Hi Ronald, I didn't make the decision single-handedly, do not, and will not do. I just followed the suggestions from the maintainers of FFmpeg. I think you might be able to check more details follow these three archived links: http://ffmpeg.org/pipermail/ffmpeg-devel/2021-August/283869.html http://ffmpeg.org/pipermail/ffmpeg-devel/2021-August/283878.html http://ffmpeg.org/pipermail/ffmpeg-devel/2021-August/283872.html And about the runtime check of cpuid, I have updated the v2 patches today. Please check this for more details. http://ffmpeg.org/pipermail/ffmpeg-devel/2021-August/283973.html It seemed that there are different perspectives from maintainers of the community. And I was supposed to clarify here that I follow the FFmpeg contribution checklist and use the AVX512 invoking conventions in libavutil/cpu in FFmpeg to submit a patchset about optimization Gaussian Blur with AVX2 and AVX512. And I have been actively communicating and accepting the suggestions from the mail-list to fix and improve what I could do for the patches. By the way, I have emphasized that using AVX512 is not mandatory at the beginning. Use or not depends on users and developers. The options that disable and enable AVX512 have already been provided by FFmpeg. Here are more details: http://ffmpeg.org/pipermail/ffmpeg-devel/2021-August/283587.html So what should I do? Feel free to let me know. Best regards.
