedMultiple: 4, //this is 4x speed
deletePalette: true, //to delete the palettefile that was generated to create the gif once gif is created
});
