Release R1.0.0 RC3 · CroqueMr/libreelec-x86-DV

I've already upgraded to RC3, but I just saw your note about the FEL seeking regression and that RC3 has been withdrawn.

To be honest, I'm a bit confused now, especially with the R1.0.0-RC3 Preview release. I'm not sure which version I should be installing anymore.

Would you recommend going back to RC2 for now, staying on my current RC3 build, or installing the RC3 Preview instead?

Just want to make sure I'm using the right version until the fixes are ready. Thanks again for all your hard work.

Hi CroqueMr

I've been testing YouTube 4K60 HDR on RC3 with my Intel Core Ultra 7 255H.

AV1 hardware decoding works, and my LG TV switches to HDR mode, but Kodi reports an empty VideoPlayer.HdrType, so in Kodi's PPI show SDR.

I compared it with a regular HEVC HDR10 movie, which works perfectly and correctly reports hdr10.

I also noticed that VP9 HDR gives me a black screen with VAAPI enabled. Disabling VP9 VAAPI fixes the picture, but I'd prefer to keep hardware decoding enabled.

Could you look into the AV1 HDR metadata reporting and VP9 VAAPI playback on Intel?

I have logs and screenshots if needed. Thanks.

me too I tested the file broken.

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.

Quote from CroqueMr

FYI : From now on, I'll gradually add fixes and features to the next build. Once enough changes have accumulated, I'll clean up the code, optimize everything, and push a new release.

The RC3 preview is already available here https://github.com/CroqueMr/libre…0.0-RC3-Preview

Great work, CroqueMr! 👏

Thank you for releasing RC3 Preview and for all the effort you're putting into this project. It's great to see the continued improvements, especially with Dolby Vision FEL and Blu-ray menu support.

I'm looking forward to testing this release on my Intel Arc NUC and will share my feedback after trying it with different movies and Blu-ray ISOs.

I also found the updated JRE add-on in the release assets.

Thanks again for your dedication and hard work. Really appreciate it! 👍

R1.0.0 RC2 - Stability improvement, HDR10+ fixes, BD-J Menu experimental support

Hi CroqueMr.

First of all, a huge thank you for all the amazing work you've put into RC2!

I'm really happy to see that you've added experimental Blu-ray HDMV and BD-J menu support. This is something I've been hoping to see for quite a while, especially with my large collection of Blu-ray ISOs. I really appreciate you taking the time to work on it!

And I've got some exciting news! My new ASUS NUC 15 Pro AI Mini PC with an Intel Core Ultra 7 255H and Intel Arc graphics has finally arrived! 😍

I'm really excited to test RC2 on this new machine, especially Dolby Vision FEL, 4K60 playback, full Blu-ray ISO menus, picture quality, and overall system performance and stability.

Once I've spent some time testing everything, I'll be happy to share my experience and feedback with you, including any issues I might come across.

RC1.1 was already fantastic in my experience, so I'm really looking forward to seeing what RC2 brings, especially with all the new improvements and Blu-ray support!

Thanks again, my friend, for your dedication, patience, and all the effort you've put into this project. It's truly impressive how far your build has come, and I really appreciate everything you're doing for the community.

Keep up the fantastic work. 🌹👏

not surprised it's smoother


CPU: Intel Core i9-13900K

• GPU: NVIDIA RTX 5090

damn you threw the whole kitchen at this. your hardware wouldn't even notice the GPU work for this. it's good to see Kodi is not restricted anymore. this will attract allot more to x86 and maybe more development as a result and plus 1 to what Vertox wrote. CroqueMr work has put him in legendary status.

Haha, thanks for the kind words! 😄

Just a small clarification: my testing of RC1.1, including Gemini Man 4K 60fps Dolby Vision FEL and Billy Lynn's Long Halftime Walk 4K 60fps HDR10, was actually done on my ASUS Mini PC with an Intel Core i7-1360P and integrated Iris Xe graphics, not the RTX 5090!

That's what makes the results even more impressive to me. Seeing such smooth playback without dropped frames on integrated graphics really shows how much progress CroqueMr has made with this build.

I completely agree with you. His work is truly amazing, and he deserves all the recognition he's getting! 🌹👏

CroqueMr

Hi, Just wanted to share some really great feedback after spending more time with R1.0.0 RC1.1.

Honestly, this is by far the best experience I've had with your build!

I've been testing several movies, including some that were particularly demanding in previous releases, and the results have been fantastic.

Gemini Man (4K 60fps Dolby Vision FEL) was always one of my toughest tests, with dropped frames in earlier builds. But for the first time, I'm now seeing no dropped frames during my playback tests! That's a huge improvement!

