[x86-64] Dolby Vision a Possibility on PC?

Quote from Creator44

This is insanely good news! I wonder if the DV is "off" in the colors and brightness of it like the HDR is on my AMD mini pc though, compared to my AM6B+ ? The HDR on my AMD mini PC is not useable because it's too off and I tried everything. So I use it for SDR, especially high framerates H264 SDR which does not work correctly on AmLogic.

But yes, I can test AMD for you but I can't give the mini pc I use it with libreelec already.

I have Beelink SER8 AMD Ryzen™ 7 8845HS with AMD Radeon™ 780M 12-Core 2700 MHz model.

Yes overkill but I software decode everything on it.

Does the DV work in software decoding if you have the power?

I will be watching this thread to help you out when you make AMD builds.

Thanks a lot for your efforts!

Yes, it should work, although I don't see much practical use for software decoding when hardware decoding is available.

My DV reconstruction and rendering use the GPU standard graphics/compute pipeline through libplacebo.

I don’t plan to implement a fully SW DV renderer. The work necessary is massive to do it, and I don’t see much practical benefit. Almost every modern consumer CPU has a capable iGPU, and CPU with iGPU too weak for my current DV renderer are unlikely to have enough CPU performance to handle the same workload in the CPU anyway.

So it wouldn’t really open up many additional compatibility or use cases.

Just tried it. Unfortunately it seems it did not change anything (at all) for the 2 minute file I tested. It keeps dropping somewhat around 90+ frames in total. I even increased the power limit in the BIOS to 25w to see if it improved anything but to no effect.

As for profile 10 AV1, it plays fine with no drops at all. At least on the test file I have (Old Harrison Ford in a boat, I do not know from what movie it is). This file was already running ok on the first version you released.

As for the DV FEL All Layers Test, it is a complete failure here. It seems to render just the first frame with no colors at all and it stays frozen forever at that image (but continues to play... even after the end of the video).

Ty for your feedback, I saw two problems on the FEL reconstruction thanks to ht2tweak, a fix will be pushed tomorrow I think and hope it will fix your issue.

For later... someone asked in my YT video comments if HDR10+ is possible?

I saw that comment I think I answer directly in your video.

Yes I can add HDR10+ and I even could generate a HDR10+ render from DV metadata on the fly.
But I don't have any HDR10+ screen so it will stay theoretical.

But I will work to bake DV into HDR10, it will be not complicated since ffmpeg has all function already in place

Otherwise I pushed an update for the FEL that wasn't working it was quicker than expected, normally the test that failed should pass now, the release is R0.2.1-opt1

It was quicker than expected the new version is available on github R0.2.1-opt1 it should fix a lot of your issue with the FEL layer. https://github.com/CroqueMr/intel-dv-libreelec/releases
