To setup a Twitter live video feed, simply follow the below steps.
Simply head to the Stream Targets tab and hit the Create New Stream Target button.
You can then give your stream target a name and choose where you wish to send your broadcast.
To broadcast via Periscope, you must first create an account here – https://www.periscope.tv/account/producer
Once registered and configured, simply populate the information as required.
You can also select the source stream – by default this will be set to only stream any live video that you are sending to your video server (such as via OBS or any other encoding software). However, you can change this to constantly send your video source including any scheduled playlists, if you wish.