I also tested Billy Lynn's Long Halftime Walk (4K 60fps HDR10), and it played beautifully without any dropped frames either.

And it's not just these two movies. I've tested several other titles as well, and so far, playback has been incredibly smooth across everything I've tried.

The picture quality on my LG G6 is absolutely gorgeous. Dolby Vision FEL looks fantastic, HDR10 looks excellent too, and I'm really impressed with the overall presentation.

Another thing I've noticed is how fast and responsive Kodi feels. Navigating through menus, browsing my movie library, and switching between different sections is noticeably smoother and quicker. The whole system feels much more polished now.

What makes this release special for me is the combination of excellent picture quality, smooth playback, and overall system responsiveness. It's exactly the kind of experience I've been hoping for since I first started testing your builds.

So far, RC1.1 has been running beautifully without a single issue in my testing. I'm really enjoying RC1.1, and it's been an absolute pleasure using it for my everyday movie watching!

I'll continue using it and report back if I notice anything unusual, but right now, I just wanted to share some positive feedback because I think you really deserve it.

Thank you so much, CroqueMr, for your dedication, patience, and all the hard work you've put into this project. The progress has been incredible, and it's genuinely a pleasure to use your build every day.

Fantastic work, my friend! 🌹👏

LibreELEC Hades 1.0 RC5 is out

Hi hadesdevls,

Thanks again for all your hard work on Hades.

Just wanted to report an issue I've been having with native Dolby Vision on my RTX 5090 since RC3. Unfortunately, the same problem is still present in RC4 and the latest RC5.

Every Dolby Vision movie I've tried plays in HDR10 instead of Dolby Vision.

My main PC:

• CPU: Intel Core i9-13900K
• GPU: NVIDIA RTX 5090
• Display: LG OLED G6 (TV-Led Dolby Vision)
• Build: LibreELEC Hades 1.0 RC5

Native Dolby Vision output is enabled, and Low-Latency Dolby Vision is disabled.

I've also tested both transport options, As licensed players send (IPT) and As composed, but neither made a difference. The TV still switches to HDR10.

I checked the Kodi logs and found this:

Dolby Vision detection:

Dolby Vision profile 7 level 9
RPU: yes, enhancement layer: yes, base layer: yes

Main error:

DVBridge: native Dolby Vision output unavailable: the display does not advertise Dolby Vision Standard

Actual output:

HDR output: HDR10 goes out at 10 bits in 3840x2160 @ 59.940 Hz

Here's something interesting I discovered today:

I installed the same Hades RC5 build on my ASUS Mini PC with an Intel Core i7-1360P and Iris Xe graphics, connected to the same LG G6, and Dolby Vision FEL works perfectly without any issues!

So RC5 works great with Intel Iris Xe, but native Dolby Vision still won't activate on my RTX 5090.

I've also previously had native Dolby Vision working on the RTX 5090 using another custom LibreELEC build, so it seems this might be something specific to the NVIDIA output or Dolby Vision detection path in Hades.

Since the issue has been there since RC3, could you please take a look when you get a chance?

I've attached a diagnostic log with the relevant details. Hopefully, it helps narrow things down.

Thanks again for all your efforts. Really appreciate everything you're doing with this project.

Vertox thanks a lot! An RTX 5090 and an Iris Xe mini PC are a great pair to try it on, they cover both ends. If anything looks off, tick "Save diagnostics" in the installer and attach the hades-diag folder to an issue; it already filters out personal details.

One heads-up for the mini PC: if its TV takes HDR10+ but not Dolby Vision, leave "Send it as HDR10+" off for now. On Intel at 4K 23.976 it falls back to HDR10, and the fix comes in the next version.

Thanks for the heads-up. Just to let you know, my display is an LG G6, so it natively supports Dolby Vision and isn't limited to HDR10+ only. I'll make sure to attach the hades-diag logs if anything acts up. Keep up the awesome work

LibreELEC Hades 1.0 RC4 is out:
https://github.com/hadesdevls/Lib…es/tag/v1.0-rc4

Haha, two new releases on the same day! What a nice surprise! 😄

Big thanks to you too, hadesdevls! It's great to see how much progress you're making with this project, especially with NVIDIA support and FEL playback.

I'll definitely be giving RC4 a try as well, particularly on my PC RTX 5090 and Mini PC with Intel Iris Xe graphics. Really curious to see how everything performs with the latest improvements.

Much respect to both you and CroqueMr for all the time and effort you're putting into these builds. It's great to have two excellent projects to test and enjoy.

Keep up the great work.

Repo will be updated later but release is up

R1.0.0 RC1 - Performance improvements, DV-to-HDR10+ and wider hardware support

Wow, RC1 is finally here! 😄

Thanks a lot, CroqueMr, for all the hard work you've put into this project. Really appreciate the time and effort you've spent improving things and listening to everyone's feedback.

