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

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

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
Reimar Döffinger	8650d5faf9	base64: more thorough decode tests. 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
Michael Niedermayer	57822f0660	base64: fix little typo 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

Daniel Verkamp	b73ec05473	Add av_popcount64 Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Reimar Döffinger	42a1f1d7a8	Avoid uninitialized data in lcldec when ofs is 0 in MSZH. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Reimar Döffinger	874da652b3	Avoid av_memcpy_backptr hang without extra branch. This only happens for a "back" value of 0 which is invalid anyway, but lcldec does not properly validate input. Also extend the documentation to specify valid values. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago

Carl Eugen Hoyos	c25c7ba87c	Make systematic palette opaque.	13 years ago
Michael Niedermayer	9eb0d8bab1	fifo: Make writes atomic. Prior to this a X bytes write could be seen as less than X bytes being available if the check was done at an unfortunate moment. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
