Usage

JavaScript/TypeScript

import { generateThumbnail, getThumbnailDataUrl } from 'tauri-plugin-video-thumbnail-api'

// Generate thumbnail as base64
const result = await generateThumbnail({
  source: 'https://example.com/video.mp4',
  size: 'medium' // 'small' (32x32), 'medium' (64x64), 'large' (128x128)
})

// Use in an img element
const imgElement = document.createElement('img')
imgElement.src = `data:image/png;base64,${result.base64}`

// Or use the convenience function
const dataUrl = await getThumbnailDataUrl('https://example.com/video.mp4')
imgElement.src = dataUrl

// Save thumbnail to file
const saved = await generateThumbnail({
  source: '/path/to/local/video.mp4',
  size: { custom: { width: 200, height: 150 } },
  outputPath: '/path/to/thumbnail.png'
})
console.log(`Saved to: ${saved.path}`)

Rust

use tauri_plugin_video_thumbnail::{VideoThumbnailExt, ThumbnailRequest, ThumbnailSize};

// In a command or elsewhere with access to AppHandle
let result = app.video_thumbnail()
    .generate_thumbnail(ThumbnailRequest {
        source: "https://example.com/video.mp4".to_string(),
        size: Some(ThumbnailSize::Medium),
        output_path: None,
