2014-04-17crc: add ANSI CRC16 LEAlessandro Ghedini
This adds the reversed byte-order version of the ANSI CRC16. Signed-off-by: Anton Khirnov <anton@khirnov.net>
2013-02-11crc: Move static data table from header to .c fileDiego Biurrun
Having static data tables in header files is a potential source of trouble.
2012-12-05Remove pointless #undefs of previously forbidden functions.Anton Khirnov
2012-11-02crc: move doxy to the headerAnton Khirnov
2011-12-04Code clean-up for crc.c, lfg.c, log.c, random_see.d, rational.c and tree.c.Yordan Makariev
Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2011-10-09crc: fix signed overflowMans Rullgard
This fixes a signed overflow from i << 24 when i == 255 by making i unsigned. The result of the shift is already assigned to an variable of unsigned type. Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-03-19Replace FFmpeg with Libav in licence headersMans Rullgard

2010-07-11Add av_ prefix to bswap macrosMåns Rullgård
Originally committed as revision 24170 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-07-11bswap: change ME to NE in macro namesMåns Rullgård
Other parts of FFmpeg use NE (native endian) rather than ME (machine). This makes it consistent. Originally committed as revision 24169 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-07-02Fix parameter name and position in av_crc_init Doxygen documentation.Diego Biurrun
Originally committed as revision 23981 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-06-30Fix grammar errors in documentationMåns Rullgård
Originally committed as revision 23904 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-09Replace many includes of libavutil/common.h with what is actually neededMåns Rullgård
This reduces the number of false dependencies on header files and speeds up compilation. Originally committed as revision 22407 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-06-12Fix cast of byte buffer to uint32 that was disregarding alignmentJeff Downs
requirements. Now calculates crc byte at a time until aligned, then continues with uint32 optimized calculation. This fixes crashes during mlp decoding on sparc (at least, maybe others). Originally committed as revision 19160 to svn://svn.ffmpeg.org/ffmpeg/trunk

Originally committed as revision 16840 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-01-14Change semantic of CONFIG_*, HAVE_* and ARCH_*.Aurelien Jacobs
They are now always defined to either 0 or 1. Originally committed as revision 16590 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-01-12Add necessary, remove unnecessary #includes.Diego Biurrun
Originally committed as revision 16547 to svn://svn.ffmpeg.org/ffmpeg/trunk

2008-02-01Dont cast const away.Michael Niedermayer
Originally committed as revision 11700 to svn://svn.ffmpeg.org/ffmpeg/trunk
2008-01-10Fix a couple of 'return type defaults to int' and 'control reaches end ofDiego Biurrun
non-void function' warnings in test code. Originally committed as revision 11491 to svn://svn.ffmpeg.org/ffmpeg/trunk
2008-01-07Fix access to the last element of the table.Aurelien Jacobs
(size of the table vs. number of elements in the table) Originally committed as revision 11448 to svn://svn.ffmpeg.org/ffmpeg/trunk
2008-01-05improve CRC APIAurelien Jacobs
- don't export any global var - provide either generated or hardcoded tables Originally committed as revision 11409 to svn://svn.ffmpeg.org/ffmpeg/trunk
2007-11-23main() --> main(void)Diego Biurrun
Originally committed as revision 11079 to svn://svn.ffmpeg.org/ffmpeg/trunk

Originally committed as revision 10151 to svn://svn.ffmpeg.org/ffmpeg/trunk
2007-08-19Use defines instead of raw hex numbers to specify CRC polynomialsReimar Döffinger
Originally committed as revision 10143 to svn://svn.ffmpeg.org/ffmpeg/trunk

Originally committed as revision 8397 to svn://svn.ffmpeg.org/ffmpeg/trunk

and fix GPL/LGPL version mismatches. Originally committed as revision 6577 to svn://svn.ffmpeg.org/ffmpeg/trunk
