DirectPlay buffering on Sony Bravia A80j TV

[embyben 6]

I tried to play a 82GB movie for the first time tonight but it buffers every 20-30 seconds inconsistently.

The stream is DirectPlay. 

Emby Server 
Version 4.7.14.0
HP Gen8 Microserver  - Docker Container - networked using MACVLAN (current setup)
Intel(R) Xeon(R) CPU E3-1265L V2 @ 2.50GHz  - 16GB RAM

Player
Sony Bravia A80J 65" Android TV / Emby App

Network
8 Port Unmanaged Gigabit Switch

I can't see anything obvious in the logs. Can anyone else help?

I'm suspecting a networking issue perhaps. 

How can I stop the buffering please?

Hi, have you tried lowering the in-app quality setting to transcode to a lower bitrate? It's possible the bitrate is just too high for the connection.

Hi @Luke, thank you for your reply. 

I haven't tried transcribing, but yes that would probably work.

I'd like to find the bottle neck and get my network running at optimal. 

I'm going to "dumb down" my over engineered network to remove all the sub-interfaces, routing and put my server on the same subnet today and try that. (big project).. 

Failing that, is there any reason why the A80J TV could not handle 66mpbs? (I even added a gigabit USB NIC to tv)

So this isn't a remote connection?

Not a remote connection. Same house.

Hi.  The TV may only be designed for 100Mb/s network over its network interface.  Many TV manufacturers skimp on this hardware because most people don't use it anymore.  Have you tried using wireless?

It also could just be that the TV's processor has trouble with content that has a bitrate that high.

I just took apart my network.

It wasn't the sub interfaces. It still buffered when being routed. 

I put emby server on the same Subnet as the TV and there was NO BUFFERING!! very happy.

However, now my server is not in a DMZ and I want to find why routing caused the lag?? The firewall is a Intel(R) Core(TM) i3-5005U CPU @ 2.00GHz
4 CPUs with 4MB RAM which should be fine. 

I'll keep troubleshooting. 

Thanks for your help.

Glad you chased it down.  Thanks for reporting back.

Turns out my pfSense had a "Traffic Shaper" on as the culprit. 

 

All sorted now.
