Playback error

[Medorex 0]

Hello everyone, I installed Emby premiere on a small and old DS216
initially I could see HD/FHD videos everywhere and only on my smartphone those in 4K, I tried to change some settings in transcoding and now I can play everything but only on the smartphone, on the TVs and on the PC (Wn) the message appears (translated from Italian):
-
Playback error
No compatible transmission is currently available. Please try again later or contact your System Administrator for clarifications
-
both for the TV connected via cable and on another in wi-fi
is there a way to restore the default settings of the transcoding section? Or can you help me to view everything on all my monitors?
I attach the logs, thanks
Medo

You server hardware can't handle transcoding of HVEC codex.

Meaning its not fast enough to do that.

Its transcoding because you use Firefox, that does not have native support of HVEC.

You transcoding speed should be over 1.

If I where you I would stick to h264 codex with AAC 2.0 audio.

That should work, if you use .srt subtitles.

@Medorexdoes this answer your question? For this old NAS you may want to focus your playback on content that can direct play without transcoding. 

You may also want to check out our Windows app because it can direct play quite a few formats without any transcoding:

Please let us know if this helps. Thanks !

Thanks for your advice, @Luke have already switched the server to my Win PC and everything works very well, thanks.
@Neminem thanks to you too but I would just like to point out the fact that with the DS216 for some time I was able to see files in 4K, but now the same ones that were ok before, now they are no longer, nothing has changed on the NAS, there have been no updates or anything else and regarding EMBY I have only updated the various versions proposed over time. For these reasons, as a newbe, I am inclined to think that the problem is not a hardware limit but of transcoding settings, I tried a lot but I was unable to come out victorious, this is why I asked the community, obviously I will accept your explanation, even if it does not fully convince me.

Thanks guys

They were probably direct playing before and now they are transcoding. When they direct play you should be fine. Maybe you were using a different Emby app, browser, or had different settings configured. It's just hard to say without seeing a specific example.
