trying to upload video using graph api - facebook-graph-api

Question

I have been trying to implement a video upload facebook feature for my mobile app for a while now but never really succeeded with rest. I learnt yesterday that the graph alternative was available.
After getting a few errors to do with access key mainly i have gotten to the point where output stream succesfully writes the movie file and the input stream just receives an empty json array once i have written the 3gp file.
Anyone any idea why I would get an empty json array and no video gets published when i get all my code to run, i get 200 response code and the server sends me a non error response?
Any help greatly appreciated.
Here is the class that gets the blank json array (send method). I have appended the token to the url and in the table to be sure. I am sorry if the code is untidy buts it just been a day of trial and error.

Answer 1

Are you trying to upload to a user's feed or to a page? There is an Open Bug regarding posting to pages.
Also, could you post some code?
Assuming that you've read the documentation:
Facebook Graph API->Video
And that you are using graph-video.facebook.com, not graph.facebook.com.
