Buffering issues with 4k File

Help and Support Vero 4K / Vero 4K +
1

hi guys i tried the update but when i try to add the line that you recommend </etc/apt/sources.list>
i receive permission denied. I can’t play the jellyfish video with 140 bitrate. i have many buffering issues. I have it wired with the nas and the router. I use nfs fstab like you recommend and the uhd large files i have buffering. How i test the speed with iperf? And how i change the buffer on advancexml?

Hi @vagos1103gr,

I moved your post to a new thread as I don’t think your buffering problem directly related to what was discussed in that thread.

Did you use sudo nano /etc/apt/sources.list ?

How do you want to play a 140 Mbit file over a 100 Mbit LAN connection? Buffering only helps to buffer for peaks. Any file above 86Mbit average bandwidth will not be able to be played via Ethernet unless you get a USB Gigabit dongle.

Install iperf with sudo apt-get install iperf3 you then need to install it also on your NAS. You then would start it on the NAS with iperf3 -s and on the Vero4k with iperf3 -R -c <IP of the NAS>

No need to change that anymore, latest OSMC update ensures best settings on Vero4k

thanks for the fast reply. I had before an green usb gig adapter and i return it cause i was still have buffering. I order now one from amazon that has the chip rtl8153. i install the iperf3 on qnap nas and also to the vero , i run iperf3 -s to the terminal of my iMac connecting with the vero says Server listening on 5201> and after iperf3 -R -c 192.168… but nothing is happening. Any help?

4

So 192.168… is the IP of your iMAC?
Any firewall blocking that port?

5

no the ip of vero

6

i tried also iperf3 -s ip of the nas and after Server listening on 5201 iperf3 -R -c ip of the vero but nothing

7

also after this update from the previous thread i watch an uhd 55 bitrate and after skipping forward the movie was going shaking

8

Well reading help

9

yes sorry i did that, i receive :osmc@osmc:~$ iperf3 -s

Server listening on 5201

iperf3 -R -c ip nas
nothing

10

Wait Wait.
So you are running the iperf3 server on the the Vero not on the NAS?
If that is the case than you run the client on your NAS or the iMAC with iperf -c <IP of Vero>

11

i did that :osmc@osmc:~$ iperf3 -s

Server listening on 5201

iperf -c ip of vero

i run the terminate from my iMac connecting with the vero. i download the iperf3 on my qnap i have a button to open but doesn’t do anything. I don’t know if its running. After i run the osmc@osmc:~$ iperf3 -s

Server listening on 5201

iperf -c ip of vero

on the terminate connective with vero but nothing

12

Sorry this all get’s a bit confusing.

  1. Run on the vero iperf3 -s
  2. Than run on your mac local terminal ping <IP of Vero> and show the output here
  3. Than run on your mac local terminal iperf3 -c <IP of Vero>
13

i did that and i receive :osmc@osmc:~$ iperf3 -s

Server listening on 5201

ping ip of vero
iperf3 -c ip of vero
nothing

14

ping ip of vero nothing?
What is the IP of your Vero? What is the IP of your MAC?

15

Ping ip of vero 192.168.0.13
ip mac 192.168.0.25

16

So if you execute ping 192.168.0.13 on your MAC you don’t get a reply?

17

what i do after?

19

the response continues…

Ctrl-C to interupt.

And now with iperf3 -s running on the Vero you run on the Mac (where you just did the ping) iperf -c 192.168.0.13
