The aligned attribute does not work reliably with stack variables in some cases. Compare with other code, I think you need to use LOCAL_ALIGNED_16 for the stack variable. Yes, it might work in your test even with DECLARE_ALIGNED, but it might not be robust. _______________________________________________ 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".
