OEmbed Liquid Tag for Jekyll

OEmbed Liquid Tag for Jekyll

This is a simple liquid tag that helps to easily embed images, videos or slides from OEmbed enabled providers. It uses Magnus Holm's great oembed gem which connects to the OEmbed endpoint of the link's provider and retrieves the HTML code to embed the content properly (i.e. an in-place YouTube player, Image tag for Flickr, in-place slideshare viewer etc.). By default it supports the following OEmbed providers (but can fallback to Embed.ly or OoEmbed for other providers):

  • Youtube
  • Flickr
  • Viddler
  • Qik
  • Revision3
  • Hulu
  • Vimeo
