Emby won't stream one FLAC file which is not corrupted.

[xphorm 1]

VLC Player plays it ok, but Emby just tells "Playback Error: No compatible streams are currently available. Please try again later or contact your system administrator for details."

Nothing useful in log file. PM me if you want to get that FLAC file.

Hi there, let's look at an example. Please attach the information requested in how to report a media playback issue. Thanks!

I don't really have that much time for playing with Emby, but if anyone wants FLAC file to examine, I will give it.

Sure you can PM it to me, but still need information on what client along with the server and possible ffmpeg log for this file.  As playback for me and you can be totally different.

4.7.9.0  Linux 64bit

Client is Chrome web browser 107.0.5304.121, also Linux 64bit

Still looking at the file but appears to be embedded metadata related as stripping tags file plays fine drag and drop into Chrome where original will not play.

[Happy2Play 9783]

Further testing appears specific to the embedded image and not tags, as soon as I removed the image it played.

But reapplying the same extracted image still worked so to me there is something wonky with the way it was created.  

 

Note my drag and drop test method actually eliminates Emby and shows it is a file or browser issue.  But should be as easy as removing covers and readding covers.

Follow up even though programs see the image ffprobe throws an error on mimetype but does not when image is extracted and readded.

Thanks for finding out what caused it! Still, Emby could be a bit more robust and if it can't read picture data, that shouldn't be the cause the audio can't be played, don't you think?

True but @Lukewould have to comment on that, but in the end the browser itself chokes on the file.  Not sure if failing over to transcode would make a difference.

Not seeing any errors in server log but get "Playback Error: No compatible streams are currently available" with original file trying to play in Emby.

Fixing the embedded image plays in Emby.

Only tested in browser.

BTW, file plays in Safari, so finally everything boils down to robustness. I think saying that this is not Emby's problem hurts this fantastic project. At least, Emby could warn user some content can't be played before attempt to play it.

True but player capabilities are browser specific.  But can say Edge and Chrome have issues with the file but Firefox will play it.  Emby does not control how robust the browser play is just report back when the player itself chokes on the file.

Ah ok, somehow I concluded the problem is strictly not just in browser. Anyways, somwthing can be done to increase robustness and if malformed file is detected than it may be transcoded to something else.

Hi, we do already have this for video but it hasn't been extended to audio yet. Thanks.
