Hi all, Any further comment for this single patch? This version has only changed a little compared with V4 (reviewed by Paul), which is that the check of SIMD has been moved from the wrapper function (in libswscale/x86/yuv2rgb_template.c) to format check (in libswscale/x86/yuv2rgb.c). While assembly code is exactly same with the V4. Thank you, Ting Fu. > > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > https://ffmpeg.org/mailman/listinfo/ffmpeg-devel > > To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org > with subject "unsubscribe". _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
