Direct Facebook Live streaming from mobile third-party apps is no longer reliably supported by Facebook/Meta. The most reliable method is to use a re-streaming service as an intermediary.
Recommended approach — use Restream or Castr:
- Create a free account at Restream.io or Castr.io
- Connect your Facebook account to the re-streaming service
- Get the RTMP URL and Stream Key from Restream/Castr
- In ScoreCam: Settings -> Live Streaming -> Add Account -> select “Other Service”
- Enter the Restream/Castr RTMP URL and Stream Key
- Start streaming in ScoreCam — Restream/Castr will forward the stream to Facebook Live automatically
It can be complicated so be sure to do lots of testing before a live event. Here is some additional documentation on live streaming: ScoreCam: Live Streaming
