[Ember-ruby]

iphone 8, ios 13

logs from finamp?
does it work in on other clients and if yes which?
jellyfin server logs?
are you transcoding?
see a pattern here...?

Finamp logs: https://paste.gg/p/anonymous/c238f1a4142447909d5abae177e9166e
Finamp audio logs: https://paste.gg/p/anonymous/4ab3e8c877bb41bdbcdb6dd737de7c0e
Jellyfin logs: https://paste.gg/p/anonymous/3c221e7311fe4066a5346fe36e81b27a

It works on Jellyfin web client and ios client, i don't have and android phone to try Finamp on

not transcoding, audio plays if i turn it on

What codec is your audio? OPUS and Vorbis aren't supported yet on iOS as iOS doesn't natively support those formats (it's dumb I know)

@UnicornsOnLSD thanks for your work on this app, I love it

I'm not super familiar with Flutter, but this might be a solution

That's a really interesting looking package, I'll do some testing with it :)

Not even transcoding it?? Also I’m kinda having this issue again, but now it only shows songs I’ve hearted on jellyfin web/iOS app, and yeah nothing opus is playing, annoying given that the vast majority of my music is opus

[jmshrv]

Transcoding should work since Jellyfin will then serve it as AAC, which is supported. As I said, this is an iOS issue so it isn't likely to get fixed in the future. I believe the libopus package that was sent here was for when you want to encode Opus audio in your app, so it won't be useful here.

Just noting here a comment I left on a duplicate issue - #236 (comment)

As said there, it would be interesting to see if it would be possible to use just_audio_mpv. In theory it should be possible, but there has been a lot of discussion in just_audio regarding whether or not bundling MPV in apps is legal. I'd assume that the MPV guys aren't too bothered based on mpv-android

The developer of just_audio gave a very good explanation on why MPV may not be possible in this comment - ryanheise/just_audio#178 (comment)

Apparently you can implement this by yourself I don't know it is complicated.

The post is a little bit old. It could be a solution but if I understand you need to implement your own player.

[jmshrv]

Yeah the libraries would only let me encode/decode those files directly, you can't plug them into Apple's player.

Maybe https://github.com/leinelissen/jellyfin-audio-player can be used for how to implement this? It's MIT and they have implemented opus playback

[jmshrv]

On iOS? It looks like they have the same issue - leinelissen/jellyfin-audio-player#97

I've looked further into MPV, it'll probably be possible as it's LGPL2 (some bits are GPL only but we can safely ignore them). The concerns around legality come from GPL3's Tivoization-prevention stuff.

In my case I can successfully play opus files (maybe it's transcoding?)
With finamp I couldn't even with transcoding enabled in the app

You're probably running into #269, which was fixed a while ago (but causes more issues in the form of #414 lol). It's not in a release yet thankfully.

Is that fixed in the AppStore version? I tried again but still couldn’t play music :(

[jmshrv]

It's not out yet, hopefully it will be soon. As I said, it breaks direct play at the moment so its probably a good thing that I was slow to publish it lol

[Chaphasilor]

@fuomag9 it should be out now. You can also try out the beta version which has support for transcoded downloads! :)
