Note. if url image in vtt file has only path like 160p-00001.jpg, you can set baseUrl here.

import {ThumbnailPreviewConfig} from 'react-native-thumbnail-preview';

useEffect(() => {
  //  setup RNFetchBlob for caching image
  ThumbnailPreviewConfig.initCacheImage(RNFetchBlob);
  // download and cache image before display thumbnail while seeking
  ThumbnailPreviewConfig.preFetchVttImage(vttUrl, baseUrl + '/');
  return () => {
    // clear cache image
    ThumbnailPreviewConfig.removeCacheImage();
  };
}, []);
