HDR on x86 Hardware

    Quote from smp

    I think this has something to do with how the realtime streams are handled by Kodi.

    Could you try to play via pvr addon with this build? - LibreELEC-Generic.x86_64-12.0-devel-20231208072228-5b2d3ec.img.gz

    this build active HLG for pvr addon except one channel audio work but black screen

    and play recorder from this channel HLG working!

    here sample rec HLG https://file.io/uFsO1LM4dnIj


    here display-info

    and meta sample HLG file:

    (Posting here because of mentions of refresh rate).

    I'm using LE 12 nightly generic 20231206 on Intel HD630. HDR is working on my Sony.

    I have an intermittent sync problem for pretty much every refresh rate/resolution combo. I think start of sync doesn't get reset to topleft when refresh rate changes. Not only when playing but also regular UI.

    Is this a known issue?

    i try use same stream via "iptv simple client" addon and video hlg work!

    so i think issue in pvr "dvbviewer" addon

    I do not know why?

    I noticed this as well, but only on my newer Sony TV. My LG oled & A company that starts with an 'E' projector (I don't know why that is censored here) don't have the issue. I downgraded back to this build and the issue went away: nightly-20231103-a581fc8

    I found a fix. My whitelist was empty when I posted the first time and so I got a lot of these weird screen misallignments. Then I threw every resolution my Sony could handle in the whitelist. I still had weirdness but LESS...

    So the fix was to leave everything in the whitelist except for resolutions with 24 and 23,98 fps. Kodi now transforms a source with 24 and 23,98 to for example 25 or 60 fps which play fine.

    I always used a Nvidia Shield before so the past few days I had to find my way with x86. I now sometimes have for example active deinterlacing active while playing, that's a blast from the past.

    Can some point me to nexus version that work well with PVR, without issue of flickering
    This version LibreELEC-Generic.x86_64-11.0-devel-20230312065957-84d83d1.img.gz, but its for Kodi 21 Beta 1

    Thanks

    Thanks sky42 for your bt2020 builds... It's a little misleading to have 'HDR now supported under intel & amd' in the 11.0.4 release notes when the official builds don't trigger the bt.2020 colorspace, effectively making the HDR mode useless (although it does trigger HDR mode) *shrug*

    Should drm prime work with NUC7 Gemini Lake? (NUC7PJYH2) I get audio but no video output when drm prime is activated.


    I see the following error messages when drm prime is activated

    wondering if we could disable this option at the kodi gui as it just creates problems ?

    IMO this should be done upstream in Kodi, e.g. if platform supports VAAPI then DRM PRIME option should not be present in GUI.

    Good morning I have a problem on a nuc7i3 with LibreELEC 11.0.6 I have set everything as in previous versions and with a celeron nuc, now I can watch 4k on Samsung TV the problem arises when I go from the very well contrasted start screen to the film which results with a much lighter black. What did I do wrong or do I have to enter a string in advancedsettings to make the contrasts work. Thank you

    Hey folks, one question - do I get correctly that HDR is not supported on Legacy x86-64 builds? I have to use legacy due to the fact that I want Moonlight client to function correctly and it doesn't seem to work without X.org

    Yes, X.org doesn't support HDR.

    EDIT : going to post this in debug


    Green HDR image on AMD RX550

    Libreelec 12 latest nightly-generic on AMD RX550 2GB via hdmi 2.0. Cables and tv work with HDR no problem on another Libreelec box with AMD APU, also LE nightly-generic.

    Logfile : first I play a HDR10 file with green image as below. Then I play a testfile from Kodi-samples with HDR10 bt2020, colors are okay but no hdr.
