4k issues after several mins of play

Firstly good morning :-).

About 2 weeks ago my Vero 4K started struggling with 4K movies. I have up to that point watched many 4K movies without issue. I even tested some of the movies I had previously watched without issue and they now struggle to play.

So I start the film, the latest being Ghost in the Shell, everything seems ok unitl I reach the 6 minute mark. It starts to stutter, audio starts to drop and I have to stop. I also had this issue with The Greatest Showman. I have tried a complete reinstall, new HDMI cables, new LAN cables etc. The odd thing is my eGreat A5, dusty it may be since buying the Vero, plays all my 4K without issue using the same source (my win 10 PC using Hanewin).

So my set up is PC set up in office networked to the lounge using Netgear Powerline. I now Powerline is not ideal but as I said earlier, up until recently I had watched many 4K movies on my Vero, nothing on my set up has changed.

I must point out I have no experience with Linux, Command Lines etc. I have managed to upload my logs though;

I also managed to test my network speed which I think may be the issue although why does the eGreat manage ok on the same powerline?

I hope this makes some sense and I have uploaded the logs with some success.

Thanks in advance

Well 74Mbit is for sure not great. So it depends on which Bitrate your 4k Movies require. If you can post the mediainfo of 2 files that gives issues we can advice.

Please see the mediainfo section in How to submit a useful support request - General - OSMC.
You can also create the mediainfo-output of the affected media file on the OSMC device:

  1. login via SSH, user osmc, password osmc
  2. if not already installed: sudo apt-get update && sudo apt-get install mediainfo
  3. cdto the directory containing the video/audio material in question
  4. mediainfo -f "<media file>"|paste-log, where <media file> is your video/audio
  5. publish the returned URL here in this topic

Thx for your help.

Thanks for the speedy reply!!

I have Media Info installed on my PC. I tried to navigate using putty but I need to do a bit more reading on Linux :slightly_smiling_face:

I did a speed test on my eGreat A5, although it is internet speed and not network to PC speed and using the same cables it hits 198!??

Well Overall bit rate : 68.9 Mb/s + Overhead with an average network speed of 76.3 Mbits can lead to problems.

The Vero should normally have 92 Mbit with Iperf so I suggest that you check your powerline adpters. Maybe a resync brings them back to more throughput.

Alternative switch to fstab based NFS which might give you that extra bid of performance but it still sounds like a close call.

I assume it excludes the powerline connection to the PC, therefore not comparable.
You could run a Vero to Internet comparison (considering that your internet connection can do the 198 Mbit you gave above.

You might want to add “-R” to the client running on the Vero. This has the server send the data, which mimics what happens when you play back video from a NAS.

The eGreat still uses the powerline but direct to the Sky Q router. My setup is PC to Sky Router, to Powerline to powerline to eGreat & Vero.

I am not sure how I can test the Hanewin Server to eGreat speed, be interesting though. I will try and resync the powerline, they are Netgear 1Gbit and up until recently have managed ok.

As its only 07:11 am I am in awe at the speed of helpful response. Thanks guys
