Yes, you could also just say that alignment is insufficient :) It is still possible to load rectangles of up to 8 columns using vlseg8e8, but it might be slower than just repeating the 8 regular loads, and it won't work if you need calculations between rows. I may be missing something but I don't understand what purpose the header file serves here? -- Rémi Denis-Courmont http://www.remlab.net/ _______________________________________________ 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".
