Samsung Tizen app unable to play FLAC – infinite loading, no playback, forces AAC transcoding

[FrostByte 5538]

I don't see anything related to FLAC playback in the release notes but maybe try updating your Emby server (4.9.1.90) and Samsung client (2.2.8) to the latest versions.  And if you really want to go wild DSM 7.3 Update 1 is out.

Bonjour, je confirme depuis la MAJ de TIZEN OS les .FLAC lu par Emby tourne en boucle et la lecture ne demarre jamais je suis sur TrueNAS, Emby Server derniere version et TIZEN OS egalement

 

Hello, I can confirm that since the Tizen OS update, .FLAC files played via Emby get stuck in a loop and playback never starts; I am running TrueNAS with the latest versions of both Emby Server and Tizen OS.

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

Related specs:  A quick review seems to mention flac may be available for audio only playback, but not if there is a video playback with flac.

Correct, Samsung has never supported FLAC internal to video container.  Samsung only supports it as a music/audio file.  It may have semi worked before, but if it now doesn't because of a Tizen update and not an app update then it sounds like Samsung pulled the plug altogether. 

However, it should at least try to transcode.

attention se ne sont pas des videos ce sont des fichiers audio en FLAC qui sont lancé, tous mes titres en audio .FLAC ne passe plusdepuis la mise a jour TIZEN OS 9

 

Please note: these aren't videos; they are FLAC audio files that are playing. None of my FLAC audio tracks work anymore since the Tizen OS 9 update.

je precise que en DLNA mes fichiers audio .FLAC sont lu directement par la TV (je n'aime pas cette methode), avec jellyfin les .FLAC ne sont plus lu egalement 

 

I should point out that with DLNA, my .FLAC audio files are played directly by the TV (I don't like this method), whereas with Jellyfin, the .FLAC files don't play either.

Results in the dlna player will not always match what you see in the apps. We have seen cases where the dlna player supports things that the app player does not. By app player, I mean the one provided by Samsung for us to embed.
