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
Reimar Döffinger	b223035511	Detect and check for CMOV. Some MMX-only CPUs do not have support for CMOV. All SSE/MMX2 CPUs should be fine, thus no check was added to those functions.

Stefano Sabatini	c28e7af70d	lavu: add timestamp.h header with convenience timestamp utilities	13 years ago
Diego Biurrun	f769cfedd8	build: Add missing directories to DIRS declarations.	13 years ago
Anton Khirnov	38d5533228	pixdesc: mark pseudopaletted formats with a special flag. This makes it possible to dintinguish them from PAL8. Fixes an invalid write in avpicture_layout().	13 years ago
Haruhiko Yamagata	166f399377	x86inc: support yasm -f win64 flag also. This sets __OUTPUT_FORMAT__ to win64 instead of win32, even though both (through -m amd64) produce 64-bit binary code. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Henrik Gramner	9cf7385309	x86inc: allow manual use of WIN64_SPILL_XMM. Functions using INIT_MMX may still access XMM registers through direct means (xmm0-15). Therefore, they still need to be marked for clobber so they can be properly saved/restored. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Alex Converse	314af0ff94	aacdec: Use correct speaker order for 7.1. The spec says the following speaker mapping is default: center front speaker left, right center front speakers, left, right outside front speakers, left surround, right surround rear speakers, front low frequency effects speaker	13 years ago
Stefano Sabatini	70ffda3217	lavu: introduce av_parse_ratio() and use it in ffmpeg and lavfi/aspect Factorize code and provide ratio parsing consistency.	13 years ago
Michael Niedermayer	d3f912c1f0	adler32: add comment for the SIMD code Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	26585d2a7f	adler32: rewrite using integer SIMD. about twice as fast as before. the not CONFIG_SMALL case is also droped as it is not faster than the CONFIG_SMALL case. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	7f8027b76f	adler32: avoid "too big" check in the inner loop Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Clément Bœsch	9477fa094b	lavu/timecode: use @see for URL in doxygen.	13 years ago
Ronald S. Bultje	7e4d9d5d45	win64: add a XMM clobber test configure option. This will be useful to test more aggressively for failures to mark XMM registers as clobbered in Win64 builds, and prevent regressions thereof. Based on a patch by Ramiro Polla <ramiro.polla@gmail.com>	13 years ago
Clément Bœsch	0eaa123b34	lavu: add public timecode API.	13 years ago
Paul B Mahol	8b933129b9	avutil: make intfloat api public The functions are already av_ prefixed and intfloat header is already provided. Install libavutil/intfloat.h Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago

Ronald S. Bultje	3b15a6d742	config.asm: change %ifdef directives to %if directives. This allows combining multiple conditionals in a single statement.	13 years ago
Alex Converse	08628b6afb	Revert "sws/pixfmt/pixdesc: add support for yuva444p" This reverts commit `fc115c80b7`. Tests are broken.	13 years ago

Reimar Döffinger	523f676b51	Use a full table for base64 decode. Also encodes error or end marker into table. About 20% faster. decode: 466491 -> 374139 decicycles syntax check: 236955 -> 161182 decicycles Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago

Michael Niedermayer	bdd739e91c	base64: Only run benchmark when "-t" is specified. As the test is run during fate and the benchmark is useless for fate this very slightly speeds up fate. Its also consistent with the other tests. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Stefano Sabatini	24860a913c	tools: add ffeval tool The tool is useful for testing the internal arithmetic evaluation engine (indeed I plan to use it in FATE), and provides a handy calculator when you can't rely on bc ;-).	13 years ago
Stefano Sabatini	999495734b	lavu/eval: add if() and ifnot() eval functions They allow to implement the if/then/else logic, which cannot be implemented otherwise. For example the expression: AB + not(A)C always evaluates to NaN if B is NaN, even in the case where A is 0.	13 years ago
