Earlier this year, Facebook launched an embedded video player. To ease integration between the player and third party websites, Facebook has now announced API access to the player. In addition to the API, Facebook now supports the oEmbed open standard, which simplifies embedding Facebook material.
The internet is full of videos that teach how to use complex software, like Photoshop or Final Cut Pro. Why not use the same technique for teaching how to use an API? Younger developers, who grew up in the age of these video tutorials, find this format especially useful. These types of videos do not have to have high production costs – they simply require screen capture and voice-over.
