2013-11-24Add missing #includes for *INT64_MAX and *INT64_CDiego Biurrun
2013-03-07Use the avstring.h locale-independent character type functionsReimar Döffinger
Make sure the behavior does not change with the locale. Signed-off-by: Martin Storsjö <martin@martin.st>
2012-11-14avutil: change GET_UTF8 to not use av_log2()Mans Rullgard
This removes an inter-library dependency on ff_log2_tab causing linking errors in some configurations. Signed-off-by: Mans Rullgard <mans@mansr.com>
2012-10-20avutil: remove inline av_log2 from public APIMans Rullgard
This removes inline av_log2 and av_log2_16bit from the public API, instead exporting them as regular functions. In-tree code still gets the inline and otherwise optimised variants. Signed-off-by: Mans Rullgard <mans@mansr.com>
2012-10-12Move av_reverse table to libavcodecDiego Biurrun
It is only used in that library.
2012-08-13libavutil: add saturating addition functionsMans Rullgard
Fixed-point audio codecs often use saturating arithmetic, and special instructions for these operations are common. Signed-off-by: Mans Rullgard <mans@mansr.com>
2012-01-03Add av_popcount64Daniel Verkamp
Signed-off-by: Janne Grunau <janne-libav@jannau.net>
2011-11-25MK(BE)TAG: avoid undefined shiftsMans Rullgard
Casting the left-most byte to unsigned avoids an undefined result of the shift by 24 if bit 7 is set. This affects the rm demuxer. Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-06-24doxygen: Consistently use '@' instead of '\' for Doxygen markup.Diego Biurrun
Signed-off-by: Diego Biurrun <diego@biurrun.de>
2011-05-14Add av_clip_uintp2() functionMans Rullgard
Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-03-19Replace FFmpeg with Libav in licence headersMans Rullgard
Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-02-18Force inlining of avutil common routinesJason Garrett-Glaser
On some versions of gcc, these weren't always getting inlined due to hitting the inline cap limit in some files. This is generally bad, as most of these functions are smaller inlined than not.

2010-03-09Fix build on configurations without fast av_log2()Måns Rullgård
