  • [x86-64] HDR Playback

    I just tried the latest nightly with my Ryzen GMKTEK M6 Ultra. I have the same issues as reported, the gui is always perfect. However sometimes when i start a movie the colors in HDR are washed out, i have to stop and restart then its fine.

    On a side note. I’ve noticed a bug when using AMD. It doesn’t always apply the correct color. Sometimes it appears washed out. If I stop and restart it usually fixes it.

    I think this has been mentioned before. I’ve tried limiting it to 4:2:0 but doesn’t solve the problem.

  • Nightly Builds

    Just FYI for anyone, I've been trying the latest builds on a N150 platform and a AMD Ryzen 5 7640HS that has the Radeon 760M GPU. I have it connected to a Lumagen processor and JVC NZ900 projector. The N150 outputs RGB and the Radeon output YUV:444.

    My lumagen and projector is professionally calibrated by an ISF certified calibrator. We have noticed that the N150 with its output as RGB crushes the blacks slightly. However the Radeon 760M with YUV outputs correctly. We tried all types of material and both agreed the AMD was better. We compared the output to the Kaleidascape Strato player and the Radeon output matches the Kaleidascape. The Intel crushes the blacks.

    Also of note if we play a 4K60 file that is HDR the Lumagen doesn't like the output in RGB. The Radeon outputs it correctly as YUV:420 4k60 which matches the Kaleidascape Player we tried.

    I believe it might be because YUV limits the range to 16-235 where RGB is 0-255

    Just for thought. Someone might find this post useful.


    UPDATE: Looks like it’s a lumagen issue. Disregard 🤣

  • Generic LE13 nightly after 2026-05-17 needs 1GB boot partition

    At the current time "you get output" .. what bit-depth, colourspace and colour-range I've no idea. It's probably not brilliant as we're forced to use the elFarto VAAPI shim until Kodi gains NVDEC support. There are also quite a few things to unwind/redo in Kodi's EGL rendering path to resolve. The x86 world is oriented towards RGB rather than YUV but this isn't an issue as long as things are being done right, i.e. fixing some of the limited/full range issues in the display chain; which is actively being worked on. So no advantages over Intel/AMD that I can see (both suffer from some of the same RGB issues) and I'd still advise anyone considering new purchases to avoid nVidia cards until more of the plumbing has been straightened out.

    NB: Support for nVidia now means only GPU's that can use the 580.xx driver series; and we've intentionally held off bumping to the latest driver because that orphans eveything before RTX cards. Current stats show nVidia tiny user numbers on the 580.xx driver, though to be fair we have been telling users to avoid nVidia cards for the last decade so there's an element of "built it and they will come" in-play. I'd expect numbers to increase once there is clear direction on support.

    Thanks for the reply. I am currently running a N150 and its output is obviously RGB. However its plugged into a Lumagen and it prefers YUV. I would prefer YUV does AMD output that? Or are we generally stuck with RGB for now.

  • Generic LE13 nightly after 2026-05-17 needs 1GB boot partition

    The default boot partition was enlarged from 512MB > 1GB last year to accomodate nVidia driver increases over time, and Generic now (since yesterday) supports current nVidia GPU cards hence the sudden size increase.

    The fastest workaround is to use the backup function in the settings add-on (captures /storage/.cache|.config|.kodi) and move that off box, reinstall to create a clean instance with larger boot partition, then restore the backup. Beware anything outside of those ^ folders that you also want to preserve. Resizing partitions can also be done using e.g. Gparted on an Ubuntu LiveUSB, but it will be significantly slower (10x slower if not more).

    With support of current Nvidia GPU's now enabled. What are the benefits over Intel GPU? Can nvidia offer YUV ouput instead of RGB?

  • [x86-64] Best LE 13 Nightly for Intel N150 (Alder Lake-N)

    Add to above, i have refresh rate switch turned on etc. If i have the Kodi menu at 1080p60p a 24p 4k file will not output at 4k but 1080p. A 4k23.98 file will output at 4k however as it should.

    If i change kodi menu to 4k60p the 4k24p file will output as it should 4k24p, and a 4k23.98 file will output correctly.

    This also occurs if i install windows and Kodi. Its got me stumped lol

  • [x86-64] Best LE 13 Nightly for Intel N150 (Alder Lake-N)

    I have a N150, i have an issue where any 4k file that is 24p (not 23.98) is output as 1080p24p not 3840p24p. I've tried different TV's both do the same. I've tried coreelec on a odroid n2 which outputs correctly. Both the odroid and N150 formatted and setup identically but the N150 always outputs 1080p24p files at 1080p24p. Not at 4k. However 23.98 files are fine and outputted correctly.

    Everything points to the N150 and libreelec. I've tried 12.2 and nightly releases. Any ideas?

  • [x86-64] How to force YUV 4:4:4?

    This works perfect, i have to use the 10-bit option otherwise i get dropouts.

    However i noticed that the video output refresh rate is 23.95, not 23.976 which creates stutters. Any ideas?
