Looks like a lot of people are having this issue

Came here to report the same! MacOS

In the playlist durations are correct but doubled when playing and remainder is just silent.

@karniv00l Since you're already familiar with Spotube codebase and happens to have a Mac, can you try using different available YouTube codecs in MacOS and see if this happens in other codecs as well?

You can see the available codecs by adding print(trackManifest.audioOnly.map((info) => info.codec.mimeType)); before following Line-435 https://github.com/KRTirtho/spotube/blob/aba1ba932592923720a36395c057f78820dafecf/lib/provider/Playback.dart#L435-L444

I'm actually not familiar with the codebase at all 😅

Changing codec from audio/mp4 to audio/webm results in error.

I've also inspected some variables in this class, and it seems like YT and Spotify tracks both reports correct length and correct song (with some exceptions). So I would say it may be some bug in elsewhere, like in the core of the player?

Yeah audio/webm in Apple devices is not supported 'cause it's Apple

So it could be flutter audioplayers plugin?

@KRTirtho @karniv00l .

Thanks for looking into this. It's really an annoying bug in the core :-)

Hi, As a macos user, I also experience this bug. after some investigation, this seems to be a rather low level bug. Downloading the audio/mp4 file played by spotube, then trying to open it with QuickTime, the display duration is also wrong. With VLC, the correct duration is visible.

After renaming the file, as suggested by https://apple.stackexchange.com/a/443882 , the correct duration is visible

This isn't solved @RaptaG

So I replaced audioplayers for macos with just_audio and it seems like this double duration issue is fixed. You can download the latest nightly to check if it's working for you

@KRTirtho I confirm the nightly build has correct song duration on macos Monterey
