Age Restricted Youtube Video Support

[bencorryp]

Is it possible to allow the bot to search (and play) age-restricted content on youtube? Could not find a setting on the generated API key to allow for age restricted content to be viewed.

No, but happy to accept a PR for this.

Afaik there's no way of directly accessing restricted videos from the YouTube API without being logged in. In other words, you'll have to pass a YouTube account credentials by exporting your browser cookies and passing it to the client. This incidentally also allows accessing private/membership required videos/streams as long as the credentials allows it.

Quick search through code tells me you need to pass the cookie as a header here

muse/src/services/youtube-api.ts

Lines 67 to 73 in cc1f18b

	this.got = got.extend({
	prefixUrl: 'https://www.googleapis.com/youtube/v3/',
	searchParams: {
	key: this.youtubeKey,
	responseType: 'json',
	},
	});

and the generated header should look something like this

What about the ytdl library? I've used ytdlp (Python fork) in some personal projects and age-restricted video downloads work as intended.
Granted, I'm not sure how they do it, but it's probably not account credentials.

@Happyllama25 I've worked with yt-dlp before. Passing cookies to the client is the way. It's straight forward in code too, but since this project is written in typescript and doesn't rely on yt-dlp at all, we'll have to do on our own. But the proof of concept above should work.

Edit: you may have been on to something. It does work, sort-of by spoofing a TV client (?) Discussion on reddit here but apparently it's not foolproof if the owner of the video disables the option

It does work, sort-of

Yes, it works for me on my bot, something I did notice though is it seems to take longer to download an age-restricted video than a non-restricted one - not 100% sure, I have not done a 1:1 test of this.
