How to download WatchTCM subtitles?

[perrymason]

TCM.com seems to use usual AES encrypted m3u8 .ts streams for videos but yt-dlp and n_m3u8dl-re show 0 subtitle stream when I download 720p layer6_bk m3u8 streams. I use Chrome DevTools to find .m3u8 links when I click the Play button.
I was thinking maybe there is some obscure subtitle stream format inside .ts files or it is more likely that a javascript downloads and plays subtitles?
Any ideas how to get to the bottom of this subtitles mystery?

use CCExtractor to extract subtitles

CCExtractor doesn't support m3u8 urls if I'm not mistaken. How should I use it?

[iamghost]

Download video then add cmd with ccextractor then it extract to srt

[perrymason]

It shows 0 subtitle streams, ffmpeg -i also shows 0 subtitle streams

iamghost, thank you so much. It seems the latest ccextractor has some issues on my old PC (crashes during analyzing), so I used the recommended 0.89 version compatible even with Windows XP and now it worked perfectly and extracted an .srt file.
