OvenLiveKit-Web VS Project-Lightspeed

I had great luck with setting up OvenMediaEngine with a custom OvenLiveKit player HTML. I stream to the server via RTMP and it publishes the stream over WebRTC. In the best case I got around 1 second latency, since there's a bit of overhead while converting audio channels (WebRTC only supports Opus, OBS only supports AAC (I think)). Also you can't use B-Frames, so you need to pay attention to that in OBS.

We also set WebRTC as input and output by applying OvenLiveKit for Web, which can send media stream to OvenMediaEngine's WebRTC Provider to direct broadcasting using a webcam/microphone on the desktop rather than an encoder as OvenStreamEncoder, OBS, or XSplit. Well, If you are interested in OvenLiveKit for Web, click HERE for more information.

Depending on how you want to achieve this, you could use a combination of OBS + Restreamer or OBS + Project-Lightspeed. Another solution would be to use more specific solutions like neko

I also used to use Project-Lightspeed, which worked great. I abandoned it because I wanted to get off of FTL based on the OBS thread above. It otherwise worked for me.

https://github.com/GRVYDEV/Project-Lightspeed is a 'Twitch like' server that does FTL input from OBS. You can run OBS on the Ubuntu desktop and do a desktop capture. Viewers can then watch on the 'Project Lightspeed' host.

I recommend Project-Lightspeed for this. It uses the FTL protocol (similar to the now defunct Mixer) with WebRTC for great latency. I've used it many times for streaming games, etc. and it works well.

Special thanks to the Ryujinx Discord for helping me test and to the Lightspeed Project (https://github.com/GRVYDEV/Project-Lightspeed)!

jellyfin can certainly do what you are looking for, but it seems like you probably don't have enough bandwidth to reliably host the service at home, and may be overkill for your usage... you could set up project lightspeed (https://github.com/GRVYDEV/Project-Lightspeed) on a $5/month VPS and use OBS to stream video with sub 1 second latency, you can install teamspeak or mumble or something on the same VPS for voice chat.
