Getting up to 12 seconds of delay on LAN SRT stream.

[Gremious]

Subject of the issue

I connect my obs stream to restreamer via LAN (the streaming and server computer are one and the same) - and I get 7-12 seconds of delay.

I cannot get under 1 second delay, I've tried everything I could think of, and am looking for help.

Your environment

Obs Studio: 31.1.1 (64 bit)

My obs settings are as follows:

I also have the option to use the VAAPI h.264 on Ellesmere [GPU] video encoder, but I would not know what settings to put there.

Happy to provide any additional information.

Steps to reproduce

Running restreamer via docker.

Connect and change the network public domain this same computer's LAN IP, "192.168.1.200".

Enable SRT with port 6000 and Token: "token".

Create new channel -> SRT -> paste link into OBS streaming settings, press "Start Streaming"

Expected behavior

Sub second latency on the stream.

Actual behavior

Stream connects, but there is big delay despite being SRT.

Here's a video showcasing this: (sorry, no fancy timer, but me wiggling my mouse should be enough)

These core options help achieve low latency.
