Hi Nuo,

since you have applied this patch (or 7/7)´today, both FATE builds on Windows
(MSVC + GCC) are failing - for all submitted patches.

https://patchwork.ffmpeg.org/project/ffmpeg


Could you please take a look?

Your CI is great!👍

😊

Should fixed by https://patchwork.ffmpeg.org/project/ffmpeg/patch/20250515124603.42691-1-nuomi2021@gmail.com/

Yup that does the trick, tanks for the quick fix.

If you could apply it quickly (it’s just affecting tests anyway), then I can try to retrigger
the failed builds for the other patches, so that they are getting proper checks results
on Patchwork.

Thanks
sw
