I just bought a Asrock J4015-ITX recently and highly rate it. Does 4k fine, no HDR yet but thats a wider Linux problem. Found it even works fine with 2GB DIMMS which helped keep cost down. 2 x 4GB DIMMS seem overkill and unnecessary for LE.

Ok, more experimenting...and I think I have beaten it (or more to the point Ross Nicholson has it cracked, here: 111032 – Need to set gt_min_freq_mhz to max value to avoid sync issues on Gemini Lake N5000/J5005)

It seems this is (still) the problem. The GPU clock speed is not scaling up as it should under load.

With a NUC 2820, I added this `autostart.sh` script:

Shell-Script

1. (
2. echo 750 > /sys/devices/pci0000:00/0000:00:02.0/drm/card0/gt_min_freq_mhz
3. ) &
4. nohup script.sh &

The 750 comes from the output of this command (you should check if you have a different NUC)

Shell-Script

1. cat /sys/bus/pci/devices/0000\:00\:02.0/drm/card0/gt_max_freq_mhz

This results in immediate playback improvement - the stutter is gone from all my 25p stuff.

(I updated the bios to 68, and I am in this test using the 9.2 alpha release but it was only this specific fix that had any impact on the issue).

If I test the GPU (i.e., specifically while playing a hardware decodedc video), with

Shell-Script

1. cat /sys/bus/pci/devices/0000:00:02.0/drm/card0/gt_cur_freq_mhz

...it now shows 750 during playback (187 during the Kodi GUI still, though, which kinda surprises me but I guess the GPU is idle until playback occurs maybe?)

I shall report back if testing shows any/more issues, but I think that's a solid fix, if anyone is still following along.

Thanks for sharing. Recently bought a Gemini Lake ITX board so this is helpful.

Hi

If you plug your cable on HDMI1 you will not get the video. It's on HDMI0

OMG! Thanks this has been a PITA for the last week. Upgrade from Alpha 1 to Alpha 2 must have coincided with me changing input, couldn't for the life of me figure out why video wasn't playing after the upgrade.

Just upgraded my Pi4 from 9.1.001 to 9.1.002 and am having issues with video playback. Experiencing the issue with both offline media and TVH playback.

When I start a video I get a black screen with no video, but the audio plays. If stop the video etc I can successfully return to the Kodi menu etc.

I'm having no end of issues dumping the Kodi logs, will continue to try and extract them. This issue has only happened after the upgrade, no issues with the previous 9.1.001 install.

Is anyone able to point me in the direction of a LibreELEC image for the La Frite sbc? Or alternatively offer any insight into when/if an image might be possible?

The Libre Computer wiki links to the following site, but it errors out with a 404 erorr
