### Description of your *issue*, suggested solution and other information

Downloading of subtitles (the chat) for Twitch videos fails.

[vxbinaca]

They're not subtitles. The extractor doesn't support chat. Same with youtube chat, and comments.

[ealgase]

It previously extracted chat from the rechat endpoint (which has been removed).

[zachary-D]

I'm having this same issue. Does anyone know of any fixes?

I think making the modifications in this PR might work - #15828 - but I haven't tried them yet

[ealgase]

You can use https://github.com/PetterKraabol/Twitch-Chat-Downloader/

[zachary-D]

Is there a way to tie that into youtube-dl?

[ealgase]

Not without scripting it yourself.

@remitamine Should this be closed after 4787f2658b7e4fc02a0980c6d2e94e7394fa8bea? I'm not really sure or I'd do it myself.

[vxbinaca]

rechat subtitles count as the text chat, I vote to close.

[za3k]

Come on mate, did you even read this issue, or just the title? This is rechat JSON failing to parse and ffmpeg erroring out.

Sorry, that was totally confusing! I opened a second bug with an almost identical title, and thought you were voting to close ten seconds after I opened it. I'm the bad reader here for sure! Thanks for your quick response >< My apologies.
