[TESTING] Linux 4.9 kernel and improved video stack for Vero 4K / 4K +

@angry.sardine, can you give me some details? Did you use an ISO or mkv? Does the depth stay the same for each single subtitle?

Goodday Sam and team,

Just updated after last night update (26) to this mornings version 27 and i’m sorry to say that the same testfiles which include hdr give the same results, same output on screen and but this is new, no hdr anymore.

Maybe i’m to fast with updating again and you are still working on the issues, so here are my next logs

Hope it’s helpfull

With latest update (also this morning revision) when running some videos, I get a completely gray screen with sound. Here is a log : https://paste.osmc.tv/axopoxufel

I was using MKV. I think the displayed depth is consistent for any given subtitle, it’s just consistently closer to the screen than it should be. Obviously we did some testing of this a while back and the last test build I had back then, the subtitle depth matched what I get playing the original disk on my Oppo player. But now it doesn’t match - so something has changed since that last test build.

Ok, thanks. I’ve added/fixed depth support for non-pgs subtitles. Can you try and play a bit with the subtitle depth settings? I assume that the subtitle type detection doesn’t work correctly. I’ve tested here with gravity and there the depth seems to be correct.

Hi, @sam_nazarko. I see there’s another new build this morning (build 27). That seems to have fixed the crazy display corruption during 3D playback, but it hasn’t done anything for HDR output or for wired Ethernet.

I had a quick play, but it doesn’t look like the subtitle depth setting is affecting PGS subs (which is correct). PGS subs are being displayed with depth that varies from title to title (but is consistent for any one title), it’s just that the variable depth isn’t being calculated correctly.

You have a PM, by the way.

I did the update yesterday, and today is the first time I try a 4K movie. I get the same picture as you other, with vertical stripes. It wasn’t HDR videos, and but .mkv.

I now searched for a new update and installed it and I still got the same problem.

this issue introduced in build 26 is fixed in build 27. In spite of re-boots, build 26 was almost unusable for me in the TV Show browser, now it’s very snappy again. But as others have reported, 4K mkv playback is now completely broken with 27.

I have counterd just the same problem as you.
4 k striped screen. 1080 p works fine

Anyway to revert back to build 26 or 25?

My understanding is that the -26 revision of the kernel also had issues, but that is available for reinstallation via APT.

How do i do that again? just wanna test something between 26 and 27

sudo apt-get install vero364-image-4.9.113-26 --reinstall

I’m still looking in to things, to see if the kernel is actually the issue.

Keep in mind that kernel, Kodi and video firmware have to be in sync. Reverting individual packages will likely lead to more trouble.

Okay but just tested and 26 and 27 doesn’t make a difference in 4k output.
so happily waiting for a fix.

I am hoping that I can have this solved within the next day or so.

Actually, you can try updating again now. It should work better. You should use the latest kernel.

I have reverted some of the changes, and we’ll need to test them more internally before releasing further changes.

@ac16161 - I still want to know if your AVR behaves better now. If it does, I can release v18.9 to stable now for other users and then get back to work on this.

Good day,

I can confirm with your reverted version now 4k (which broke in 26/27) and hdr (broke in 27) are now correct and a bright viewable output again is visible on my tv

Is it correct the version still is on 27 or are the reverted changes just in another part and wasn’t related to the kernel?

And thanks for the prompt response in fixing this, even we are on test versions!!! Keep up the good work and stay safe.

Even though I don’t provide any logs, I did an update within OSMC one hour ago and my 4K videos still was striped.
