LiveU is excited to be part of the In Real Life community! A lot of members of this community use graphic overlays from systems such as Streamlabs, sometimes using open source software like the Open Broadcast Encoder to render those graphics into their stream.
There are several approaches to how to set this up, including a company that will assist you if you need it. Further information on all options is below.
RTMP Push Vs Pull
One core issue with this setup is RTMP Push vs Pull. Most encoders, LiveU Solo included, Push. The original model always had a server in the middle, in the original setup, Flash Media Live Server, but more commonly today Wowza Media Server or an open source option such as n*ginx with its RTMP module. This receives the push from an encoder, and offers it as Pull to players. Players that only support Pull cannot receive a stream directly from an encoder that does Push.
OBS (Open Broadcast Software) and many similar examples only do Pull. So to read your LiveU Solo stream using OBS or similar software, you need a server in the middle - either locally hosted (like on your own server or PC) or cloud hosted. There are many options for this, more than just the two mentioned above. This article won't cover the details of such a setup, which can range from quick and easy to quite complex depending on needs and hosting options. But, with this basis of information you should be able to find many guides to how to setup such a RTMP server online.
