Allows you to download subtitles from Netflix
< Feedback on Netflix - subtitle downloader
Sounds like they are in image format, not as text. No plans to support them since you need some OCR program and I don't know how to get timestamps for them. Not mentioning that you'd have to play whole video to get them all.
Oh, and in my country there are no subs in image format so I can't add support to something I can't test. Tried some proxy but Netflix detects it.
That's when you download it for offline watching on mobile app. In browser it loads what seems to be master.idx (starts with midx) and segment.idx (starts with sidx) and then PNG files. If you know how to read those idx files, let me know.
