Michael Niedermayer	7d7f57d939	store halfpel filter coefficients in the header as well as the flag for diagonal interpolation the primary reason for this change is that previously MC up to 1/4 pel matched H.264 exactly and that increases the risk of stumbling over patents secondly this allows 0.10 db or more quality gain by choosing a longer filter and the filter could also be chosen optimally for each frame though that of course would cause speed loss at the decoder and encoder side ...

Michael Niedermayer	a68ca08e30	cleanup mc_block() perform interpolation steps in such an order that halfpel interpolation could be done per picture this also makes mc_block() match h.264 for the 1/4 pel cases so that the use of the h264 functions for some cases does not introduce a fantastic mess Originally committed as revision 10433 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
