Regression was caused by alpha premul cleanup commit and the reason of slowdown was uchar <-> float conversion which is slow. Replaced with uchar <-> int conversion which seeps to be accurate enough and mostly eliminates slowdown. Slowdown was easy to notice when movie clip is used for 3d vierport background and undistortion is enabled. In this case every frame will re-calculate mipmaps. It's still a nit slower than mipmap generation before cleanup commit, but couldn't think about extra boost here atm. |