I'm really looking forward to trying RC1, especially the FEL improvements and the playback fixes. I'll be testing your new build and sharing my feedback if I come across anything.

Great work as always, and thanks again for keeping this project moving forward.👍

Quote from CroqueMr

Very complicated. I already have a DV-to-HDR10 mode that works somewhat like LLDV, but outputs HDR10. Of course this mode is not a real DV output but it manages the more important DV adjustment.

However, doing true LLDV would require significantly more processing power on the PC side. It would only be feasible on much more powerful hardware, or with some massive optimizations that I honestly have no idea how to pull off without impacting image quality.

Just wondering, would it be possible to add an option to convert SDR to Dolby Vision and HDR10 to Dolby Vision, similar to what CoreELEC offers?

It would be great to have these as optional features so we can enable or disable them whenever we want, while keeping native playback as the default.

Not sure how difficult this would be to implement, but I'd love to see it in a future build.

Thanks again for all your hard work. We're really looking forward to the next release and can't wait to test it and see what's new!

K23 will indirectly solve that kind of thing (and likely confuse people):

https://github.com/user-attachmen…3f-2a834a93145f

Really interesting to see what’s coming in K23. I personally prefer keeping the original aspect ratio without cropping or stretching the image. Just curious, will these changes also improve subtitle positioning, especially when switching between different aspect ratios?

Hi, I'm having a problem connecting to your LibreELEC-Hades build using FileZilla on Windows. I'm using SFTP (SSH File Transfer Protocol) with the username root, but the connection keeps getting rejected.

The same FileZilla setup works perfectly with CroqueMr's LibreELEC build, so I'm not sure what's different here. I also tried changing the SSH password through the LibreELEC settings, but that didn't help.

Is SFTP supported in your build, or is there something else I need to enable?

I also have one question about the RC3 release. I noticed this file:

LibreELEC-Hades-1.0-RC3-firmware-and-nvidia.tar

I'm not sure what it's meant for. Is it an update package, or does it need to be installed separately? Is it specifically for systems with NVIDIA GPUs? I'm using an RTX 5090, so I'd appreciate some guidance on how to use it.

Thanks again for your help and all the effort you're putting into this project.

Quote from CroqueMr

Thanks for the feedback, for the GUI that generate drops it's a known issue, many GPU can not handle FEL + GUI. In master reference mode I don't think I will be able to patch it completely. This mode is VERY restrictive, if any modification change the picture by one bit, even if it's invisible the mod is rejected. But I see one small issue, it may reduce the drops. I will push a debug2 later today.

Thanks for the explanation, I understand the limitations of Master Reference mode, and I'd definitely prefer to keep the picture quality intact. I'll test Debug2 when it's available and let you know if the frame drops improve. Really appreciate your work.

Hi CroqueMr,

First of all, thank you again for your continued work on LibreELEC Dolby Vision. I really appreciate the time and effort you're putting into this project.

I've been testing R1.0.0-Beta4-debug with the following setup:

• Device: ASUS Mini PC
• CPU: Intel Core i7-1360P
• GPU: Intel Iris Xe

I've noticed an issue with Dolby Vision Profile 7 FEL playback.

Whenever I press O to display or cycle through the player information, frames start dropping. The more I press O, the higher the dropped-frame counter gets.

I've reproduced this with:

• Dolby Vision Profile 7 FEL MKV files.
• Dolby Vision FEL Blu-ray ISO files.
• FEL content running at 59.94/60fps.

For example, while testing Gemini Man, the dropped-frame counter reached 48 in one screenshot and 151 in another.

What's interesting is that HDR10 playback works smoothly on the same Intel hardware, even at 59.94/60fps. I tested Billy Lynn's Long Halftime Walk in HDR10, and it showed 0 dropped frames and only 1 skipped frame.

I also tested Heretic in Dolby Vision Profile 7, and the player information confirmed:

• FEL reconstructed: Full FEL
• FEL upscaling: Reference GPU
• Dolby Vision Master Reference
• TV-Led Dolby Vision tunnel

I've attached screenshots showing the difference between FEL and HDR10, along with Kodi log containing the relevant DVBridge and CB1 rendering diagnostics.

I understand that the debug build may introduce additional playback stalls, so these results aren't intended as a performance benchmark. However, the difference between FEL and HDR10 when opening the player information overlay seems worth investigating.

Could you please take a look when you have time? I'm wondering whether displaying the player information overlay adds extra rendering overhead during FEL playback on Intel GPUs.

Thanks again for all your hard work. I really appreciate it.
