XAVS2(1)

✨ XAVS2 ✨

okay so bestie, meet xavs2 — your new fave AVS2 (IEEE 1857.4) encoder 💖 that's it, that's the whole name section, she's a simple queen.

🌸 DESCRIPTION 🌸

xavs2</p purple> lib loaded: version 1.3.0 unstable 8-bit

no literally that's the description. iconic minimalism. 💅

🦋 SYNOPSIS 🦋

xavs2 [-f EncoderFile.cfg] [-p ParameterName=Value]
[--ParameterName=value]

so you can either hand her a config file with -f, or whisper individual params at her with -p ParameterName=Value or the fancy --ParameterName=value style. she speaks both dialects, no cap. 🫶

bestie that was seventy-six parameters and you read all of them?? main character energy fr fr 👑

and that's the whole page babes 🎀 this was xavs2 version 1.3, brought to you back in April 2021 — go encode something gorgeous and hydrate while you do it 💖✨🦋
