I can obtain a Facebook stream key through the graph API.
I saw there's an option to make the Facebook stream key persistent with updating the video ID persistent_stream_key_status but when I used this option, I got the following error:
No permission to use persistent stream key param
The Facebook permission that I used is publish_video for publishing videos directly to the user page.
I don't know what permission Facebook has to add a persistent stream key parameter. Does anyone know?
