NUC recommendation for 4k HDR, hi-def audio

If not, share a log from the nightly...

Please provide a full debug log.

How to post a log (wiki)

1. Enable debugging in Settings>System Settings>Logging
2. Restart Kodi
3. Replicate the problem
4. Generate a log URL (do not post/upload logs to the forum)

use "Settings > LibreELEC > System > Paste system logs" or run "pastekodi" over SSH, then post the URL link

The latest nightly does not fix it. Same issue.

Seems like the decoder doesn't like it.

A dev has replied to me. FFMPEG is capable to play the VP9 codec, but probably not the accelerated chip. Turn off hardware decoding.

The hardware supports it. It works under Windows. 10-bit VP9 HW decoding seems to be broken under Linux for all Intel chips that support 10-bit VP9 (8th gen and newer).

SMP79 reported it here after duplicating my findings: https://github.com/xbmc/xbmc/issues/23649

Thanks. I'll send the feedback back to the dev.

Can you please test with disabled hardware decoding anyway? It could also be a driver issue, not the hardware itself.

Thanks!

It looks like from smp79's discussion with Intel, the iHD driver in Linux does work to decode 10-bit VP9. It worked decoding the clip for smp79 using the Intel iHD driver for Intel via FFMPEG on the same system running LibreELEC. Whereas when using the driver through Kodi it failed. Maybe Kodi doesn't interface with the driver correctly whereas FFMPEG does?

I tested with hardware decoding disabled and it plays as expected (within the limitations of the CPU's ability to decode it fast enough).
