TSchniede,
please use merged version 1.9.5.1 as a base to prevent mess!
what is the problem with API? |
I merged my code with version 1.9.5.1. It is available
here.
It seems your selection code for 32x16 blocks got left out in PlaneOfBlocks by your merge.
I added the autodetection Dark Shikari requested. I tried adding the mc-copy, but in my tests it was as fast as default at best, so it is deactivated right now.
Boulder mentioned performance problems with my build, so I updated the VS2005 default WinAPI to 2008 and activated all performance options, it seems to be equal to your builds now.
Exhaustive search might be improved for 4xY blocks with SSSE4.1 - MPSADBW.
I was considering a few modifications to the hierarchy algorithm. As 4xY blocks are clearly slower than the larger ones, it seems advantageous to do a divide, but do a last search with the smaller blocks, that should be very close to the result of a native smaller block search.
Right now a search with 8x8 blocks, pel=1 on a 2x up sized clip is faster than a 4x4 blocks, pel=2 search.
