Video Upload with cURL

Hi all,
I know this is Video Player forum, but couldn't find any forum related to Yahoo Video.

What I need is simple, I want to make a POST to Yahoo Video using

CODE

enctype="multipart/form-data"

and send a video file together with metadata (title, description, language, etc.)

What I miss is the url to send the POST to, i.e.

CODE

action="don't-know-this"

I looked for an API but couldn't find there. The original Yahoo Video Upload form uses a flash uploader and I couldn't find where it is sending the file data to.

I'd appreciate any help.

Thanks,
Majid
