We have an Apple iOS application which uploads video to Facebook. One the corresponding Facebook app side, we have asked our users to set it's privacy to public, to encourage sharing.
It has been working fine until around two weeks ago, the uploaded video can only be seen by friends only, if the user has set the default privacy to friends. It says:
"Control Your Default Privacy This setting will apply to status updates and photos you post to your profile from a Facebook app that doesn't have the inline audience selector, like Facebook for Blackberry."
I checked the Facebook graph API doc and did quite some search, and couldn't find a way to set the privacy setting of the video.
