[Mlt-devel] [PATCH] implement SSE optimized luma copy/scale functions

2014-06-29 Thread Maksym Veremeyenko
Hi, attached set of patches implements optimization for luma scale in matte transition, first patch change scaling equation that avoid division and only use shift and multiplication second patch implement using SSE code for scaling and copying luma. -- _
