So here it is an m3u8 file. I am trying to cut it and create a new clip let's say 15 seconds with the first two ts files and remove the others. This new clip will be in m3u8 format and will look like

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:13
#EXT-X-MEDIA-SEQUENCE:0
#EXTINF:12.960000,
https://d3s84sk2607r1u.cloudfront.net/video_866552260.ts
#EXTINF:2.040000,
https://d3s84sk2607r1u.cloudfront.net/video_866552261.ts
#EXT-X-ENDLIST

I am using node js and FFmpeg. So is there a way to create a small clip which will be a m3u8 file, from this m3u8 file. I am trying to create a script that will execute. So if it's not node js then any other like java or python will be helpful for me

I am trying to create a script.js that will run on my command like

node script.js start_time end_time ./path/file.m3u8

that will generate a new m3u8 file
