I am running a bash script using ubuntu server on arm64 that live streams video and audio to youtube, heres the script below

#! /bin/bash

VBR="8000k"
FPS="24"
QUAL="superfast"

YOUTUBE_URL="rtmp://a.rtmp.youtube.com/live2"
KEY="****"

VIDEO_SOURCE="/mnt/disk1/test/****"

AUDIO_SOURCE="****"

ffmpeg \
    -re -f lavfi -i "movie=filename=$VIDEO_SOURCE:loop=0, setpts=N/(FRAME_RATE*TB)" \
    -thread_queue_size 512 -i "$AUDIO_SOURCE" \
    -map 0:v:0 -map 1:a:0 \
    -map_metadata:g 1:g \
    -vcodec libx264 -pix_fmt yuv420p -preset $QUAL -r $FPS -g $(($FPS * 2)) -b:v $VBR \
    -acodec libmp3lame -ar 44100 -threads 4 -qscale:v 3 -b:a 320000 -bufsize 512k \
    -report -loglevel fatal -nostats  \
    -f flv "$YOUTUBE_URL/$KEY"

The stream works fine, however after a seemingly random period of time, I get a conversion failed error

first after 64 hours of streaming second after 12 hours of streaming third after 8 hours of streaming fourth after 112 hours

The server itsef is fine, cpu and memory usage are extremly low and there are no spikes

from what i can guess the error has something to do with libx264 judging by the error logs, although I do not really know. After some guidance on what to do try next. Here is the tail end of the ffmpeg log report
