* dsputil: Move LOCAL_ALIGNED macros to libavutilDiego Biurrun2013-02-08
|
* Drop DCTELEM typedefDiego Biurrun2013-01-22
| | | | | | It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* Don't use ff_cropTbl[] for IDCT.Ronald S. Bultje2012-03-06
| | | | | | | | Results of IDCT can by far outreach the range of ff_cropTbl[], leading to overreads and potentially crashes. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* prores-idct: fix overflow in c code.Ronald S. Bultje2011-10-14

* simple_idct: remove code for DCTELEM != int16Mans Rullgard2011-07-18
| | | | | | | DCTELEM can never be changed to anything else, too much code depends on it. Signed-off-by: Mans Rullgard <mans@mansr.com>

* 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
* Replace WORDS_BIGENDIAN with HAVE_BIGENDIANMåns Rullgård2009-07-26
| | | | Originally committed as revision 19508 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Use full internal pathname in doxygen @file directives.Diego Biurrun2009-02-01
| | | | | | | Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk

* consistency cosmetics: Rename POWERPC identifiers to PPC.Diego Biurrun2008-12-27
| | | | Originally committed as revision 16359 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Convert asm keyword into __asm__.Diego Pettenò2008-10-16
| | | | | | | | | | | | | Neither the asm() nor the __asm__() keyword is part of the C99 standard, but while GCC accepts the former in C89 syntax, it is not accepted in C99 unless GNU extensions are turned on (with -fasm). The latter form is accepted in any syntax as an extension (without requiring further command-line options). Sun Studio C99 compiler also does not accept asm() while accepting __asm__(), albeit reporting warnings that it's not valid C99 syntax.

* Move Alpha optimized IDCT to own file. Based on a patch by MånsFalk Hüffner2002-10-11
| | | | | | | | | Rullgård <mru@users.sourceforge.net>. I've left out the idctCol2 part, because W4 has recently been decreed to be 16383, and also I doubt it will give a noticeable speedup. Originally committed as revision 1029 to svn://svn.ffmpeg.org/ffmpeg/trunk
