[x86-64][CroqueMr Builds] Dolby Vision w/FEL, HDR10+, and 3D

  • Thank you so much for your work. Ive tried RC2 on a rtx 3080 and it works pretty well except that the player freezes when i bring up the dv mode screen (double pressing O). That is on a fel movie, mel doesnt have it. Also black screen after closing a video but i think it can be my hdmi cable.

    Please send me the log, and could you try the RC3 preview and tel me if you have the issue?

  • ashlar how that NUC performs?

    It's fine. Were it not for the problems I describe, from what I've seen it would work great to watch a movie at top quality. Due to the problems, I'm not using it as a daily driver (yet?). But, performance wise, it looks to be up to the task (it's a more powerful than the baseline N100 that's been targeted).

    I think I might know the culprit now that makes the start-ups sporadic (not impossible, but sporadic)

    It seems like LibreELEC get hung up on my dedicated PCI soundcard. I have disconnected it and now the start-ups are consistent.

    Both versions show now zero problems with starting, since I removed the PCI soundcard.


    CroqueMr the problem with the Wifi mouse and keyboard extend to your version too sadly.

    For some reason with LibreELEC the distance to where they both work away from their USB-dongles is severely reduced compared to Windows 11. I have to put the mouse like 1-2 meters close to the dongle for it to work fine in LE, any idea why that could be?

    One is for the Keychron M5 8K
    and the other is for a generic cheap Rii keyboard
    Both are used with their Wifi signal.

    P.S. Oh and also the mouse worked pretty fine(not great but fine) in the setup menu in the beginning of the very first start, but as soon as it's in the main menu the outages begin.

    Edit: could it be that the USB dongle or devices in general are being run in some low powered mode to save energy or something?

  • absolutely incredible work.. the only thing missing now would be an equalizer apo method to implement better filters and not be limited by audio systems, or if someone as talented as you could pitch in to implement something similar it would probably be the most breaking thing ever.

    keep up the amazing work, absolutely stellar work

  • the only thing missing now would be an equalizer apo method to implement better filters and not be limited by audio systems

    We already had that equalizer discussion. In short, an A/V stream is like a heavy train. If you want to change something inside of a wagon, you have to stop the whole train. Not a good idea (buffer size, CPU/GPU speed etc.).

  • I've been testing HDR10 Expert on a Samsung S95H (TV peak set to 2600, static tone mapping) with the CroqueMr RC3 build on a 780M box, and a few DV titles look wrong:
    - The Shining: washed out, especially the opening aerial shots.
    - Ocean's Eleven: black crush in darker scenes.

    Switching to HDR10 Basic (or native Kodi) fixes both. Can anyone else reproduce this?

    I had Claude Code go at it with a private build and some additional debug logging, don't know if it's on to something or not:

    Expert applies the CM2.9 L2 slope/offset/power in linear nits normalised to the TV peak: T * clamp(in/T * slope + offset)^power. Because the offset is multiplied by T, a tiny trim becomes a big black-level shift at high peaks:

    ┌────────────────┬───────────┬─────────────────────────────────────────────┐
    │ title │ L2 offset │ effect at T = 2600 │
    ├────────────────┼───────────┼─────────────────────────────────────────────┤
    │ The Shining │ +0.0033 │ +8.6-nit black floor (washed out) │
    ├────────────────┼───────────┼─────────────────────────────────────────────┤
    │ Ocean's Eleven │ −0.0006 │ everything below ~1.6 nits crushed to black │
    └────────────────┴───────────┴─────────────────────────────────────────────┘

    (Offsets are the values CB1 resolved for a 2600-nit target, offset = code/4096 − 0.5; e.g. code 2061.5 → +0.0033.)

    With nothing changed except skipping the L2 trim step, both titles looked normal. With trims applied they were washed out or crushed.

  • Greetings, everyone. Could someone share a working setup for running Windows 11 in a virtual machine—one that allows for full project functionality while enabling the use of the AMD 9950’s integrated graphics core, even when the system is running on a discrete graphics card? I would be very grateful. I’m sure this topic is of interest to many others here on the forum. And a huge thank you to the developer for all their hard work!!!

  • Thanks for the feedbacks, I am working on a more precise conversion a real LLDV over HDR10, it will replace HDR expert conversion at target.

  • Khazar I've been experimenting similar issues with Nvidia SHIELD Remote, connected by bluetooth with an excellent range in my case, since my Asrock B660 ITX/AC uses antennas for both wifi and bluetooth. In my particular case, the remote pairs but then, it disconnet and connect continously, without any pattern, it's imposible is a problem with any kind of suspend mode y continuosly click buttons on the remote.

    I also tried with a ASUS dongle to discard a incompatibility of the Asrock mother board Intel controller. No luck, same problem.

    NVIDIA SHIELD Remote is particulary interesting since it integrates a IR too, so I can make volume on my a/v receptor works at the same time bluetooth works for the rest, you need SHIELD also to first programm that.

    I'm desesperante with theee disconnetions.

  • Hi CroqueMr

    Just a quick heads-up: I've opened a bug report on GitHub about Dolby Vision Master Reference (IPT-PQc2) failing to start playback on my Intel Arc NUC with RC3 Update 5.

    The same movie plays fine when I switch to Dolby Vision Reference. I've included logs from both the failed and successful attempts so you can compare them.

    Thanks again for all your work! Really appreciate it.

    I was looking into this, but AFAIK it's not possible under Windows 11. You need a hypervisor that can do Direct Device Assignment (DDA), but the Windows 11 version of Hyper-V does not support that. You would need to run Windows Server Datacenter Edition for that. Maybe there is anther hypervisor that can do this under Windows 11, but I haven't found it yet.

  • I found this fork last Sunday and tried RC3 on an i3-14100 iGPU (2x4 GB DDR4-2133) + LG G4 and it works fantastic. I only have a handful of Dolby Vision rips (no FEL) but they all play with very little render utilization using Auto scaling (~25% shown on info OSD with DV Reference at 23.976 Hz). I never hoped to have DV from a PC, but here we are. :)

    Also tried DV to HDR10 which is also excellent. I could not really spot much difference with the naked eye compared to native DV and the image was miles better than the overblown contrast and colors of Kodi HDR10 fallback.

    Thank you CroqueMr for this insane work.

  • I wanted to watch "Saving Private Ryan", but it won't play. It’s stuck on a single static frame.

    Could it be an issue with the Ryzen 5 7430U? Tested on CroqueMr R1.0.0-RC3. Perhaps you could try it on an Intel-based system?
