Vero 4k stuttering suddenly

#1

i have my vero 4k for a couple of years and now suddenly 4k movies are stuttering and nothing chaanged ? is there something new with the last updates ? 1080P movies play fine , when i start a 4k movie like Dunkirk it starts and sometimes it starts stuttering , i see it with many other movies now.

Check your network throughput with iperf3 (both directions) and also try to play the file from a USB stick to exclude the network as a source of the issue

i already tried playing from a USB harddisk , same problem so it is not the network and the network did not change , a week ago it was fine

#4

Next step is to provide debug enabled logs.

Thanks fzinken , i will do that tonight i am at work now

Adjust display refresh rate: Off

Change this option to On Start/Stop

If that does not help I see that you are using Kodi SMB mounts. Switching to a kernel mount (fstab or autofs) may improve your network performance.

i will try that thanks, just instaled a NUC with kodi and there are no problems with 4K files playing fine, i do not know where to find autofs can you tell me ?

Our Wiki has lots of useful information. This would be a good starting point for you:

Improving the mounting of network shares will not help if the playback problem is also happening with USB storage guys. :slight_smile:

i totally agree and also the same files i play with fresh installed NUC with kodi and there are no problems with 4K files are playing fine, strange is that a week ago everything was fine and now it is stuttering and buffering (only with 4K files) maybe something to do with updates OSMC ??

#12

Did you change adjust refresh rate yet?

#13

yes i did same problem and what i also did was a complete fresh install on the Vero also did not help,maybe someone will buy it :grin: because the NUC is really fast and no problems with 4K

The problem is with throughput to the NAS:

2019-07-10 16:22:40.978 T:3531158240 DEBUG: CAMLCodec::GetPicture: VC_BUFFER LEV:0.00 ttd:-70645921ms x:100.000

The log doesn’t show any attempt to playback from USB.

Sam, i play the same files to my NUC no problem, why should i lie about playing the same movie from USB disk and that is fine ? so you say my NAS is to slow ? how can you explain that the same file from the NAS to the NUC has no problem ?

#16

A log with Adjust Refresh Rate enabled would be useful; as keeping this setting off is not optimal.
You have an original Vero 4K which is limited to 100Mbps. Your NUC probably has a 1000Mbps Ethernet port.

There is a significant amount of overhead by adding shares via Kodi. An OS level mount would probably overcome this; but 4K UHD rips may benefit from a Gigabit Ethernet port.

#17

correct my NUC has 1000Mbps, also my switch so that is no problem , if understand you correct the Vero 4K+ with 1000Mbps would be better ? or i have to dig in and try autofs ? correct me if i’m wrong.

With the Vero 4K + you shouldn’t need to use autofs; although it would still be advisable.

ok i will try to get the autofs working on my Vero 4K, new for me but let you know the result

#26

i made changes , i hope i did it correct , what i did was made the autofs with Putty, set auto refresh rate to on start/stop (fzinken told me) here new link with logs , was watching John Wick 2 , stuttering and many black screens for a second
