* floatdsp: move scalarproduct_float from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
| | | | This makes the aac decoder and all voice codecs independent of dsputil.
* floatdsp: move butterflies_float from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
| | | | | This makes wmadec/enc, twinvq and mpegaudiodec (i.e. mp2/mp3) independent of dsputil.
* floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
| | | | | | 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.
* floatdsp: move vector_fmul_add from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22

* x86: Add a Yasm-based emms() replacementMartin Storsjö2013-01-18
| | | | | | | 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>
* x86inc: Add cvisible macro for C functions with public prefixDiego Biurrun2013-01-18
| | | | | | This allows defining externally visible library symbols. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* x86inc: Rename "program_name" to "private_prefix"Diego Biurrun2013-01-18
| | | | | | | 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>
* float_dsp: Add #ifdef HAVE_INLINE_ASM around vector_fmul_windowMartin Storsjö2013-01-17

| | | | | | | This supports HMAC-MD5 and HMAC-SHA1 for now, other hashes are simple to add. Signed-off-by: Martin Storsjö <martin@martin.st>

|
* Drop unnecessary 'l' length modifier when printfing double values.Diego Biurrun2012-12-31
| | | | | %f denotes a double argument and 'l' does nothing in this case according to the C spec.
* avstring: add av_basename and av_dirnameLuca Barbato2012-12-29
| | | | Thread safe version of the common basename and dirname.
* opt: avoid segfault in av_opt_next() if the class does not have an option listJustin Ruggles2012-12-22

* misc typo, style and wording fixesDiego Biurrun2012-12-18
|
* x86inc: fully concatenate tokens to fix macro expansion for nasmJanne Grunau2012-12-13
| | | | | Fixes build errors with nasm introduced in 6f40e9f070f7 for stack memory alignment. Noticed by BugMaster.
* x86inc: fix stack alignment on win64Ronald S. Bultje2012-12-12
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* x86inc: support stack mem allocation and re-alignment in PROLOGUERonald S. Bultje2012-12-12
| | | | | | | Use this in VP8/H264-8bit loopfilter functions so they can be used if there is no aligned stack (e.g. MSVC 32bit or ICC 10.x). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* x86: float_dsp: fix loading of the len parameter on x86-32Justin Ruggles2012-12-07
|
* arm: detect cpu features at runtime on LinuxMans Rullgard2012-12-07
| | | | | | | | This allows compiling optimised functions for features not enabled in the core build and selecting these at runtime if the system has the necessary support. Signed-off-by: Mans Rullgard <mans@mansr.com>
* arm: rename ARMVFP config symbol to VFPMans Rullgard2012-12-07
| | | | | | | This is consistent with usual ARM nomenclature as well as with the VFPV3 and NEON symbols which both lack the ARM prefix. Signed-off-by: Mans Rullgard <mans@mansr.com>
* arm: use HAVE*_INLINE/EXTERNAL macros for conditional compilationMans Rullgard2012-12-07
| | | | | | These macros reflect the actual capabilities required here. Signed-off-by: Mans Rullgard <mans@mansr.com>

* pixdesc: fix yuva 10bit bit depthPaul B Mahol2012-12-05
| | | | | | | It was wrongly set as the yuva 16bit one. Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* x86: af_volume: add SSE2/SSSE3/AVX-optimized s32 volume scalingJustin Ruggles2012-12-05
|
* lavu/opt: do not filter out the initial sign character except for flagsJustin Ruggles2012-12-05
| | | | This allows parsing of special-case negative numbers like decibels.
* eval: treat dB as decibels instead of decibytesJustin Ruggles2012-12-05
|
* float_dsp: add vector_dmul_scalar() to multiply a vector of doublesJustin Ruggles2012-12-05
| | | | Include x86-optimized versions for SSE2 and AVX.
* Remove pointless #undefs of previously forbidden functions.Anton Khirnov2012-12-04

* avutil: Use a configure check to enable windows console functionsMartin Storsjö2012-11-30
| | | | | | Not all versions or API subsets of windows have these functions. Signed-off-by: Martin Storsjö <martin@martin.st>
* avutil: Include io.h with a separate condition from windows console functionsMartin Storsjö2012-11-30
| | | | | | | | Not all versions of windows have the console color functions, while io.h might be needed for isatty (which can be found in unistd.h or io.h). Signed-off-by: Martin Storsjö <martin@martin.st>
* avutil: Include io.h with a separate condition from MapViewOfFileMartin Storsjö2012-11-29
| | | | | | | | | | | The existence of MapViewOfFile isn't linked to the existence of io.h. Not all versions of windows have MapViewOfFile (in particular, Windows Phone 8 and the "metro" windows 8 API subset don't), while they still have io.h (and need it for open/read/close). Signed-off-by: Martin Storsjö <martin@martin.st>
* x86: cpu: Drop unused HAVE_RWEFLAGS conditionDiego Biurrun2012-11-28
| | | | The test for rweflags was dropped in a previous commit.
* x86: float_dsp: add SSE version of vector_fmul_scalar()Justin Ruggles2012-11-26
|
* dsputil: move vector_fmul_scalar() to AVFloatDSPContext in libavutilJustin Ruggles2012-11-26

* base64: fix signed overflow in shiftMans Rullgard2012-11-26
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* remove #defines to prevent use of discouraged external functionsJanne Grunau2012-11-25
| | | | | | | | | | | Preventing the use of discouraged or 'insecure' external functions through defines in an internal header is not a good solution. The header is not guaranteed to be included universally which makes overlooking bad use of said functions during review more likely. There are cases were those functions either are the most straight forward solution or even have to be used. Using malloc or free is required if the allocation or release is done by other libraries.
* av_memcpy_backptr: optimise some special casesMans Rullgard2012-11-23
| | | | | | | | | - Add special cases for offsets of 2, 3, or 4 bytes. This means the offset is always >4 in the generic case, allowing 32-bit copies to be used there. - Don't use memcpy() for sizes less than 16 bytes. Signed-off-by: Mans Rullgard <mans@mansr.com>
* pixdesc: add PIX_FMT_ALPHA flagLuca Barbato2012-11-20

* x86: SPLATD: port to cpuflagsDiego Biurrun2012-11-18
