I have moved this into its own topic, as its facebook promotion not facebook login.
If you are in developer mode on your facebook application you will actually be able to use the function on your account that you dont have permission for. That is done so that you can test it, and indeed create a video to send over to facebook.
With the documentation for that, I do understand its outdated at present, however the reality here is we are documenting facebook functions, not our own functions. You would see the relevant docs on facebook if needed. I do have this on a list to update however. They do unfortunately change the functionality quite often
