some flac songs not playing in Firefox

[gabrielballot 0]

Hello,

 

Some flac songs are not playing in Firefox (they are well playing in iOS app). An error message appears :

 

Erreur de lecture

Aucun flux compatible n'est actuellement disponible. Veuillez réessayer plus tard ou contactez votre administrateur système pour plus de détails.

 

 

I am using the 4.2.0.40 version of the server but the problem already occured with the 4.1 version.

I am using Firefox 68.0.1 (64 bits) on MacOS

 

At principle I thought it was because the server was direct streaming 24bits flac songs but it seems the one is not 24bits... there is the output of ffprobe on this song that is making this issue :

This one doesn't work as well :

After a few investigation I believe it is because of the integrated image as stream 0:1...

Should I delete them or wait for an update compatible with it ?

[gabrielballot 0]

I did make the test :

ffmpeg -i Losing\ It\ \(Extended\)\ -\ Fisher.flac -map 0:0 -c copy Losing\ It\ \(Extended\)2.flac

and the new song plays well without the image

[Luke 42077]

So Firefox doesn't support that? I guess we'll have to add a transcoding condition for that.

[gabrielballot 0]

Yes Firefox desn't support that. When could I expect the changes in transcoding policy to take effects ?

It still doesn't work with the new release...

Sorry I did bu not have a chance to look at this. We'll try to get to it soon. Thanks.

This issue still exist in 2023. Any FLAC files with embedded image (album cover). Play without issues on Safari, Chrome, Opera...

Hi, yes it's a workaround we'll need to add for firefox to force it to have the server transcode the file in these situations.
