* lavu: add AV_CEIL_RSHIFT and use it in various placesClément Bœsch2016-01-11

* libavutil: move FFALIGN macro from common.h to macros.hJanne Grunau2015-12-14
| | | | | | | | | Include macros.h explicitly in common.h so that external code using FFALIGN does not break. It was already implicitly included through version.h. Include macros.h in lls.h and internal.h for FFALIGN. lls.h was including common.h only for FFALIGN and internal.h was missing the include for FFALIGN. `make checkheaders` did not catch it because it's an internal header.
* lavu: Drop deprecated av_reverse functionVittorio Giovara2015-08-28
| | | | Deprecated in 10/2012.
* libavutil: Add av_clip_intp2Peter Meerwald2015-02-21
| | | | | | | | | | | | | | | | | there already is a function, av_clip_uintp2() that clips a signed integer to an unsigned power-of-two range, i.e. 0,2^p-1 this patch adds a function av_clip_intp2() that clips a signed integer to a signed power-of-two range, i.e. -(2^p),(2^p-1) the new function can be used as a special case for av_clip(), e.g. av_clip(x, -8192, 8191) can be rewritten as av_clip_intp2(x, 13) there are ARM instructions, usat and ssat resp., which map nicely to these functions (see next patch) Signed-off-by: Peter Meerwald <pmeerw@pmeerw.net> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* Use the avstring.h locale-independent character type functionsReimar Döffinger2013-03-07
| | | | | | Make sure the behavior does not change with the locale. Signed-off-by: Martin Storsjö <martin@martin.st>
* avutil: change GET_UTF8 to not use av_log2()Mans Rullgard2012-11-14
| | | | | | | This removes an inter-library dependency on ff_log2_tab causing linking errors in some configurations. Signed-off-by: Mans Rullgard <mans@mansr.com>
* avutil: remove inline av_log2 from public APIMans Rullgard2012-10-20
| | | | | | | | 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>
* Move av_reverse table to libavcodecDiego Biurrun2012-10-12
| | | | It is only used in that library.
* libavutil: add saturating addition functionsMans Rullgard2012-08-13
| | | | | | | Fixed-point audio codecs often use saturating arithmetic, and special instructions for these operations are common. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Add av_popcount64Daniel Verkamp2012-01-03
| | | | Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* MK(BE)TAG: avoid undefined shiftsMans Rullgard2011-11-25
| | | | | | | | 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>
* doxygen: Consistently use '@' instead of '\' for Doxygen markup.Diego Biurrun2011-06-24

* Force inlining of avutil common routinesJason Garrett-Glaser2011-02-17
| | | | | | 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.

* 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
