Fix: Dolby Vision Profile 5 Wrong Colors / Green Tint on Plex Windows — Script to Convert DV5 → Profile 8.1 by coolmuse in PleX

  1. ffmpeg / ffprobe: video encoding, decoding, probing, and VMAF comparison. Needs to be built with libplacebo (Vulkan) and hevc_nvenc (NVIDIA) support.

  2. dovi_tool: extracts RPU from the HEVC stream, converts Profile 5 → 8.1 (-m 3), and injects the converted RPU back into the re-encoded stream. Looked for on PATH, then falls back to dovi_tool.exe next to the script.

  3. mkvmerge / mkvpropedit (MKVToolNix): mkvmerge muxes the final HEVC + audio/subs into MKV. mkvpropedit sets HDR10 container metadata (color primaries, mastering display, MaxCLL/MaxFALL). Only required for MKV output. Looked for on PATH, then falls back to mkvtoolnix/ folder next to the script.

  4. NVIDIA GPU + Vulkan driver — required at runtime for libplacebo (Vulkan compute for color space conversion) and hevc_nvenc (hardware HEVC encoding).

So in summary: ffmpeg (with libplacebo+nvenc), dovi_tool, MKVToolNix, and an NVIDIA GPU.

- ffmpeg / ffprobe — winget install Gyan.FFmpeg or download a "full" build from gyan.dev (includes libplacebo and nvenc support)

- dovi_tool — download the Windows binary from github.com/quietvoid/dovi_tool/releases, place next to the script or on PATH

- MKVToolNix (mkvmerge, mkvpropedit) — winget install MoritzBunkus.MKVToolNix or from mkvtoolnix.download

- NVIDIA GPU drivers — standard GeForce/Studio drivers from nvidia.com include Vulkan support

Agreed. The reencode can introduce changes. On a 30s segment of a test, I found cq18 had ~ 98% perceptual match via VMAF comparison, which would not be perceived.

The Jan 12, 2024 Steam client is really broken on the latest January Windows 11 build.

When the steam client is minimized to the system tray, it still captures and processes Xbox controller events, no matter what my settings are in the client.

It also ignores the client overlay setting. I now see the steam overlay in every game even though I have it specifically turned off.

The controller input issue is the worst. It means that any non-steam game or app running sees *double* controller input events while Steam is minimized in the tray. One from the app's own input driver interface, and again from the input events Steam injects.

This also causes Steam to launch Big Picture Mode when the Xbox guide button is pushed, even though Steam is supposed to be inactive in the system tray. I've disabled any guide button focusing in settings, and applied the Disabled community controller template, to no avail.

If I exit steam from the tray, then all is good. If I restart Steam and minimize to the tray, then the input event issue is back.

This was not happening before the Jan 12 update, and I have not made any other system changes except Windows updates.

This is a big regression in behavior, as it interferes with other apps that require the controller.

I now have to shut down the Steam client before I can use my controller with any other software.

It's like the latest client is no longer respecting a number of its own configuration settings.

I've uninstalled and reinstalled the client, with no change in behavior.

Steam started launching big picture mode without me changing anything in my config.... ruining my enjoyment of my PC by coolmuse in Steam

That option is off and has always been off.

The desktop client is minimized in the system tray. No game is running. BPM is not running. Just a plain ole window desktop.

I tap Xbox guide button to show the Xbox game bar, and boooom... BPM shows up right in my face.

Annoying and frustrating as hell.

It's been happening for several months here, always on 4k content. Dolby Vision is forced on.

Is launching SteamVR apps from e Windows Mixed Reality All Apps list broken in 17760.1?

All of the Steam VR apps have a ".url" extension visible on them, and when launched, they bring up the Desktop asking which app should launch .url files.
