It is straightforward, as far as live stream setup goes. Here is a reference from Dacast as well.

On Dacast: open the Encoder Setup page and note your Server, Stream Key, Username, and Password.

In ScoreCam:

1. Go to Settings, Live Streaming, Live Stream Settings and tap Setup New Account (or tap the pencil icon on an existing account).
2. Set Name to Dacast.
3. Set Service Type to Other Service.
4. For Stream Link, use Dacast's Server value.
5. For Stream Key, use Dacast's Stream Key value.
6. For Username, use Dacast's Username value.
7. For Password, use Dacast's Password value.
8. For Authentication Type, choose Limelight (llnw).
9. Tap Save, then tap the new Dacast account in the list to select it.
