Unable to play 4k - Direct Play

#1

Hi,

I have plex server installed in a Proliant N54L server that runs correctly with the last version.
My TV is a UE55JU7000 model which runs 4k content correctly when using a hard disk or pendrive connected to it.
I have the last version of plex client for this TV.
I have tried playing 4k content using direct play (not transcoding, just playing in the original quality) and its not possible to run it, it is buffering or stopping all the time.

My local network connection is gigabit and CAT6 cable (i dont use wifi connection). I have tried connecting a computer to the RJ45 cable that i use to connect the TV ( to test the speed) and its transferring files from the server at 90-100MB/s speed, so all seems to be OK in the network speed.

Any way to solve that problem?
I have a Xbox One X (the last xbox version that runs 4k games) with plex client installed too, and I have the same problem with 4k content.

Thank you.

CAT6 is a Gigabyte ethernet (1000 MB) cable, but network ports on Smart TV’s are fast ethernet (100 MB) so huge files like 4K mkv’s will struggle to direct play, direct stream or even transcode.

Unless your Plex Client (The Orca one basicly, other ones like the official are crap…) is really good at playing stuff and you have a Gigabyte port available on your device forget playing any file with bitrates higher tan 30-35 Mbps.

Thank you for the answer!

2 questions:

1.-
So which would be the solution or the best way to play 4K on a Smart TV?

2.-
On the other hand, the problem is that this exact problem is happening in my Xbox One X when using the Plex client too (the last console of Microsoft), and it has Gigabit Ethernert port. So i am not sure why on the Xbox One X its not playing correctly and its buffering everytime with large 4k files.

Thank you.

Creo por tu nick que casi que en español mejor :wink:

La respuesta simple es… No lo sé. Me han dicho que la nvidia shield funciona bien y tiene puerto gigabit, pero es que básicamente NINGÚN hardware soporta tantos drivers como una smart TV Samsung y no hay ninguna aplicación que haya probado que funcione tan bien como la de Orca.

He probado la oficial de Plex para Samsung Tizen, la de PS3 y 4, la de iOS, por web y Apple TV y es que no hay color. A no ser que haya cambiado mucho el tema desde la última -y por lo que os leo a quienes probáis plex desde otros dispositivos con software desarrollado por ellos- los que tenemos una samsung J series o anterior (con puerto fast ethernet) estamos poco más que jodidos.

I can’t promise this will do the trick, but remember that 4K video always needs the app to be set in Direct Play mode manually.
When you leave it in “Auto” it will always start transcoding because 4K files are way beyond the 20K limit which will force a transcode if the “Auto” setting is used.
Also 4K files need to be in a Samsung compatible format. Depending on the codec used there are also limits to the bandwidth, check your manual there should be a table like the one in this post.

@petazetas I have a Samsung UE55KS7000 and solved by 4K buffering issues by switching to wireless. I was fully 1Gbps but the 10/100 NIC in the Samsung TV was a bottleneck. If it helps, my router is only about 60cm from the TV. My Plex server (with 1Gbps NIC) is upstairs but cabled into the router with cat6.

I’ve successfully DirectPlay’ed files upto 75Mbps this way. Previously it buffered at anything over 50Mbps. I don’t know about DirectStream - my server isn’t all that powerful.

I don’t agree at all.

I run a 100Mbps LAN network and my TV will play directly from Plex over DLNA without any problem (so not a network issue).

When using the Plex client I have buffering problems.

Therefore it must be within the Plex client that the problem lies.

Quite literally if your bitrate is under 100 Mbps there is no reason a 100Mbps link shouldn’t be able to manage it unless it’s overburdened otherwise.
