@asmorkalov Thank you to cc for me!

The libjpeg-turbo version should be increment from v3.1.0 to v3.1.2

https://github.com/opencv/opencv/actions/runs/19825631804/job/56915434214?pr=28112#step:6:688

  --   Media I/O: 
  --     ZLib:                        build (ver 1.3.1)
  --     JPEG:                        build-libjpeg-turbo (ver 3.1.0-70)
  --       SIMD Support Request:      YES
  --       SIMD Support:              NO

libjpeg-turbo is here

https://github.com/libjpeg-turbo/libjpeg-turbo/blob/4e151a4ad91001b3aa8c2ece2205c15f487ce320/CMakeLists.txt#L17-L19

project(libjpeg-turbo C)
set(VERSION 3.1.2)
set(COPYRIGHT_YEAR "1991-2025")
string(REPLACE "." ";" VERSION_TRIPLET ${VERSION})

OpenCV source is here.

opencv/3rdparty/libjpeg-turbo/CMakeLists.txt

Lines 21 to 23 in a085652

set(VERSION 3.1.0)
set(COPYRIGHT_YEAR "1991-2024")
string(REPLACE "." ";" VERSION_TRIPLET ${VERSION})

It is better to update libjpeg-turbo version with this PR togeter I think.

- set(VERSION 3.1.0)
+ set(VERSION 3.1.2)
- set(COPYRIGHT_YEAR "1991-2024")
+ set(COPYRIGHT_YEAR "1991-2025")
  string(REPLACE "." ";" VERSION_TRIPLET ${VERSION})
