* x86inc: fix stack alignment on win64Ronald S. Bultje2012-12-121-4/+6
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* x86inc: support stack mem allocation and re-alignment in PROLOGUERonald S. Bultje2012-12-121-36/+149
| | | | | | | 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 Ruggles2012-12-071-1/+4
|
* arm: detect cpu features at runtime on LinuxMans Rullgard2012-12-071-0/+83
| | | | | | | | 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 Rullgard2012-12-074-5/+5
| | | | | | | 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 Rullgard2012-12-073-8/+8
| | | | | | These macros reflect the actual capabilities required here. Signed-off-by: Mans Rullgard <mans@mansr.com>
* x86: float_dsp: fix compilation of ff_vector_dmul_scalar_avx() on x86-32Justin Ruggles2012-12-061-1/+1
| | | | Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* pixdesc: fix yuva 10bit bit depthPaul B Mahol2012-12-051-20/+20
| | | | | | | 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 Ruggles2012-12-051-0/+1
|
* lavu/opt: do not filter out the initial sign character except for flagsJustin Ruggles2012-12-051-3/+8
| | | | This allows parsing of special-case negative numbers like decibels.
* eval: treat dB as decibels instead of decibytesJustin Ruggles2012-12-051-3/+24
|
* float_dsp: add vector_dmul_scalar() to multiply a vector of doublesJustin Ruggles2012-12-055-0/+89
| | | | Include x86-optimized versions for SSE2 and AVX.
* Remove pointless #undefs of previously forbidden functions.Anton Khirnov2012-12-0415-29/+0
|
* avutil: Use a configure check to enable windows console functionsMartin Storsjö2012-11-301-2/+2
| | | | | | 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 Storsjö2012-11-301-1/+3
| | | | | | | | 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 Storsjö2012-11-291-1/+3
| | | | | | | | | | | 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 Biurrun2012-11-281-1/+1
| | | | The test for rweflags was dropped in a previous commit.
* x86: float_dsp: add SSE version of vector_fmul_scalar()Justin Ruggles2012-11-262-0/+33
|
* dsputil: move vector_fmul_scalar() to AVFloatDSPContext in libavutilJustin Ruggles2012-11-264-0/+66
|
* base64: fix signed overflow in shiftMans Rullgard2012-11-261-2/+2
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* remove #defines to prevent use of discouraged external functionsJanne Grunau2012-11-251-34/+0
| | | | | | | | | | | 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 Rullgard2012-11-231-17/+103
| | | | | | | | | - 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 Barbato2012-11-202-24/+28

|
* crc: av_crc() parameter names should match between .c, .h and doxygenDiego Biurrun2012-11-161-1/+2
|
* avutil: change GET_UTF8 to not use av_log2()Mans Rullgard2012-11-141-4/+5
| | | | | | | This removes an inter-library dependency on ff_log2_tab causing linking errors in some configurations. Signed-off-by: Mans Rullgard <mans@mansr.com>
* x86: mmx2 ---> mmxext in asm constructsDiego Biurrun2012-11-141-1/+1
|
* pixdesc: add av_pix_fmt_get_chroma_sub_sampleLuca Barbato2012-11-132-0/+26
| | | | Deprecate avcodec_get_chroma_sub_sample.
* build: Drop AVX assembly ifdefsDiego Biurrun2012-11-111-4/+0
| | | | An assembler able to cope with AVX instructions is now required.
* lavu: rename audioconvert.* to channel_layout.* and deprecate audioconvert.hJustin Ruggles2012-11-115-184/+194
|
* x86inc: Set program_name outside of x86inc.asmDiego Biurrun2012-11-112-1/+2
| | | | This reduces the local difference to the x264 upstream version.
* x86: PALIGNR: port to cpuflagsDiego Biurrun2012-11-091-8/+8
|
* lavu: add av_ctz() for trailing zero bit countJustin Ruggles2012-11-054-2/+62

|
* x86: PMINUB: port to cpuflagsDiego Biurrun2012-11-021-5/+5
|
* x86util: Add cpuflags_mmxext alias for cpuflags_mmx2Diego Biurrun2012-11-021-0/+2
| | | | "mmxext" is a more sensible name and more common in outside projects.
* x86inc: Only define program_name if the macro is unsetDiego Biurrun2012-11-021-1/+3
| | | | This allows overriding the value from outside of the file.
* x86: Fix assembly with NASMDave Yeo2012-10-311-1/+1
| | | | | | | Unlike YASM, NASM only looks for include files in the current directory, not in the directory that included files reside in. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* x86: MMX2 ---> MMXEXT in macro namesDiego Biurrun2012-10-311-3/+3
|
* x86: include x86inc.asm in x86util.asmDiego Biurrun2012-10-313-2/+3
| | | | This is necessary to allow refactoring some x86util macros with cpuflags.

|
* avutil: Move memcpy_backptr() to mem.cDiego Biurrun2012-10-254-54/+50
| | | | The function is used elsewhere and does not belong with the LZO code.
* Remove need for padding in av_memcpy_backptr()Mans Rullgard2012-10-232-9/+9
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
