* dsputil: Move LOCAL_ALIGNED macros to libavutilDiego Biurrun2013-02-08
|
* dsputil: Separate h264chromaDiego Biurrun2013-02-06
|
* Add av_cold attributes to arch-specific init functionsDiego Biurrun2013-02-05
|
* Use ptrdiff_t instead of int for {avg, put}_pixels line_size parameter.Diego Biurrun2013-02-05
| | | | | This avoids SIMD-optimized functions having to sign-extend their line size argument manually to be able to do pointer arithmetic.
* ppc: fmtconvert: Drop two unused variables.Diego Biurrun2013-02-01
|
* dsputil: Separate h264 qpelMans Rullgard2013-01-24
| | | | | | | | | | The sh4 optimizations are removed, because the code is 100% identical to the C code, so it is unlikely to provide any real practical benefit.

* Drop DCTELEM typedefDiego Biurrun2013-01-22
| | | | | | It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* 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
|
* vorbisdsp: change block_size type from int to intptr_t.Ronald S. Bultje2013-01-20
| | | | This saves one instruction in the x86-64 assembly.
* ppc: vorbisdsp: Drop some unnecessary #includesDiego Biurrun2013-01-20
| | | | Also fixes compilation with AltiVec disabled.
* ppc: Include string.h for memsetMartin Storsjö2013-01-20
| | | | | | | This fixes build failures on ppc machines with a compiler that supports -Werror=implicit-function-declaration. Signed-off-by: Martin Storsjö <martin@martin.st>
* Move vorbis_inverse_coupling from dsputil to vorbisdspcontext.Ronald S. Bultje2013-01-19
| | | | | Conveniently (together with Justin's earlier patches), this makes our vorbis decoder entirely independent of dsputil.
* vp3: integrate clear_blocks with idct of previous block.Ronald S. Bultje2013-01-19
| | | | | | | | | This is identical to what e.g. vp8 does, and prevents the function call overhead (plus dependency on dsputil for this particular function). Arm asm updated by Janne Grunau <janne-libav@jannau.net>. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* lavc: Move vector_fmul_window to AVFloatDSPContextJustin Ruggles2013-01-16
| | | | Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* lavc: introduce VideoDSPContextRonald S. Bultje2012-12-20
| | | | | | | | Move some functions from dsputil. The idea is that videodsp contains functions that are useful for a large and varied set of video decoders. Currently, it contains emulated_edge_mc() and prefetch(). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* ppc: replace pointer casting with AV_COPY32Mans Rullgard2012-11-12
| | | | | | This removes warnings about strict aliasing violations. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ppc: fix some unused variable warningsMans Rullgard2012-11-12
| | | | | | | The third argument of OP_U8_ALTIVEC is evaluated at most once so there is no need for a potentially unused temporary variable. Signed-off-by: Mans Rullgard <mans@mansr.com>
* build: non-x86: Only compile mpegvideo optimizations when necessaryDiego Biurrun2012-10-09
|
* ppc: fix Altivec build with old compilersMans Rullgard2012-10-08
| | | | | | | | | The vec_splat() intrinsic requires a constant argument for the element number, and the code relies on the compiler unrolling the loop to provide this. Manually unrolling the loop avoids this reliance and works with all compilers. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ppc: fmtconvert: kill VLA in float_to_int16_interleave_altivec()Mans Rullgard2012-10-05

* vp3: move idct and loop filter pointers to new vp3dsp contextMans Rullgard2012-07-18
| | | | | | | | This moves all VP3-specific function pointers from dsputil to a new vp3dsp context. There is no reason to ever use the VP3 IDCT where an MPEG2 IDCT is expected or vice versa. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ppc: Rename H.264 optimization template file for consistency.Diego Biurrun2012-06-12
|
* Add a float DSP framework to libavutilJustin Ruggles2012-06-08
| | | | Move vector_fmul() from DSPContext to AVFloatDSPContext.
* PPC: Move types_altivec.h and util_altivec.h from libavcodec to libavutilJustin Ruggles2012-06-08
| | | | | This will allow for easier implementation of Altivec functions in libraries other than libavcodec.
* ppc: Drop unused header regs.hDiego Biurrun2012-05-22
|
* ppc: add const where needed in scalarproduct_int16_altivec()Mans Rullgard2012-05-01
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* ppc: remove shift parameter from scalarproduct_int16_altivec()Mans Rullgard2012-05-01
| | | | | | | The shift parameter was removed from this interface in 7e1ce6a. This updates the Altivec implementation to match. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ppc: dsputil: do unaligned block accesses correctlyMans Rullgard2012-05-01
| | | | | | | | | | | | To load unaligned vector data in the usual way, explicit vec_ld() should be used rather than dereferencing a pointer to a vector type. When the VSX extension is enabled, gcc may compile vector pointer dereferences using the VSX lxvw4x instruction instead of the lvx instruction typically used with Altivec/VMX. As the behaviour of these instructions with unaligned addresses differs, it is important that only lvx is used here. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Remove lowres video decodingMans Rullgard2012-04-21
| | | | | | | This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ppc: drop unused function dct_quantize_altivec()Diego Biurrun2012-04-18
| | | | This also allows dropping some PPC-specific ugliness from dsputil.[ch].

* vp8: change int stride to ptrdiff_t stride.Ronald S. Bultje2012-03-02
| | | | | On 64bit platforms with 32bit int, this means we won't have to sign- extend the integer anymore.
