[x86-64] LE 12.0.1 on Intel Meteor Lake

Guessing kernel 6.11 upset it.

So the 29 September 8602b53 image fails?

Can you share the pastekodi?

Yes, I have confirmed this version.

I will share the log file, maybe tomorrow, please wait.

Sorry, the problem statement was not detailed enough.

When playing a video, there is sound output but no image output.

The “devel-20240905134548-36bff65.img.gz” version can be played normally.

After that, I tried upgrading other versions and confirmed that these versions were OK.

Hi, this is the log file, I hope it is useful to you.

**heitbaum** · October 23, 2024 at 8:58 PM New

I can see a few things.

You are using the xe driver - good (as the kernel log indicates that 4908 is not supported properly by the i915 driver.)

The Kodi gui is 4096x2160 - suggest setting this back to HD

I believe from the logs that the GUI is working - please confirm

I believe from the logs the “bootsplash” is working - please confirm

From the playback logs, you can see that koi probably picks the wrong resolution for playback of the HD stream. Use the whitelist, get it to use a HD resolution.

The stream you are playing is broken - see ffmpeg logs.

Please test a known working file. E.g. 2D BBB - http://bbb3d.renderfarming.net/download.html

I am compiling a nightly image for you to test (current master + the 6.12-rc4 linux) download from https://heitbaum.libreelec.tv - will be there shortly.

Confirmed to work.

Thanks for the new version. But it still can't be played.

https://paste.libreelec.tv/direct-arachnid.log

But 2D BBB can be played.

Then I tested the whitelist, and I added the following resolutions to the whitelist. Still no video output
4096x2160 60fps 24fps
3840x2160 60fps 24fps
1920x1080 60fps 24fps

Changing Kodi's GUI 3840x2160 or 1920x1080,The result is the same.

It's weird, all my videos can't play, but BBB can play them all.

You are forcing 3840x2160 to be scaled to 4096x2160 which is a CPU intensive task that will suck on most hardware. Please follow the config. recommendations in https://wiki.libreelec.tv/configuration/4k-hdr and with a full whitelist configured to omit the 4096 resolutions and with normal handling for 4K@25Hz, it'll probably work.

Thanks for your answer. I don't plan to upgrade.
Some versions can be used normally.
So I will use the "devel-20240905134548-36bff65" version for a while.

^ Just don't expect 25fps material to play correctly with those defined. I suggest you go read the config recommendations.

drjackel · October 26, 2024 at 12:26 AM New

sorry for hijacking my initial thread.

just a quick question on the nightly versions.

Is there a recommend one when it comes to kernel or kodi versions?

should I remain on the devel version or should I upgrade to a newer LE13 nightly?

thanks

**heitbaum** · October 26, 2024 at 1:50 AM New

Yes. Maybe. No.
Answer will depend.

In my case - I run nightly+ on my daily system (Generic ADL) , but am developing everyday as you would see. The operating system is starting to take shape for the LE13 release, in that the big changes - compilers, libraries, kernels are pretty much done. So no major changes at the operating system level that would impact are expected. We will be updating to the next Mesa soon.

As a developer, I run RC software packages, so that we try and address issues with “new packages” before they are released - thus I try to be on the front foot so that the commits are soak tested first. The team in both Kodi and LE do the same.

There are kodi changes happening (api) that will mandate changes/updates to addons, and this will continue through to the release of Kodi Piers. These may cause you to have to update - if you use these.

You will need to decide what’s best for you, but if you stay on a version “eg the early sept one” and don’t have fixed the issue you are trying to address, then when the LE13 does come out, the issue may still not be fixed in the release version. In the case of using “new hardware”, I would stay using recent nightlies, to make sure that they work with your system. Older hardware is usually more stable in the linux kernels/graphics software.

based on Chewitts answers - I would fix your system so that it can play all, as if there is another issue that comes, it might not get fixed. If there is a further problem that is not whitelist. So GUI in 1920x1080 and whitelist max 3840x2160.

Setting->player->Videos->Use HEVC VAAPI Disabeld

I disabled this item and there is no problem with CPU decoding.

I personally think there is something wrong with Intel's Linux driver.

drjackel · October 26, 2024 at 2:56 PM New

Thanks a lot for the detailed reply. I have updated to latest nightly and everything seems to work for me with xe drivers.
