uploading video in Facebook, ¿parameters?

I'm uploading a video to facebook form my iphone app. More customized is better. I would like to know how many parameters I can set in params, and what are them. but i'm not able to find it, any help?

This is the function:

[facebook_ requestWithGraphPath:@"me/videos"
                         andParams:params
                     andHttpMethod:@"POST"
                      开发者_如何学JAVA andDelegate:self];

I have "content type", "title", "description" and the video... anything else?
