No, do not change this at all. By using YES+, you allow Google to track usage of users and so to establish profiles based on what they search, they browse and they watch, using the YouTube requests made by the extractor. The NewPipe projects aim to protect as much as possible users' privacy, so we will not accept this change globally.

Instead, allow only the ability to set the YES+ cookie in YoutubeMixPlaylistExtractor, but disable it by default. That's I wanted to do in a future PR (because I wanted #863 to be merged first, but I have some changes to do in it first). Based on the changes of this PR in YoutubeMixPlaylistExtractor, you can find what I did here: https://github.com/AudricV/NewPipeExtractor/commits/consent-cookie-yes%2B-for-yt-mixes-option.

If you want to apply them, you can reuse (partially or not) my changes, but do not add the Content-Length header in the requests like I did (see #863 (comment) to know why I say this).

Then enable usage of this cookie value in test classes of YoutubeMixPlaylistExtractorTest, for each test (like I did).

Happy to apply these changes, although if we only use the YES+ cookie in tests, would that mean the mix extractor won't work for users in the EU?

Btw, any clue how I can test this extractor in NewPipe app? 😅
I've tried searching for playlists, but none of them seem to be youtube mixes.

Do you really need the usage of this? If not, can you remove it, please (not really an issue)?

The failure was not on the stream count, according to the latest scheduled tests (that you can see in the Actions tab of the repository), it was on the first item returned by the search results. The latest run does not have this issue, so I think that's a intermittent issue which can be ignored.

You may revert these changes if you can't reproduce them.

It seems like the metadata for this particular video changes back and forth.. When changed the name, the image started to fail, and then there were only 3 streams reported. Perhaps we could just use a different video here?

As the goal of this test is to test if MetaInfos are extracted properly from videos metadata, you will have to find a new video with a MetaInfo and update all the relevant assertions instead of removing the test (and maybe also the test class name and the name of the folder in which mocks are saved).

No other tests in this file seem to be overriding expectedMetaInfo. I actually suspect the YoutubeStreamExtractor currently can't extract meta info -- it is contained within the videoPrimaryInfoRenderer and videoSecondaryInfoRenderer objects rather than there the current YoutubeParsingHelper.getMetaInfo() is looking for it. How would we better address this?
