friendbc.rb

require 'open-uri'
require 'json'

your_access_token = "put your access token from the Graph API Explorer here"
url = "https://graph.facebook.com/me/home?fields=from,picture,link,source,name,description,type&access_token=#{your_access_token}"

result = JSON.parse(open(url).read)

posts = result["data"]

posts.each do |p|
  if #something -- how will you test if the post is sharing a video?
    puts "#{p["from"]["name"]} said, '#{p["message"]}'"
    # print the link to video, for good measure
  end
end
