I very strongly recommend that you familiarize yourself with some OBS and DLive basics before continuing with this guide as it is not very OBS or DLive beginner friendly.

This guide assumes that you are wanting to broadcast your PS4 gameplay on DLive. Unfortunately, the live streaming capabilities of the PS4 are rather simple and very limited. A stand-alone PS4 cannot broadcast on DLive, is unable to play music in the stream, and cannot utilize those cool overlays that many PC streamers use. Fortunately, there is hope! With a decent computer, you can use Playstation Remote Play to stream your PS4 Gameplay onto your computer, and run the stream out of OBS instead!
