m3u8 file / HLS definition


Hi sorry for too much question but I'm really confuse.

I go to https://developer.jwplayer.com/jw-player/demos/toolbox/hlsv4-audio-tracks/
to learn how to make JWplayer toggle menu Multi Audio Track

I download m3u8 example file from there.
open that file with texteditor, inside file look like this

#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio",LANGUAGE="eng",NAME="English",AUTOSELECT=YES,DEFAULT=NO,URI="en/prog_index.m3u8"
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio",LANGUAGE="fre",NAME="French",AUTOSELECT=YES,DEFAULT=NO,URI="fr/prog_index.m3u8"
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio",LANGUAGE="nl",NAME="Dutch",AUTOSELECT=YES,DEFAULT=NO,URI="nl/prog_index.m3u8"
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=150000,CODECS="avc1.42e00a,mp4a.40.2",AUDIO="audio",SUBTITLES="subs"

the question is what is URI="en/prog_index.m3u8 on the edge of each line? Is it just only a sound file or full video(animation+sound) file
now I have two video file 1. the animation with Thai audio 2.the same animation with Japanese audio. Do I need to separate "sound" and "animation" from each other?

another question : what is HLS definition? I read from many article. some article said it's streaming for IOS <<<This mean it cannot stream on desktop PC?
some article said HLS is just a playlist.

Hello,

I would think the M3U8 file would have to have the mutli-channel/ language feature embedded into the main manifest so that the player can properly pull in all of this content when loading the .ts segments. Looking at the manifest in terminal, the type/group parameters leads me to believe these are the audio only tracks.
