* motion_est: fix use of inline on extern functionsMans Rullgard2012-09-20
| | | | | | | | | | | | | | | | | | Inline functions declared without extern do not provide an external definition in standard C99. This code only works because most compilers do not implement the inline semantics correctly. With a stricter compiler, linking fails with unresolved references to these functions. Declaring the functions extern inline works correctly with some compilers while some others still fail to create external definitions. For maximum portability, create a static inline version with an externally visible wrapper for ff_get_mb_score. ff_epzs_motion_search is so large that no sane compiler inlines it anyway, so there the inline keyword can simply be dropped with no effect.

* motion_est: drop inline from sad_hpel_motion_search()Mans Rullgard2012-08-09
| | | | | | | This function is only ever called through a function pointer, so marking it inline makes no sense. Signed-off-by: Mans Rullgard <mans@mansr.com>

* motion_est: remove useless no_motion_search() functionMans Rullgard2012-08-09
| | | | | | | | At both places this function is called, mb_[xy] == s->mb_[xy] making the call together with following code equivalent to simply assigning zeros. Signed-off-by: Mans Rullgard <mans@mansr.com>

* Replace memset(0) by zero initializations.Diego Biurrun2012-03-28
| | | | Also remove one pointless zero initialization in rangecoder.c.

* motion_est: make MotionExtContext.map_generation unsignedMans Rullgard2011-10-11
| | | | | | | | The way this value is used, it should be an unsigned type. While the numerical value has no meaning, unsigned wraparound is relied upon. Signed-off-by: Mans Rullgard <mans@mansr.com>

* Eliminate FF_COMMON_FRAME macro.Diego Biurrun2011-07-11
| | | | | FF_COMMON_FRAME holds the contents of the AVFrame structure and is also copied to struct Picture. Replace by an embedded AVFrame structure in struct Picture.

* motion_est: fix implicit truncation warningsReimar Döffinger2010-07-07
| | | | | | Patch by Reimar Döffinger and Eli Friedman (independently). Originally committed as revision 24083 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-20
| | | | | | | | 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
* Optimize bidir_refine a bit.Michael Niedermayer2010-04-02
| | | | | | | 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
* Change bidir refine hash code so we only need to perform a singleMichael Niedermayer2010-04-02
| | | | | | | hash calculation for the whole function. negligibly faster (about 0.1%) Originally committed as revision 22775 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Reduce the size of the bidir refine hashtable from 4096 to 256 andMichael Niedermayer2010-04-02
| | | | | | | | 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. Originally committed as revision 22773 to svn://svn.ffmpeg.org/ffmpeg/trunk
