You can get your Playstation 4 set up to send to your Lightstream Gaming Project with the following steps:
Go to Settings
Select "Set up Internet Connection"
Choose the option that applies to your networking setup
Select "Do Not Specify"
Enter 18.104.22.168 (or 22.214.171.124 for European users)
Select "Do Not Use"
Save and you're all done!
Once you've done this you're all set to start broadcasting through the Twitch share integration and everything from your PS4 will send to your Gaming Project.
