Login to YTMusic broken with cookiefile?

It seems that while the new musicapi_cookiefile option does result in higher quality audio for premium accounts, it messes up the YTMusic login, so when you try to list channel playlists, it doesn't work:

2022-10-07 17:13:20,220 INFO [955299:YouTubeBackend-5] mopidy_youtube: browse channel / library youtube:channel:root
2022-10-07 17:13:20,938 INFO [955299:YouTubeBackend-5] mopidy_youtube: youtube_music list_channelplaylists triggered ytmusic.get_library_playlists and ytmusic.get_library_albums: UCZtGOj7FTHPd2txgnbJS2kQ
2022-10-07 17:13:21,142 INFO [955299:YouTubeBackend-5] mopidy_youtube: youtube_music.list_channelplaylists exception Server returned HTTP 401: Unauthorized.
You must be signed in to perform this operation.

With the same cookie pasted into musicapi_cookie (instead of loaded through musicapi_cookiefile), it works (but no more high quality audio, as expected).

I think some extra " are the problem. A .replace() seems to help. I wonder if there is a proper way to do this?

This is currently working for me on one system but not another. Kubuntu 22.04, running from a console, playback works. Raspberry Pi OS (latest), mopidy running as a service with yt-dlp installed from pip (because it's not in the repo) I can't play anything back. It works if I revert to musicapi_cookie. Don't know if it's relevant but I can see a Destination: /var/cache/mopidy... in there. I have allow_cache = false in my mopidy.conf

My bad. My cookiefile wasn't writeable by the mopidy user. Fixed that and now it's working.

Are the high-quality streams available for all tracks? I've been testing using yt-dlp to list formats because now I've enabled the cookiefile in mopidy-youtube and signed up for youtube premium, nothing seems to have changed.

yt-dlp --cookies /path/to/cookie/file --list-formats 9zrYXvUXiQk and I don't see any high quality streams at all.

If I'm reading your debug output properly it does look like your fix is working and mopidy-youtube is selecting the high quality audio stream (format 141 is 256KBs AAC). Am I correct? if I am then it looks like the cookiefile format is broken, or yt-dlp isn't parsing it properly.

Yeah, the best audio format goes from 251 (medium) to 141 (high) when it is working, I think. So, maybe a yt-dlp issue, as you suggest? That's strange tho, given in mopidy-youtube, for the yt-dlp part, the Path of the cookie file is just passed without modification.

Actually, it isn't a Path, it's just a string. Probably should be a Path.

I discovered something.

If I just pass the video ID to yt-dlp, it doesn't find the high quality format. But if I convert that to a valid music URL, it does:

Without the Premium cookie?

In mopidy-youtube the whole url gets passed:

https://github.com/natumbri/mopidy-youtube/blob/develop/mopidy_youtube/youtube.py#L435-L441

One of the changes @ReneHollander made was to pass a music.youtube.com url, which is necessary for premium. Perhaps if you just pass the command line version a videoid, it uses an ordinary youtube.com url to retrieve?

This seems to line up with the yt-dlp docs, which say Music clients [which I assume are necessary for premium audio] can be specifically requested and is enabled by default if music.youtube.com.

OK yeah that makes sense. I am actually passing the Premium cookie, I set it in /etc/yt-dlp.conf because I kept forgetting to add it on the command line :)
