Certain videos switching language tracks without user interaction...

[attaboyBrad]

A particular Gerald Undone channel video (https://youtu.be/4OcP9XPb2kI) keeps changing languages mid-stream and I can't figure out how to change it back. It plays with the default English on Youtube web. Occasionally if I scrub it will restart playing in English for a second or two in Unwatched but then it changes itself back to Spanish without any interaction on my part.

I see on this thread that multiple audio tracks are a new feature, so maybe it's an issue with how the channel set their own audio tracks.

Here's a screen recording demonstrating the issue.

Having now watched the video... it was a pretty useless video. Maybe Unwatched was trying to spare me those minutes wasted.

Same thing is happening in this video from another channel, so it's not a one-off issue or channel specific.

The setting to switch audio tracks in the attached screenshot shows up in Safari and Chrome, but not in Unwatched.

When I click "view on Youtube" to open the video on Youtube within Unwatched, the video plays in the default language even though it doesn't show that setting in the player menu, but switches back to the alternate language when I go back to the in-app player in Unwatched.

EDIT: Here's another video doing it. Seems like it must be every video that has this feature available. Doesn't seem to be happening on iPad, so it must be something about the web player as it gets pulled into Unwatched on Mac. Weirdly, this video doesn't show the alternative language options when I open it under "View on Youtube" on Mac, but it did on iPad. In both cases, it plays in English when "Viewed on Youtube" within Unwatched whether it shows the alternative options or not.

Tried restarting and updating from Testflight. Was running 1.5.0 (174) on all platforms for all tests.

This seems likely to be relevant...

"YouTube announced on Tuesday that its auto-dubbing feature, which allows creators to generate translated audio tracks for their videos, is now rolling out to hundreds of thousands more channels."

Thanks so much for the detailed description and screen recordings :)

Definitely odd. Did I understand that correctly, the issue is exclusively happening on macOS and only inside the player?

I'm using the YouTube embedded player and for some reason YouTube doesn't appreciate having the embedded player blown up in size on macOS. Pip doesn't work, native fullscreen doesn't work, and neither does the quality selection (it was also stuck on 480p).

I tried a few things to work around this, but the best I was able to achieve was having a higher quality (but broken selection) combined with an "hide Unwatched controls"- fullscreen. So I fear there won't be a lot I can do about this, but I'll take a look at it.

Correct on "only MacOS and only inside the player". I tried and failed to reproduce the issue on iPadOS.

No idea if this is the same issue, but you might also look into whether or not speeds above 2.0 are working on your end on MacOS. No idea if you'll be able to fix it, but since it involves the Unwatched UI I suppose you'd want to pull those speed options for MacOS if you can't. Those speeds seem to work fine on iPad, so maybe it's also to do with whatever modifications you made to the embedded player for MacOS.

This issue is pretty wild, in one video it was switching from German to Spanish and in the next one it was Russian (I think) from the beginning. I first thought the youtube channel was highjacked!

I saw that the Vinegar Safari extension was recently updated to 'ignore the AI generated audio tracks when selecting the default audio track', so it would seem there is some way to do it--but they're replacing the player so that might be a completely different problem.

I saw the vinegar update as well, not entirely sure what they're doing.

I've played around with this for a bit and the only way I've found so far to avoid this without introducing other issues like the quality being limited to 360p is to run it as a native Mac version, which would be quite a bit of effort to do. I'll see if I can come up with something else.
