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	420719e141	Cosmetics: add do {} while 0 to macro. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Jean First	39bf7ffeb5	pixdesc: cosmetics Signed-off-by: Jean First <jeanfirst@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Reimar Döffinger	def19c9036	Unroll base64 decode loop. Around 50% faster. decode: 374139 -> 248852 decicycles syntax check: 236955 -> 123854 decicycles Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	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

Michael Niedermayer	112bca91b0	base64: optimize av_base64_encode() This makes the code 2-3 times as fast Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	a41687c2d6	base64: add benchmark Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Michael Niedermayer	2d9e2c6464	opt: Fix "libavutil/opt.c:811:20: warning: initialization discards ‘const’ qualifier from pointer target type [enabled by default]" 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
Clément Bœsch	5fc51c3155	lavu: add 2.1 channel layout.	13 years ago
Carl Eugen Hoyos	c3ff0713ef	Fix step_minus1 pixel descirption for RGB64.	13 years ago

Diego Biurrun	dff4af448d	timer: K&R formatting cosmetics	13 years ago
Janne Grunau	c04a954da6	lavu: bump lavu minor for av_popcount64 Add it to doc/APIchanges and update and correct other entries.	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
Michael Niedermayer	5a8e994287	mem: add av_max_alloc() to limit the maximum amount that may be allocated in one piece Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	58c41799ab	lzo: fix memcpy_backptr() with 0 offset Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
Michael Niedermayer	1674073b4d	libavutil: increase LIBAVUTIL_VERSION_MICRO to 100 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Diego Biurrun	c18365402b	Replace Subversion revisions in comments by Git hashes.	13 years ago
Luca Barbato	1ee5b5e823	lavu: add AVERROR_BUG error value It should be used to mark codepath that can be reached only through programming error.	13 years ago
Michael Niedermayer	75f2cc5134	avutil: check sampleformats enum, pict type enum and media type enum against insert/remove mistakes. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	68230eb375	pixfmts: Selfcheck against insertions / deletions in the enum. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Mans Rullgard	878dda5db1	build: move inclusion of subdir.mak to main subdir loop Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Diego Biurrun	58c42af722	doxygen: misc consistency, spelling and wording fixes	13 years ago
Anton Khirnov	1be323054e	Add basic libavdevice documentation.	13 years ago
Mans Rullgard	5b0d35eaed	x86: bswap: remove test for bswap instruction Firstly, this test never worked as intended, always reporting success. Secondly, bswap is available from 486 onward and can thus be assumed present. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	f64c2e710f	bswap: make generic implementation more compiler-friendly With these changes, gcc 4.5 and later recognise it as a bswap and use the proper instructions on ARM and x86. On x86, the 16-bit bswap is recognised from gcc 4.1. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	3383a53e7d	lavu: replace int/float punning functions The existing functions defined in intfloat_readwrite.[ch] are both slow and incorrect (infinities are not handled). This introduces a new header with fast, inline conversion functions using direct union punning assuming an IEEE-754 system, an assumption already made throughout the code. The one use of Intel/Motorola extended 80-bit format is replaced by simpler code sufficient under the present constraints (positive normal values). The old functions are marked deprecated and retained for compatibility. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Hanspeter Niederstrasser	bed04e2b03	Correct use of OSX to Mac OS X and properly format yasm providers on Mac OS X Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
