1831132 - Color management not working on videos

Status: UNCONFIRMED

(Core :: Graphics: Color Management, defect)

Description

[Peter]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/112.0

Steps to reproduce:

• Set following about:config settings:
  • gfx.color_management.display_profile to profile of monitor (I use this profile from rtings.com)
  • gfx.color_management.mode to 1 (Full color management)
  • gfx.color_management.rendering_intent to 3 (ICC-Absolute colorimetric)
• Open any YouTube video. This might be a good choice.

Actual results:

Video is oversaturated, matching the wide-gamut images instead of sRGB.

Expected results:

In ideal world, color profile used to encode video (bt709 according to YouTube) should be used. If that's not possible/available, than sRGB should be assumed, same as with untagged images or CSS elements.

Link to a website I used as an reference for how the color should look like: https://www.wide-gamut.com/test
