2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun
Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-02-26Get rid of mb2b8_xy and b8_stride, change arrays organized based on b8_stride toMichael Niedermayer
ones based on mb_stride in h264. about 20 cpu cycles faster overall per MB Originally committed as revision 22065 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-02-18H264: use alias-safe macrosMåns Rullgård
This eliminates all aliasing violation warnings in h264 code. No measurable speed difference with gcc-4.4.3 on i7. Originally committed as revision 21881 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-02-1510l ;; gcc 2.95 compilation fix by mikeMichael Niedermayer
Originally committed as revision 21830 to svn://svn.ffmpeg.org/ffmpeg/trunk

Originally committed as revision 21789 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-02-13Restructure spatial direct MV generation so that the zero predictior shortcutMichael Niedermayer
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
2010-02-13Split spatial and temporal direct MV generation.Michael Niedermayer
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
2010-02-13Special case for spatial direct MV predictor being 0.Michael Niedermayer
a little less than 200 cpu cycles faster with the cathedral sample. Originally committed as revision 21785 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-02-13Pack MVs together from the begin for spatial direct, this simplifies the codeMichael Niedermayer
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
2010-02-09Reorder and factorize mb_type ifs, 1 cpu cycle faster and simpler.Michael Niedermayer
Originally committed as revision 21694 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-02-08Set partitioning to 16x16 for spatial direct MBs with mixed interlacing.Michael Niedermayer
11cylcles slower MV generation 98cycles faster MC Originally committed as revision 21691 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-02-08Detect spatial direct MBs partitioned smaller than 16x16 that can be partitionedMichael Niedermayer
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
2010-02-08Detect equal 4x4 blocks in spatial direct MBs.Michael Niedermayer
19 cycles slower MV generation 575 cycles faster MC Originally committed as revision 21689 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-02-08Branchless calculation of ref_offset.Michael Niedermayer
7 cpu cycles faster. Originally committed as revision 21685 to svn://svn.ffmpeg.org/ffmpeg/trunk

Originally committed as revision 21684 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-02-08Replace call to pred_motion() in direct spatial mv pred by codeMichael Niedermayer
