Lag with XBOX one

Hello,

I am trying to using Plex on XBOX one via a Synology NAS
Synology is a DS216+II (Intel Celeron 1.6 Ghz, 2 processors, 1Mo RAM, supposed to be able to transcode 4K film …)
My film is in 1080P, everything wired via Ethernet cable, work in local network
Version:
Plex server on Synology is 1.3.4.3285
Plex player on Xbox is 1.8

Issue : with Plex the film is stopping on a regular basis (when buffering?)
it seems that the Plex server is transcoding as CPU of my Synology is 99% full
I don’t understand why it transcodes as with Xbox media player I have no lag at all (but no subtitle) and a direct play.

How could I fix that issue?

Thanks in advance

Without us knowing what you’re playing that is causing a transcode there isn’t much we can try and diagnose.

In your Plex Media Server.log the Xbox One app should be saying why it has requested a transcode. This support article explains how to get that log so we can try and advise you more.

Try to turn off subtitles, that changed my cpu usage from 96-99% to around 30% on my nas

Yep, because Plex don’t support subtitles :((

Still waiting on the Plex UWP on XO, but I’m hopeless on this topic.

Maybe I’ll switch to KODI if the release a UWP app…even if I bought the plex pass.

Plex on xbox one is useless If you need subtitles. If you have hard-coded subs it works…srt works fine from iPad.appltv and such. I even tried to use my qnap. To transcode with subs and play to TV via hdmi. Worked fine. Then again xbox one is perhaps the slowest player you can use.

@Chickencasual yep, Plex on XO is really slow and useless if you need subtitles… but I heard that the UWP version of Plex is supporting subtitles and is much faster.

Still don’t know why it’s taking so much time to migrate a win10 app on XO.
