My guess would be something is triggering transcoding there which is simply too taxing for your NAS, could you provide ffmpeg logs for those unsuccessful playbacks?

Hi, many thx for your quick answer, this evening I will make the test again and download the ffmpeg logs.

PS in case if confirmed that the problem is caused of transcoding activation, is there any way to force emby to go on direct playback as I suppose happen if I play the movie towards Smart TV?

 

thx

Emby will direct play if capable.  Without knowing why it is transcoding we can only guess.  Best guess would be unsupported audio forcing full media conversion as HEVC does not play well with our HLS delivery protocol.

Without looking at the logs and determining the reason for transcoding, hard to guess. But you can't 'force' DirectPlay, you can only provide media in a format that will not require transcode. 

Edit: Cross-posted, I guess.

No need to turn Debug logging on, just play something and if transcoding occurs, ffmpeg-transcode log will be created for that session.

Hi in attach 2 exmple of two movies didn't work.

let me know if readable or if I have to copy and past directly here the content 🙂

I hope you can help me , this two movie are playable normal using the smart tv player, but due a samsung limitation only the default languagge is showed so I cannot swap le audio.

I have other 4K movies payable from emby without problem but logically I cannot attach the log (if I undestood well only when emby trascodind the logs are created 🙂 )

thx

Correct the client does not support these graphical subtitles (pgssub, dvdsub) and is force to burn them in, causing a full transcode of the media.  Getting srt subs would/should resolve the issue.

thx , is there any possibilities du to the fact i don't use subtitle to set someting in emby to skip it and not transcode ? 😞

the most of file I had has this problem so I suppose this type of format is quite common, so we cannot choose to skip the transcode ?

The NAS is not be able to make this job and blocked😞

thx

If you don't use subtitles you can disable them via user icon-Subtitles screen, set mode to no subtitles.  But not positive if this is a global or per client option though.
