SOLVED: FLAC not working in Web Player

[dolan-randall]

Hi there! I have some albums which are in FLAC format which won't play back in Firefox on the web player.

This is with Firefox 130.0.1, Windows 10, and Jellyfin Server/Web version of 10.9.10. I am using Intel QuickSync hardware acceleration for transcoding (when relevant).

FLAC albums play back fine on e.g. Gelli, but won't play back in the web player, where I get "Playback Error - Playback failed because the media is not supported by this client.".

That is odd, because at https://jellyfin.org/docs/general/client...c-support/ it says that the web player should support FLAC playback in Firefox. I would further have thought that even if it wasn't supported, that Jellyfin would transcode on the fly into something supported, not just bail.

Any suggestions?

This is a likely a metadata compatibility issue documented here: https://jellyfin.org/docs/general/server...containers

In the upcoming 10.10 we will have a compatibility option where you can force remux (copy flac audio to fmp4 container, no transcoding): https://github.com/jellyfin/jellyfin-web/pull/5986 to workaround such issue.

Thanks for the reply, that indeed sounds like the exact issue. Glad to see there's a fix/workaround already merged in! Sounds like that will do the trick. Looking forward to it!
