* Restructure spatial direct MV generation so that the zero predictior shortcutMichael Niedermayer2010-02-13
| | | | | | | is closer at the top. 50-130 cpu cycles faster depending on which kind of direct MBs are meassured. Originally committed as revision 21788 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Split spatial and temporal direct MV generation.Michael Niedermayer2010-02-13
| | | | | | | | A little faster and needed for future optimizations. This sadly leads to some code duplication (which i hope i can factor out again after the optimizations on the direcr mv code are done) Originally committed as revision 21787 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Special case for spatial direct MV predictor being 0.Michael Niedermayer2010-02-13
| | | | | | a little less than 200 cpu cycles faster with the cathedral sample. Originally committed as revision 21785 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Pack MVs together from the begin for spatial direct, this simplifies the codeMichael Niedermayer2010-02-13
| | | | | | and is a bit faster (5-10 cpu cycles depending on what is meassured). Originally committed as revision 21784 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Reorder and factorize mb_type ifs, 1 cpu cycle faster and simpler.Michael Niedermayer2010-02-09
| | | | Originally committed as revision 21694 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Set partitioning to 16x16 for spatial direct MBs with mixed interlacing.Michael Niedermayer2010-02-08
| | | | | | | 11cylcles slower MV generation 98cycles faster MC Originally committed as revision 21691 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Detect spatial direct MBs partitioned smaller than 16x16 that can be partitionedMichael Niedermayer2010-02-08
| | | | | | | | as 16x16 (except ones changing interlacing relative to the colocated MB). 20 cycles slower during MV generation 175 cycles faster during MC Originally committed as revision 21690 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Detect equal 4x4 blocks in spatial direct MBs.Michael Niedermayer2010-02-08
| | | | | | | 19 cycles slower MV generation 575 cycles faster MC Originally committed as revision 21689 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Replace call to pred_motion() in direct spatial mv pred by codeMichael Niedermayer2010-02-08
| | | | | | | and simplify cases that cannot happen away. 8 cpu cycles faster Originally committed as revision 21683 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Merge mv&ref related code for spatial direct MV code.Michael Niedermayer2010-02-07
