can someone explain me what's different on ME method on x264
-diamond search
-hexagonal search
-uneven multi-hexagon
-exhaustive search
??
is it true that
Code:
/\
/\/\ this is 4 elements of diamond search?
\/\/
\/
/-\
| | this is 1 element of hexagon??
\_/
so diamond search will have 4 edges each element, but hexagon wil have 8 elements (each edge represent direction of search) ?
is this on x264 only? how about xvid and another codec
