Michael Niedermayer	85108195c5	avutil/common: minor simplification in av_clip_intp2_c() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	6d66e1a113	avutil/common: Fix integer overflow in av_clip_int8/16_c Fixes: signal_sigsegv_30420a5_2388_cov_1489993561_integra_lavf.mp4 Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
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

Stefano Sabatini	719b4eef5d	lavu/common: add warning to GET_UTF8 doxy Should prevent wrong uses, or at least decrease their chance.	11 years ago
Alfred E. Heggestad	16c3ed5837	libavutil: cast truncated values to uint32_t programs using ffmpeg that are compiled with -Wshorten-64-to-32 gives a warning when using header files common.h and rational.h cast 64-bit truncated values to (uint32_t) to avoid the warning Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Clément Bœsch	b3c263e209	lavu/common: make FF_CEIL_RSHIFT faster when shift is constant. See "[PATCH] lavfi/lut: use FF_CEIL_RSHIFT for chroma w/h rounding." thread for more information.	12 years ago
Clément Bœsch	570d63eef3	lavu: add FF_CEIL_RSHIFT and use it in various places.	12 years ago
Nicolas George	29ebb7ba8d	lavu: fix GET_UTF8 macro. Prevent 0xFE and 0xFF from being considered the start of non-standard 7-bytes sequences. No noticeable effect on speed.	12 years ago
Paul B Mahol	3e9c0217fd	lavu: add av_clipd_c Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 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
Reimar Döffinger	88d55b827d	Remove incorrect use of ctype.h functions. As far as I can tell the code should not change behaviour depending on locale in any of these places. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	12 years ago
Michael Niedermayer	f27eb1b702	lavu: check that assert level is defined fix warning Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	498e1c6bb9	lavu: check av_clip() limits This code cannot use av_assert due to circular header dependancies Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
Michael Niedermayer	ae52eb7fc7	lavu: add av_clip64() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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	545dc699f8	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. (cherry picked from commit `eb3755a5aa`)	14 years ago
