Please revert any changes in simde, that’s a dependency. Feel free to fix those issues upstream.

[luzpaz]

@gxalpha any chance you can help me figure out where upstream is ? I did a search in the code and github and couldn't locate.

[gxalpha]

https://github.com/simd-everywhere/simde, but it looks like they're already fixed. simde has already been included in obs-deps and will at some point be used from there (and removed from this repo, see e.g.#10961), so there is nothing to fix in that regard.

[RytoEX]

Please note that #11166 covers these changes already.

[luzpaz]

Indeed. it's only missing:
https://github.com/obsproject/obs-studio/pull/11740/files#diff-a842cfba79abe99602c314f3d99b8acfe55ea8efc0a058cf098a852eecd11ab3

@umlaeute do you want to cherry-pick that ?

[umlaeute]

i'm not sure what I should cherry pick. all three changes of your 672afcb seem to be already in my 453c3ac.
so what am I missing?

[luzpaz]

I'm on my phone and can't confirm. If you say so, then I'll close this PR.
