Answer 1

Using the Addressable gem, you can save yourself some work. There's also a URI module in stdlib, but Addressable is more powerful.

require 'addressable/uri'

uri = Addressable::URI.parse(youtube_url)
if uri.path == "/watch"
  uri.query_values["v"] if uri.query_values
else
  uri.path
end

EDIT | Removed madness. Didn't notice Addressable provides #query_values already.
