Stefano Sabatini	eab438eabb	lavu/samplefmt: fix/clarify documentation for av_samples_fill_arrays() In particular, avoid improper use of the term "channels" in place of "planes", and fix erroneous documentation for the linesize parameter.	13 years ago
Stefano Sabatini	3634441452	lavu/samplefmt: add note regarding buf validity in av_samples_fill_arrays() doxy	13 years ago
Diego Biurrun	e0c6cce447	x86: Replace checks for CPU extensions and flags by convenience macros This separates code relying on inline from that relying on external assembly and fixes instances where the coalesced check was incorrect.	13 years ago
Derek Buitenhuis	9ab538e31f	random_seed: Replace a VLA with a normal array Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Justin Ruggles	7327525997	x86: float_dsp: fix ff_vector_fmac_scalar_avx() on Win64 The SWAP macro does not work for explicit xmm/ymm usage, so instead just move the scalar value from xmm2 to xmm0.	13 years ago
Ronald S. Bultje	a4d71eb5c3	random_seed: Only read /dev/random if we have unistd.h unistd.h is used for open/read/close, but if this header does not exist, there's probably no use in trying to open /dev/random at all.

Michael Niedermayer	2bb62455c8	Revert "lavu: add snprintf(), vsnprint() and strtod() replacements for MS runtime." This reverts commit `ba53720280`. A better implementation has been commited by the same author to qatar Conflicts: configure Found-by: jamal <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Stefano Sabatini	29e972f67c	lavu/parseutils: add av_small_strptime() Make internal small_strptime() function public, and use it in place of strptime(). This allows to avoid a dependency on strptime() on systems which do not support it. In particular, fix trac ticket #992.	13 years ago
Stefano Sabatini	79dcd58d83	lavu/parseutils: make small_strptime() return a (non const) char * This is consistent with the standard definition of strptime().	13 years ago
Michael Niedermayer	42e63ec8dc	avopt: fix examples to match the same style about default values as the actual code. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

Stefano Sabatini	5666a1b270	lavu/opt: support NULL and special "none" values for size and pixel format options Allow to specify NULL values explicitly, thus overriding the default values set in the context.	13 years ago

Michael Niedermayer	d83ff76ca0	intreadwrite: Dont evaluate value for AV_W* multiple times. Evaluating it multiple times, can have side effects and is possibly slow. So its definitly a bad idea. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Loren Merritt	7a1944b907	vf_hqdn3d: x86 asm 13% faster on penryn, 16% on sandybridge, 15% on bulldozer Not simd; a compiler should have generated this, but gcc didn't.	13 years ago
Anton Khirnov	4d7adec8bd	AVOptions: store defaults for INT64 options in int64 union member. Double does not have enough precision to represent all int64 numbers exactly.	13 years ago

Mans Rullgard	5b170c0bea	x86: remove FASTDIV inline asm GCC 4.3 and later do the right thing with the plain C code. Earlier versions in 32-bit mode generate one extra instruction, needlessly zeroing what would be the high half of the shifted value. At least two gcc configurations miscompile the inline asm in some situations. In 64-bit mode, all gcc versions generate imul r64, r64 followed by shr. On Intel i7 and later, this imul is faster 32-bit mul. On older Intel and all AMD, it is slightly slower. On Atom it is much slower. Considering where the FASTDIV macro is used, any overall negative performance impact of this change should be negligible. If anyone cares, they should file a bug against gcc and get the instruction selection fixed. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Diego Biurrun	66baa45801	configure: Drop fastdiv option There is no point in having the user disable any fastdiv macros. Besides the condition implementation was broken and only disabled the C implementation, but no platform specific assembly versions.	13 years ago
Michael Niedermayer	4b529edff8	deprecate av_parse_cpu_flags This function is problematic in several ways, its also quite unpredictable which flags it ends up turning on Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Mans Rullgard	87fa05a0da	ARM: intmath: use native-size return types for clipping functions This avoids having the compiler redundantly mask the values to the smaller size. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	6c4975eaaf	libavutil: add saturating addition functions Fixed-point audio codecs often use saturating arithmetic, and special instructions for these operations are common. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Mans Rullgard	33de86db2b	dict: move struct AVDictionary definition to dict.c This makes struct AVDictionary fully opaque now that nothing needs to access it directly any more. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	987170cb9d	dict: add av_dict_count() This adds a function to retrieve the number of entries in a dictionary and updates the places directly accessing what should be an opaque struct to use this new function instead. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Mans Rullgard	1c4ab37c38	libavutil: drop offsetof() fallback definition The only compiler I have that does not define the standard offsetof() macro is "Bruce's C Compiler", a simple compiler for producing 8/16-bit 8086 code, usually for use in early stages of PC booting. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	d913fd1f00	libavutil: drop fallback definitions of INTxx_MIN/MAX This list is incomplete (we also use UINT16_MAX), so there does not appear to be any system we care about that needs these. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Mans Rullgard	d7a4f8f8b9	Move MASK_ABS macro to libavcodec/mathops.h This macro is only used in two places, both in libavcodec, so this is a more sensible place for it. Two small tweaks to the macro are made: - removing the trailing semicolon - dropping unnecessary 'volatile' from the x86 asm Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
