2014-01-26avutil: remove timer.h include from internal.hJanne Grunau
Added libavutil/timer.h include to all files with {START,STOP}_TIMER.
2012-10-12avutil: Add functions for allocating opaque contexts for algorithmsMartin Storsjö
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).

2011-07-03aes: fix for big endian systemsMans Rullgard
This was missed in 5d20f19 since CONFIG_SMALL was always broken for big endian. Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-07-03aes: fix invalid array indexing in init codeMans Rullgard
This makes the code work with clang/x86_32 and removes several warnings. Signed-off-by: Mans Rullgard <mans@mansr.com>

2010-07-02Make mix function more readable.Reimar Döffinger
Compiler output unchanged with gcc 4.4. Originally committed as revision 24006 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-06-30Change AES code to be strict-aliasing-safe.Reimar Döffinger
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

No changes in generated code. Originally committed as revision 23856 to svn://svn.ffmpeg.org/ffmpeg/trunk
