Question / Help NVENC settings for FFMPEG to decrease latency

[gdlr]

I followed this guide to udp stream with FFMPEG using nvenc encoding :
https://obsproject.com/forum/resources/obs-studio-send-an-udp-stream-to-a-second-pc-using-obs.455/

Problem is there is a latency of 500-1000 ms when displaying the stream on the same computer (i use ffplay.exe).
Is there any way to decrease it using nvenc / ffmpeg settings ?

I want to stream and play the video on another computer with a latency lower than 100 ms. Is there any way to do it with obs ?

You tried the NDI plugin yet?

I will give it a try . Thanks.

Does NDI work well when the second computer is not on LAN ?

 

[Harold]

No.

Any way to improve the latency on nvenc ?

I tried with mpeg2video encoder instead of NVENC and the delay decreased a bit. It's still not low enough though.

I found this post that might help , but i don't know what command line parameters for ffmpeg are already set by OBS.

That guy said these are settings for close to zero latency ffmpeg:
ffmpeg \
-f x11grab -s 1280x720 -framerate 30 -i :0.0 \
-c:v mpeg2video -q:v 20 -pix_fmt yuv420p -g 1 -threads 2 \
-f mpegts - | nc -l -p 9000

What should I type in OBS for "Video encoder settings (if any)" ?
