Vero4k Video playback aborting since update to 2017.12-1

Hey Folks,

I just upgraded my Vero4k to the December update this morning. Since then I seem to be facing issues playing back video files.
Some videos (not all apparently) will start playing for about 1s before stopping and returning me to the selection screen. I had no such issues before the update.

Differences between working and non-working case appear to be these entries in the Kodi log:
ERROR: Read - Error( -1, 103, Software caused connection abort )

Could anyone do me a favor and take a brief look at the issue on hand?
Greatly appreciate your help!

Can you try playing the file back locally?


I have the same issue after December update. It’s also on Vero 4K.

Did you try playing back locally?

Hi Sam,
I tried playing the same episode from USB, and it works just fine!
I then rebooted my Synology NAS to make sure, but am still seeing the issue when streaming via SMB…

Hi, I just received my vero 4k today, I did the update. Trouble playing 4k streams, pausing. Saw the sad face a few times, and then the box restarted. Plugged it out, to try sort it. Using a LG c7 tv. Had a chromebox before this with libre elec. I was expecting trouble free 4k hdr. Should my resulotion be set to 1080p. 24 or 23.973 something else for 4k? Thank you.


I’m having this exact same issue. Since the December update video files streamed via SMB from a NAS drive are failing to play on my Vero 4K. Occasionally I can get a file to play by attempting to run it several times but as soon as I try to skip forward it will abort playback.

Hopefully I’ve uploaded this log correctly:

Please tell me there’s a way to roll back to the previous build as my entire media setup has been rendered useless by this update. :frowning:

Enable Adjust Refresh Rate and you’ll get HDR. Start a new post if this isn’t the case and we can advise.

Thank you. Played another 4k stream a while ago and it was OK. Maybe it was the time of day (5pm) which was the problem. Even though I’m supposed to have 40mb. Thank you for the speedy reply. Very happy with the box. And I love that when you plug it in it turns on, not like my chrome box with libre elec. I had to press the power button on the box itself. Hince not been able to hide it away behind the tv on the wall.

Your log shows you press the Stop button and this causes playback to end.

22:18:28.388 T:4074873424   DEBUG: OnKey: guide (0xe0) pressed, action is Stop

22:18:28.388 T:4074873424  NOTICE: VideoPlayer: waiting for threads to exit

Can you enable debug logging and clarify what kind of share smb:// is?
Assume local playback is OK


I had appended a log with debug logging to my first post:

If you need debugs logs of local playback (which appears OK) or anything else, let me know and I will obtain those as well.

The SMB share at is a Synology NAS using all default settings (no tweaks to smb.conf), mounted from Kodi rather than at system level, and all working fine up to the time of update. Vero4k is connected via cable.
What other information about the share and setup would you need?


PS: Is it expected that ffmpeg debug log is dropping character(s), s.a. “Tho’s” instead of “Thor’s”?

I think some network test between Vero and NAS would not harm.
Suggest to use iperf/iperf3 to check throughput and maybe smbclient to get a file for testing.
Let me know if you need more explanations

Hi fzinken,
Not sure what exactly you are looking for from smbclient, but let me show that I can connect and get a file without issues…

this is what I was looking for and a good proof that outside of Kodi there is no network issue.
So means we have to look inside Kodi. Actually I wonder, you should be able to use the Filemanager within Kodi to check how long a transfer from the Server to the emmc would take or? I think the SMB sources should be visible in Filemanager, could you check?
When we know how long it take to copy the same file within Kodi than we know if it is a Kodi SMB problem or actually a videoplayer issue

Ok, I see. Well I successfully copied the same file from NAS to Vero within Kodi Filemanager and get something between 4.9-5.2MB/s, for a total of 82sec.
Anyhow, this is a tiny file, DVD rip really. Should not take up a whole lot of bandwidth at all (see overall bitrate @MediaInfo in first post).
Any thoughts where we can go from here?


Edit: Just found evidence that I probably copied the file from the NAS directly back to another share on the same NAS that I had mounted a while back. This could at least impact the achieved speeds, I guess. Will double check later.
Edit 2: Indeed, copied from NAS back to NAS by mistake. NAS to Vero is yielding much better speeds around 10.4MB/s.

Well that is definitely much lower than what smbclient gave you and at least one of the files you had in your mediainfo is above that .

Complete name : The Boondock Saints (1999).mkv
Format : Matroska
Format version : Version 2
File size : 6.47 GiB
Duration : 1 h 48 min
Overall bit rate : 8 539 kb/s

Well maybe @sam_nazarko has an idea what might have changed in Kodi but other than that I only can suggest to try fstab mount smb shares which will give you the same throughput as smbclient

You guys are all playing back through Ethernet or WiFi?
After having quite some issues with WiFi, I decided to put an ethernet cable all of my issues went away.
The issue I had was that some devices on the same WiFi were causing the link speed to be lowered sometimes to 1Mbps and that cuased the data-stream to cause stutter even on Video’s.

It’s not actually. You are confusing megabytes MB and megabits Mb. :slight_smile:
8539kb/s = 8.5Mb/s = 1.06MB/s which is still much less than ~5MB/s I got using the Kodi Filemanager…

Use wired only

You are right, didn’t consider the lower case “b” in Mediainfo.
So than I am out of ideas why it fails playing back via SMB but is fine when playing locally
