VTT Subtitle from M3U8 Defaulting to 00:00:00 Timestamps for Each Line

[diegosalinas]

I am trying to extract a webvtt based subtitle file using ffmpeg.

This is the link for the subtitle m3u8:

[URL="https://content-aaps1.uplynk.com/multiple/9a497a6ee69441c69371499105effbcc,fe41a9a856744852a 914b400cda24dec,8cf14e3d244245f4addd5bbed48a343d/sub2.m3u8?pbs=f8ca72a034a04f52bb46fb161ba9ead3&mbt racks=1"]

This is the ffmpeg command I'm running:

ffmpeg.exe -i "https://content-aaps1.uplynk.com/multiple/9a497a6ee69441c69371499105effbcc,fe41a9a856744852a 914b400cda24dec,8cf14e3d244245f4addd5bbed48a343d/sub2.m3u8?pbs=f8ca72a034a04f52bb46fb161ba9ead3&mbt racks=1" testing.vtt

This is what the subtitles look like:

3
00:00:00,000 --> 00:00:02,976
Barcelona. Sunday 13th June 1982.

4
00:00:00,000 --> 00:00:02,000
The opening ceremony
of the 12th World Cup Finals.

464
00:00:00,768 --> 00:00:03,128
Rummenigge prepares
for action.

465
00:00:00,776 --> 00:00:02,536
Despite the defeat Spain
went through too.

871
00:00:03,760 --> 00:00:04,096
Inspired by Platini,
the French gain momentum.

872
00:00:03,760 --> 00:00:04,096
The Italian supporters
seem in the majority.

If I export to .srt using ffmpeg, it still doesn't work. The timestamps are incorrect and lines such as the one below appear throughout the subtitle.

"(whistle blowing) WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:24698880"

Any suggestions? This is my required video: https://www.fifa.com/fifaplus/en/watch/5FypRY9S1PYGQII87khD5x

Thanks for the link, I tried the different manifest (https://content-aapm1.uplynk.com/preplay2/9a497a6ee69441c69371499105effbcc,fe41a9a856744852a 914b400cda24dec,8cf14e3d244245f4addd5bbed48a343d/ee514abcce370609ce25b6801a7eb29f/6FkjbhzHnrp1ZMdXK5OqrZ6UBbKp83PEzLRGGJIuVz7a.m3u8? pbs=933b9d2c57454507959ecebc5d095026&mbtracks=1") but unfortunately the subtitle timestamps are all over the place in that case as well

What command did you use?
The yt-dlp command works.

[diegosalinas]

I used this:

yt-dlp "https://content-aaps1.uplynk.com/preplay2/9a497a6ee69441c69371499105effbcc,fe41a9a856744852a 914b400cda24dec,8cf14e3d244245f4addd5bbed48a343d/ee514abcce370609ce25b6801a7eb29f/4DXNq191N8gNAuUG0S3vr41DiGE7IZ2YQ2JJGuRkCNTw.m3u8? pbs=b530381fbeea4b38a9d96fee50af2ae8&mbtracks=1" --skip-download --write-subs

I've attached the files. Link to VTT: https://we.tl/t-ai0vEJfY05

hmmm, thats strange because i ran the same command with a fresh m3u8 link and it works for me.
