Can you please explain what you meant by "this does not seem to be working"?
What issues were you experiencing?
You can upload any file type to Cloudinary, not just images. All non-images files, included video files are handled as 'raw' files.
Here's an upload example of a WMV file to your Cloudinary account:
Cloudinary::Uploader.upload("sample_video.wmv", :public_id => "sample_video", :resource_type => :raw)
For delivery, the returned public ID of the upload API call should be used.
Here's a URL example , notice the '.../raw/upload...' :
http://res.cloudinary.com/demo/raw/upload/sample_video.wmv
