Occasionally playback (audio and video) stops for a second or two, before rendering a garbled frame and continuing. If a movie does this, it will keep doing it every 10-15 minutes, sometimes even more frequently.
It’s happened with several different videos and I’m unsure how to troubleshoot it. They’re all decent rips, hardware accelerated and I get nothing in the logs. I have installed all updates and run only two plugins - a filesystem watchdog and a subtitle downloader.
Attaching a sample screen from Spider Man Homecoming (H264, AAC 5.1).
Whats my next step - how do I troubleshoot this?
Can you try playing back something that worked without issue before?
Can you post debug logs?
Thanks for the quick reply. Some more info:
It’s been happening for at least 2 weeks. Everything is on local storage, USB3 drive. Both the Vero and these files are all new so I don’t have any “known good” samples or previous state to compare too.
Can you help me with the debug log? Im not sure how to activate nor find and share them. In the menus there’s a bunch of different settings for logging. “Events” doesn’t provide anything (other than the occasional library scan failure on poorly named files) and the other pukes debug output over the screen (not sure if it logs anything tbh).
Thanks for that link! (Note to whomever is in charge of that page - some information needs updatingSettings -> System -> Logging -> and selecting Enable Debugging should be: Config (gear icon) -> System settings -> Logging (at least in the default skin). Similar, but different enough to be confusing.
Here’s my log: https://paste.osmc.tv/erubozuxod
I took these steps to create it:
enabled debug logging, rebooted
resumed “Spider-Man.Homecoming.2017.1080p.BluRay.H264.AAC-RARBG.mp4” at point just before corruption
video froze, audio desynced, subtitles continued on. (when resuming near corrupted segment, it sometimes crashes, it sometimes desyncs like this.)
stopped playback once it had stabilized and was running well again.
ran paste-log /home/osmc/.kodi/temp/kodi.log
Here’s MediaInfo output for three files I know has caused issues lately.

Settings -> System -> Logging -> and selecting Enable Debugging should be: Config (gear icon) -> System settings -> Logging (at least in the default skin). Similar, but different enough to be confusing.
The default skin is OSMC for which the instructions are correct so you either changed your skin or you use the testing branch of Kodi (Leia) for which OSMC skin is not available.
Gear icon could just as easily signify settings as it could config. I don’t see this as a significant issue at all.
Sorry, I thought the trouble shooting article was related to the Vero 4K, which I am running with default settings.
Well the article is for the Vero4K. But even on the Vero4K the default skin is the OSMC skin which this explanation fits
23:12:26.445 T:4082262608 INFO: Unloading old skin … 23:12:26.452 T:4082262608 INFO: load skin from: /usr/share/kodi/addons/skin.estuary (version: 1.9.16
Well that egg is firmly on my face! I have absolutely no memory of changing the skin, but I just double checked and I am indeed running Estuary. My bad!
Copy the file to a computer and try playing it using any reasonable video player (VLC, MPC-HC, what have you). If they play OK on another device, continue.
Try playing the file from local storage connected to the Vero. If you still have playback issues, continue.
Follow the instructions here to ask for help: How to submit a useful support request - General - OSMC
My issue would’ve been resolved at step 1 - it turns out the movies I had problems with were actually corrupt and needed to be replaced.
