Peter Meerwald	bf07d813f6	libavutil: Add av_clip_intp2 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>	10 years ago

Reimar Döffinger	efa7f42020	Use the avstring.h locale-independent character type functions Make sure the behavior does not change with the locale. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Mans Rullgard	7ba0c1b390	avutil: change GET_UTF8 to not use av_log2() This removes an inter-library dependency on ff_log2_tab causing linking errors in some configurations. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	8c0a3d5fe0	avutil: remove inline av_log2 from public API 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>	12 years ago
Diego Biurrun	d5c62122a7	Move av_reverse table to libavcodec It is only used in that library.	12 years ago
Mans Rullgard	6c4975eaaf	libavutil: add saturating addition functions Fixed-point audio codecs often use saturating arithmetic, and special instructions for these operations are common. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago

Mans Rullgard	6b34fbba9b	MK(BE)TAG: avoid undefined shifts 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>	13 years ago

Jason Garrett-Glaser	eb3755a5aa	Force inlining of avutil common routines 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.	14 years ago

Måns Rullgård	b90b1b4c3c	Fix build on configurations without fast av_log2() This is a bit hackish. I will try to think of something nicer, but this will do for now. Originally committed as revision 22366 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
