VERO4K+ unable to play x.h265 HDR 4K and crashes [SADFACE] 2 to 3 min in to the Movie [Isolated to KODI 18]

Reposting this to OSMC community to get feedback on similar user experience…

Issue:
VERO4K+ unable to play x.h265 HDR 4K and crashes [SADFACE] 2 to 3 min in to the Movie. Replicated with 10+ 4K HDR movies files and with 3840x2076 resolution and 3840x1600 resolution

SETUP:

  • VERO4k+ running on KODI latest connected to Samsung Samsung UN60KS8000
  • LAN Connection with 1Gbps
  • NAS hosted KODI DB
  • Mount type: NFS [Based on ip]

Investigations done to date:

  • I installed htop program and monitor the 4K+ resources while playing 4K movies
  • As per htop reason for the sad face, hanging after 4 to 5 min in to the 4K movie is that due a memory is maxing out and possibly a memory leak
  • Whe movie started playing memory is around 700mb and with time it will keep increase to max 1.8G and then all 4x CPUs will max out resulting in freezing first and after couple of min it will crash and show SAD FACE. [Refer to the video I made]
  • I have replicated the same with cache enabled and also when cache disabled
  • Speed test results attached between the 4K+ and NAS showing no bottleneck with LAN speeds
  • Tried to copy the file to a USB3 and play locally but when select the file to play Sadface directly and reproducible

I promise you with KODI 17 this issue was not present and I was playing the same 4K movies without any glitches…

This is easily reproducible as HTOP will give a clear picture of what’s happening. Hopefully this issue also fixed part of this update.

I am happy to provide any logs or other info you and your core team require to fix this issue.

NOTE:
Same file playing over my Synology NAS hosted PLEX server and my Samsung TV PLEX APP without any transcoding [This feature called “Direct Play” in PLEX world] and whole movies are playing without any issues. Note that Samsung TV got 100MBPS LAN.

I am currently using PLEX to watch the 4K as my OSMC4K+ BOX unable to play these files. Given my PLEX app playing the file, I know my file and network is not an issue.

#4

Please post full logs – not just Kodi logs; particularly as there’s an audio issue in your log.

#5

@sam_nazarko Please provide steps for this. I am running the KODI Debug logs via the advancedsettings.xml

<loglevel hide="true">2</loglevel>
#6

Just select all logs via My OSMC when uploading

Sam

#7

I am uploading these manually by copying the KODI log via Cyberduck and then uploading via my MAC. Please inform where to copy the extra logs and I will upload them.

I am unaware of Upload all option and need more info, if this is the preferred approach. Also I want to know when I do this post crash will this upload all logs you need…

#8

To get a better understanding of the problem you are experiencing we need more information from you. The best way to get this information is for you to upload logs that demonstrate your problem. You can learn more about how to submit a useful support request here.

Depending on the used skin you have to set the settings-level to standard or higher, in summary:

  • enable debug logging at settings->system->logging
  • reboot the OSMC device
  • reproduce the issue
  • upload the log set either using the Log Uploader method within the My OSMC menu in the GUI or the ssh method invoking command grab-logs -A
  • publish the provided URL from the log set upload, here

Thanks for your understanding. We hope that we can help you get up and running again shortly.

I have exactly the same problems. I posted recently in context of a chapter skip sad face crash, but I also find I can only play my 4k files for a short period before the sad face event.

#10

@mtv / @sam_nazarko Attached are the log URLs for 2 separate reproduce with two different files. Thanks for helping me with this issue…

Just another note, I have completely refresh the Vero4K+ via rebuild last SAT to isolate any other filesystem and addon issues…

Good news is that Sam already fixed the FF / RW issue with the next update… however I understand your pain with other issue as this is why I have spend days and days to present a clear case to OSMC team…

I know we will get a fix soon just need to rally others… Really appreciate your feedback on this topic.

To test this update: (From SAM)

  1. Login via the command line
  2. Edit the file /etc/apt/sources.list
  3. Add the following line: deb http://apt.osmc.tv stretch-devel main
  4. Run the following commands to update: sudo apt-get update && sudo apt-get dist-upgrade && reboot
  5. Your system should have have received the update.

Please see if the issue is resolved.

I also recommend you edit /etc/apt/sources.list again and remove the line that you added after updating. This will return you to the normal update channel.

I posted logs on this a month ago but no one replied. I’m not in a position to do any testing at present, but good to know I’m not the only one who is finding there are still some major issues post migration to K18.

#13

Do you have a link to this? I thought you had issues with seeking in files. That has since been fixed.

#14

Does enabling passthrough as a test (you might not get sound) fix the issue?

#15

Yep, seeking was the first thing I noticed to cause the sad face crash, in this thread I also posted a log of a regular in-play crash with a 4k file. It’s been completely reproducible.

#16

Even with staging?

#17

Have not had chance to check that as I’m away, but will look out for that when I return.

#18

Cool. I think skipping is fixed now. I’d be curious if you still experience issues with crashes a couple of minutes in.

#19

@sam_nazarko I also tested with “Passthrough” and issue is still reproducible. I will upload a log with “Passthrough” enabled soon.

#20

@sam_nazarko I believe you are right on the sweet spot. I have done a mistake from myend… When I set the allow passthrough I did it via the VIDEO OSD and it didn’t set automatically for other movies.

I have now changed it via the main settings screen–>System -->Audio and as you predicted issue is not happening however I am not getting sound in my TV as Audio tracks in these movies are TRUE-HD and my TV not supporting these Audio formats.

Hopefully this will allow to narrow down the issue… Logs with “Passthrough” mode enabled for two movies above attached with 10+ playback on each.

Hopefully fix will be available for these soon…

Batman.v.Superman.Dawn.of.Justice: / Star.Trek.Beyond: / Alien.Covenant: with “Passthrough” mode enabled:

Can’t Upload and getting below error:

osmc@MBRVero4Kplus : ~ $ grab-logs -A
Logs successfully uploaded.
Logs available at https://paste.osmc.tv/{“message”:"Documentexceedsmaximumlength.
osmc@MBRVero4Kplus : ~ $

Other Noticeable observation was CPU and RAM usage was significantly less with “Passthrough” mode enabled:

#21

Reboot twice and try again - logs most likely are too big.

#22

Any update on the fix? Will it be available part of current update or should I wait for next month update?
