Method: Zencodable::Encoder::Job#thumbnails

Defined in:
lib/zencodable.rb

#thumbnails ⇒ Object

ZC gives thumbnails for each output file format, but gives them the same name and overwrites them at the same S3 location. So if we have f formats, and ask for x thumbnails, we get x*f files described in the details API, but there are actually only x on the S3 server. So, the inject() here is done to pare that down to unique URLs, and give us the cols/vals that paperclip in VideoThumbnail is going to want
