Thanks for the help. I'm not familiar with WIN64 asm. So what I need to do is change the WIN64 swap from: SWAP xmm0, xmm2 SWAP xmm1, xmm3 To: VBROADCASTSS m0, xmm2 VBROADCASTSS m1, xmm3 Is that correct? _______________________________________________ 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".
