Anton Khirnov	cb45553f57	Remove pointless #undefs of previously forbidden functions.	12 years ago
Michael Niedermayer	ac090fa68c	lavu: keep context size variables They are essential to be able to use the utils without av_malloc() That is for example use with malloc(), memalign(), some other private allocation function, on the stack or others. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Martin Storsjö	9a92aea27b	avutil: Add functions for allocating opaque contexts for algorithms The current API where the plain size is exposed is not of much use - in most cases it is allocated dynamically anyway. If allocated e.g. on the stack via an uint8_t array, there's no guarantee that the struct's members are aligned properly (unless the array is overallocated and the opaque pointer within it manually aligned to some unspecified alignment). Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	4e4ae2f82c	sha: change loop condition to be tighter. This makes no change to the way the code functions, but should make it easier for static analyzers to see the valid range for i Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Diego Biurrun	6df5c528ca	Move some conditionally used variables into the block where they are used. This allows dropping the av_unused argument from them.	13 years ago
Kostya Shishkov	3e2aa268f6	sha: use AV_RB32() instead of assuming buffer can be cast to uint32_t* Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Anton Khirnov	488d2b6349	lavu: remove disabled sha1 cruft.	14 years ago

Måns Rullgård	8fc0162ac4	Add av_ prefix to bswap macros Originally committed as revision 24170 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	e6b22522c9	bswap: change ME to NE in macro names 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	15 years ago
Måns Rullgård	32f40ace25	sha: add missing include Originally committed as revision 22449 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	2ed6f39944	Replace many includes of libavutil/common.h with what is actually needed 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	15 years ago
Carl Eugen Hoyos	0fcbcad140	Include sha1.h from sha.c: It contains several prototypes. Originally committed as revision 22099 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	a768816c33	Simplify expression as suggested by Måns Rullgård Originally committed as revision 21756 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	045b60bf9b	Make SHA digest function write digest value with AV_WN32 instead of assuming that output may be written as uint32_t since output buffer may not be aligned (and it's silly to force alignment on it) and it does not work in that case properly on some architectures. Originally committed as revision 21754 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	8b4e7c28fb	Mark conditionally used variable T2 as av_unused; avoids the warning: libavutil/sha.c:183: warning: unused variable `T2' Originally committed as revision 19551 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Kostya Shishkov	451ae25724	Prepare SHA code to handle SHA-2 as well. For now rename files and functions and leave av_sha1_* functions for compatibility until next major bump. Originally committed as revision 19394 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Kostya Shishkov	0d73abb86a	Rename function to sha1_transform so it won't be confused with SHA-2 transform when it's added. Originally committed as revision 19389 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
