intro this part is a continuation of the previous post. In this post i will explain how to stream video with ffmpeg on a LAN, and keep the latency as low as possible. note: this post is for lan only, client and server need to be on the same network or wifi. (In detail: you need te be in the same layer 2 segement) this is because we use multicast udp to transport the video.

FFMPEG is a video and audio manipulation library and cli program. ffmpeg is the main tool ffplay is a simple graphical viewer. ffprobe will only probe input data (file, stream, … ) A short explanation how the ffmpeg cli accepts parameters: ffmpeg <globaloptins> <format> <inputfile_options> <input> <output_option> <output> show info the ffmpeg cli has alot of options, this will give you a good starting point to find info about them:

introduction Since my last endavour in low latency firewalling, a lot has happend in the linux networking world. New algorithms where developed that reduce manual configuration by a large factor. I use this setup at home to: keep gaming latency low keep voice call’s (teams, slack, discord, teamspeak) latency low even in the event that there is high upload (cloud sync, email with large attachment, video streaming, backup), response times for interactive traffic are low and usable.
