Nicolas George	3e1d3ebf5e	parseutils: replace setenv() by putenv(). putenv() seems to be more portable.	13 years ago
Mans Rullgard	6eca84bad8	cpu: recognise only cpu flag names pertinent to the architecture Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	3527a73933	avutil: add av_parse_cpu_flags() function This moves the cpu flag parsing code from avconv to avutil so it can be accessed elsewhere. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Justin Ruggles	c8af852b97	Add libavresample This is a new library for audio sample format, channel layout, and sample rate conversion.	13 years ago
Reimar Döffinger	2b336df3cb	parseutils: reliably detect out-of-range alpha. This should fix the FATE test on ARM (not tested), but it should also detect alpha values like 2^128 reliably as invalid which would be another out-of-range case with implementation-dependant behaviour. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Justin Ruggles	83b26046fc	avutil: change default buffer size alignment for sample buffer functions Aligning nb_samples will give both correct plane pointer alignment and enough padding for SIMD-optimized functions.	13 years ago
Nicolas George	9b84f8a987	parseutils: add av_parse_time() test.	13 years ago
Nicolas George	43b7068070	parseutils: make av_parse_time() check for failure. Until now, av_parse_time() would accept "1:00" as "1" and silently ignore ":00". This patch also includes a few cosmetic changes.	13 years ago
Nicolas George	9246896f77	parseutils: add FATE test.	13 years ago
Mans Rullgard	d526c5338d	ARM: allow runtime masking of CPU features This allows masking CPU features with the -cpuflags avconv option which is useful for testing different optimisations without rebuilding. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Reimar Döffinger	9b1f776d75	Fix compilation with NASM. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Justin Ruggles	0c0d1bce7c	avutil: add audio fifo buffer The functions operate on the sample level rather than the byte level and work with all audio sample formats.	13 years ago
Nico Weber	a4a88fd42c	Remove .rodata alignment kludge for Mach-O if a recent enough yasm is used. Yasm was fixed in its r2161 and yasm 0.8.0 (Apr 2010) contained this fix. Nasm was fixed in 2.06 (Jun 2009): https://groups.google.com/group/alt.lang.asm/browse_thread/thread/fcc85bbc3745d893 I tested with yasm 0.7.99 and yasm 1.2.0.7, where this works fine. I also tested with nasm. The nasm shipping with Xcode is too old to understand ffmpeg's assembly, before and after the patch. Nasm 2.10 fails to compile fft_mmx.asm on trunk with libavcodec/x86/fft_mmx.asm:88: panic: section ".text" has already been specified with alignment 32, conflicts with new alignment of 16 but builds fine if I change the two alignment "16"s in x86inc.asm to "32". With this patch, nasm 2.10 fails with libavcodec/x86/fft_mmx.asm:39: panic: section ".rodata" has already been specified with alignment 32, conflicts with new alignment of 16 instead, but again builds fine with s/16/32/.

Loren Merritt	705f3d4759	x86inc: support AVX abstraction for 2-operand instructions Add cvtdq2ps and cvtps2dq to the AVX instruction list. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Michael Niedermayer	abe6330317	AVoption doxy: clarify a few needs in relation to AVClass less structs. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	b0e7321cf0	parseutils: include errors in test output.	13 years ago
Reimar Döffinger	1a65d50ee7	mem.c: fix wrong comment. Overwriting the av_malloc etc. functions is not easily possible anymore, even for systems that support overriding symbols in shared libraries in principle. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Justin Ruggles	5e8280d177	avutil: add better documentation for AVSampleFormat	13 years ago
Nicolas George	a9e7e98021	error: ensure error codes are signed negative ints. Based on a patch by Robert Nagy <ronag89@gmail.com>. It makes a difference when the error code is immediately cast into a larger integer, such as an int64_t.	13 years ago
Michael Niedermayer	62e5ef95ca	av_image_alloc: Align the width to 8 when align >= 8. This allows simd optimized routines to work in steps of 8 pixels without going over the linesize. (this matters for yuv->rgb24 for example) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Diego Biurrun	baaab6069a	build: Move all arch OBJS declarations into arch subdirectory Makefiles.	13 years ago
Henrik Gramner	729f90e268	x86inc improvements for 64-bit Add support for all x86-64 registers Prefer caller-saved register over callee-saved on WIN64 Support up to 15 function arguments Also (by Ronald S. Bultje) Fix up our asm to work with new x86inc.asm. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Martin Storsjö	14f063d294	mem: Consistently return NULL for av_malloc(0) Plain POSIX malloc(0) is allowed to return either NULL or a non-NULL pointer. The calling code should be ready to handle a NULL return as a correct return (instead of a failure) if the size to allocate was 0 - this makes sure the condition is handled in a consistent way across platforms. This also avoids calling posix_memalign(&ptr, 32, 0) on OS X, which returns an invalid pointer (a non-NULL pointer that causes crashes when passed to av_free). Abort in debug mode, to help track down issues related to incorrect handling of this case. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Reimar Döffinger	24eac3cff5	Mark GRAY8 format as pseudo-paletted. This fixes that the GIF encoder crashes with it because it has no palette. And the arguments for the pseudopalette apply to gray8 as much as to RGB8 etc. In addition the changes required in lavfi should be needed anyway when adding support for RGB8 etc. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago

Diego Biurrun	e7e19b15c7	build: Only clean the architecture subdirectory we build for. This allows simplifying the Makefiles; it is no longer necessary to register arch subdirectory Makefiles, just putting them in place is enough.	13 years ago
