Yahoo Video Upload with cURL

I want to use cURL to post a video to Yahoo Video. I planned to make two calls to yahoo as follows:

1. call to sign in to an existing account and store the returned cookie
2. call to send the cookie, collected video metadata (title, description, etc.), AND the file

But the problem is that apparently, the original Video Upload form sends the data in two calls. The obvious one is a POST which only sends the meta data. The file itself is handled by a flash uploader a开发者_如何学Pythonnd it is not clear where the data is sent and what is sent along with the file data itself.

Any idea where to look for answers?

It'll be interesting to see who responds to this, as there is no API that allows you to upload to Yahoo Video. See: http://developer.yahoo.com/everything.html#apis

If there's no API, you cannot do this no matter how much you'd like. When companies have proprietary technology for uploading content, it's typically for a reason, so that people cannot post content without them knowing where it originated (and thus making them incapable of tracking inappropriate use).
