2013-02-23av_memcpy_backptr: avoid an infinite loop for back = 0Anton Khirnov
CC:libav-stable@libav.org
2013-02-20intreadwrite: tomi: Add missing attributes.h #include for av_always_inlineDiego Biurrun
2013-02-20x86: Use simple nop codes for <= sse (rather than <= mmx)Ronald S. Bultje
The "CentaurHauls family 6 model 9 stepping 8" family of CPUs (flags: fpu vme de pse tsc msr cx8 sep mtrr pge mov pat mmx fxsr sse up rng rng_en ace ace_en) SIGILLs on long nop codes. Signed-off-by: Martin Storsjö <martin@martin.st>
2013-02-14avutil: Ensure that emms_c is always defined, even on non-x86Diego Biurrun
2013-02-14avutil: Move emms code to x86-specific headerDiego Biurrun
2013-02-12lavu: avoid clashing definition of ELuca Barbato
E is usually defined as a shorthand for AV_OPT_FLAG_ENCODING_PARAM. Rename the single expansion E(x) now used in libavutil to E1.
2013-02-11crc: Move static data table from header to .c fileDiego Biurrun
Having static data tables in header files is a potential source of trouble.
2013-02-11arm: Fall back to runtime cpu feature detection via /proc/cpuinfoMartin Storsjö
On recent android versions, /proc/self/auxw is unreadable (unless the process is running running under the shell uid or in debuggable mode, which makes it hard to notice). See http://b.android.com/43055 and https://android-review.googlesource.com/51271 for more information about the issue. This makes sure e.g. neon optimizations are enabled at runtime in android apps even when built in release mode, if configured to use the runtime detection.

2013-02-09dsputil: Move LOCAL_ALIGNED macros to libavutilDiego Biurrun
2013-01-25dict: add av_dict_parse_string()Justin Ruggles
Can be used to set multiple key/value pairs from a string. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
2013-01-25lavu: Add av_strnstr()Vladimir Pantelic

Signed-off-by: Diego Biurrun <diego@biurrun.de>
2013-01-23float_dsp: Include config.h for redefining restrictMartin Storsjö
This makes sure that the restrict keyword is mapped to whatever keyword the compiler prefers/supports. This fixes building on MSVC (and possibly on GCC 2.x as well). Signed-off-by: Martin Storsjö <martin@martin.st>
2013-01-22floatdsp: move scalarproduct_float from dsputil to avfloatdsp.Ronald S. Bultje
This makes the aac decoder and all voice codecs independent of dsputil.
2013-01-22floatdsp: move butterflies_float from dsputil to avfloatdsp.Ronald S. Bultje
This makes wmadec/enc, twinvq and mpegaudiodec (i.e. mp2/mp3) independent of dsputil.
2013-01-22floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp.Ronald S. Bultje
Now, nellymoserenc and aacenc no longer depends on dsputil. Independent of this patch, wmaprodec also does not depend on dsputil, so I removed it from there also.
2013-01-22floatdsp: move vector_fmul_add from dsputil to avfloatdsp.Ronald S. Bultje
2013-01-19x86: Add a Yasm-based emms() replacementMartin Storsjö
This provides a fallback when building with Yasm enabled, but neither inline assembly, nor the _mm_empty intrinsic are available or enabled. Signed-off-by: Diego Biurrun <diego@biurrun.de>
2013-01-19x86inc: Add cvisible macro for C functions with public prefixDiego Biurrun
This allows defining externally visible library symbols. Signed-off-by: Diego Biurrun <diego@biurrun.de>
2013-01-18x86inc: Rename "program_name" to "private_prefix"Diego Biurrun
The new name is more descriptive and will allow defining a separate public prefix for externally visible library symbols. Signed-off-by: Diego Biurrun <diego@biurrun.de>
2013-01-17float_dsp: Add #ifdef HAVE_INLINE_ASM around vector_fmul_windowMartin Storsjö

2013-01-16lavc: Move vector_fmul_window to AVFloatDSPContextJustin Ruggles
Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

2013-01-15lavu: Add an API for calculating HMAC (RFC 2104)Martin Storsjö

2013-01-06x86: ABS1: port to cpuflagsDiego Biurrun
2012-12-31Drop unnecessary 'l' length modifier when printfing double values.Diego Biurrun
%f denotes a double argument and 'l' does nothing in this case according to the C spec.

2012-12-07arm: rename ARMVFP config symbol to VFPMans Rullgard
