FFMPEG to convert ISO files to m3u8

Hi, We are looking for someone who can provide us FFMPEG script. We would like to convert ISO files to m3u8. Also, we would like to convert 2TB ISO files to m3u8 per day automatically with the script. If you can help us, I will send you our ISO sample files. By the way, we are using this script for now, but converted video is out of sync with the audio. ffmpeg -hide_banner -y -i [login to view URL] -vf scale=w=640:h=360:force_original_aspect_ratio=decrease -c:a aac -ar 48000 -c:v h264 -profile:v main -crf 20 -sc_threshold 0 -g 48 -keyint_min 48 -hls_time 4 -hls_playlist_type vod -b:v 800k -maxrate 856k -bufsize 1200k -b:a 96k -hls_segment_filename output/360p_%[login to view URL] output/[login to view URL] -vf scale=w=842:h=480:force_original_aspect_ratio=decrease -c:a aac -ar 48000 -c:v h264 -profile:v main -crf 20 -sc_threshold 0 -g 48 -keyint_min 48 -hls_time 4 -hls_playlist_type vod -b:v 1400k -maxrate 1498k -bufsize 2100k -b:a 128k -hls_segment_filename output/480p_%[login to view URL] output/[login to view URL] Thank you.
