bug: HW Accelerated HEVC decoding leading to inaccurate colors being displayed

[ThaUnknown]

System Details

• OS: Windows 10 21H2
• Thorium Version M106.0.5237.0

Problem
HEVC Videos inaccurately calculate their color profiles leading to color inaccuracy, or simply making the video look more washed out than it actually is.

Right: expected

Additional Notes
For comparison I used Muril's patch which doesn't enable hardware accelerated HEVC decoding for this very reason. This issue is effectively asking to stop using StaZhu's patch and instead switch to Muril's patch, which also includes EAC-3/AC-3

@ThaUnknown Thanks, I will look into it.

@ThaUnknown Updated ffmpeg patch and made minor adjustment. It should play HEVC with software decoding now, which is good for everyone, but it also might have resolved your color issue. Can you test latest release?

@Alex313031 seems this was fixed in StaZhu's patches, I don't know exactly when as I wasn't keeping a pulse on this.

[Alex313031]

@ThaUnknown Cool.

@gz83 close test
