Michael Niedermayer	fd8277ffa0	Optimize bidir_refine a bit. compiled code is less tham 1/4 the size. a tiny bit faster Originally committed as revision 22777 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	a69220cce0	Change bidir refine hash code so we only need to perform a single hash calculation for the whole function. negligibly faster (about 0.1%) Originally committed as revision 22775 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	2d603902f3	Reduce the size of the bidir refine hashtable from 4096 to 256 and change the hash function to something more sane and simple. about 1/3 faster, no meassureable change in psnr or size and i gues its even same md5 with my test file but i forgot testing that.
