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).

Diego Biurrun	c18365402b	Replace Subversion revisions in comments by Git hashes.	13 years ago
Reimar Döffinger	d086c1203c	Add coverage exclusions for test code. For some of the code e.g. doing timing measurements there is no real point in running regression testing on it, thus it should not be counted against coverage. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Alex Converse	c9e5ac3380	aes: Avoid illegal read and don't generate more key than we use.	13 years ago
Mans Rullgard	d04d9f24a0	aes: allow unaligned input and output buffers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	8f175810be	aes: fix for big endian systems This was missed in `5d20f19` since CONFIG_SMALL was always broken for big endian. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	5d20f19be2	aes: fix invalid array indexing in init code This makes the code work with clang/x86_32 and removes several warnings. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	af2ea72495	aes: use direct assignments instead of memcpy() or loops Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	4bfe064460	aes: whitespace cosmetics Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Måns Rullgård	c184bb44db	aes: fix array index out of bounds warning Originally committed as revision 24048 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	19c039ee3d	Make mix function more readable. Compiler output unchanged with gcc 4.4. Originally committed as revision 24006 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	dd025f25da	Change AES code to be strict-aliasing-safe. Makes it give correct results with e.g. gcc 4.4. For unknown reasons the generate asm code also changes on e.g. gcc 4.3, making the code a bit larger but also a bit faster. Originally committed as revision 23896 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	2ad4a3bc78	Pass subshift an argument of the proper type. No changes in generated code. Originally committed as revision 23856 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Diego Biurrun	b56e34c5e9	Make AES test program compile again: Setting the av_log_level variable needs to be replaced by a call to av_log_set_level(). Originally committed as revision 18055 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
