Description of your issue, suggested solution and other information

Twitch.tv now records the (text) chat alongside videos. I would like to be able to download a video and have the chat as some form of associated download - maybe subtitles or other annotations. A couple of examples:

https://www.twitch.tv/cookingfornoobs/v/83226931 - a short clip (made by the broadcaster; clips made by viewers don't have associated chat)
https://www.twitch.tv/lilbumblebear/v/109190561 - a full-length VOD (will eventually expire, presumably making this a dead link)

Chat emotes might be a bit problematic. I'm okay with them being included either way - in their textual form ("noobsLove"), or as links (https://static-cdn.jtvnw.net/emoticons/v1/109023/1.0).

Wow! You are FAST! Thank you!

Emotes come out in their text form ("noobsLove") and in a mapping {"77681":[[0,9]]}. I've no idea what that part means, but I can run with the text. Much appreciated!

So how do I get the chat now? I'm totally confused. When I download a Twitch VoD there is no chat to be found and there's no reference to any option in the README either.

@Gorrrg Chat messages are available as subtitles. See https://github.com/rg3/youtube-dl/blob/master/README.md#subtitle-options

[Gorrrg]

Ah, I tried that out. But it seems it only download the first few messages. I remember something about the Twitch API only offering 5 second chunks of chat messages per request.

EDIT: it's a 30 second window https://discuss.dev.twitch.tv/t/getting-chat-replay-transcript/5295

Could you open a new issue for incomplete messages?

[Gorrrg]

Yep, I will.
