Ronald S. Bultje	1acd7d594c	h264: integrate clear_blocks calls with IDCT. The non-intra-pcm branch in hl_decode_mb (simple, 8bpp) goes from 700 to 672 cycles, and the complete loop of decode_mb_cabac and hl_decode_mb (in the decode_slice loop) goes from 1759 to 1733 cycles on the clip tested (cathedral), i.e. almost 30 cycles per mb faster.

Diego Biurrun	25841dfe80	Use ptrdiff_t instead of int for {avg, put}_pixels line_size parameter. This avoids SIMD-optimized functions having to sign-extend their line size argument manually to be able to do pointer arithmetic.	12 years ago
Diego Biurrun	4eef2ed707	ppc: fmtconvert: Drop two unused variables.	12 years ago
Mans Rullgard	e9d817351b	dsputil: Separate h264 qpel 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.

Diego Biurrun	88bd7fdc82	Drop DCTELEM typedef It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	12 years ago
Ronald S. Bultje	42d3246948	floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp. 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.	12 years ago
Ronald S. Bultje	55aa03b9f8	floatdsp: move vector_fmul_add from dsputil to avfloatdsp.	12 years ago
Ronald S. Bultje	1768e43ceb	vorbisdsp: change block_size type from int to intptr_t. This saves one instruction in the x86-64 assembly.	12 years ago
Diego Biurrun	d9bf716945	ppc: vorbisdsp: Drop some unnecessary #includes Also fixes compilation with AltiVec disabled.	12 years ago
Martin Storsjö	d160a2fb4c	ppc: Include string.h for memset This fixes build failures on ppc machines with a compiler that supports -Werror=implicit-function-declaration. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	fef906c77c	Move vorbis_inverse_coupling from dsputil to vorbisdspcontext. Conveniently (together with Justin's earlier patches), this makes our vorbis decoder entirely independent of dsputil.	12 years ago
Ronald S. Bultje	aeaf268e52	vp3: integrate clear_blocks with idct of previous block. 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>.

Justin Ruggles	e034cc6c60	lavc: Move vector_fmul_window to AVFloatDSPContext Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Michael Niedermayer	e16bac7b33	videodsp: Fix project name These are all part of splited out dsp utils from FFmpeg Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Ronald S. Bultje	8c53d39e7f	lavc: introduce VideoDSPContext 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().

Mans Rullgard	a384f6a7f7	ppc: replace pointer casting with AV_COPY32 This removes warnings about strict aliasing violations. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	031aac9861	ppc: fix some unused variable warnings 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>	12 years ago
Diego Biurrun	ac56ff9cc9	build: non-x86: Only compile mpegvideo optimizations when necessary	12 years ago
Mans Rullgard	f79364b2c3	ppc: fix Altivec build with old compilers 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>	12 years ago
Pavel Koshevoy	9425dc3dba	Fix build failure on osx 10.5.8 ppc Second parameter to vec_splat must be a literal, not a variable value. Therefore the second nested for-loop in float_to_int16_stride_altivec had to be unrolled. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Mans Rullgard	642b4efaf7	ppc: fmtconvert: kill VLA in float_to_int16_interleave_altivec() Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago

Mans Rullgard	28f9ab7029	vp3: move idct and loop filter pointers to new vp3dsp context 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>	13 years ago

Justin Ruggles	98db4e2a4e	PPC: Move types_altivec.h and util_altivec.h from libavcodec to libavutil This will allow for easier implementation of Altivec functions in libraries other than libavcodec.	13 years ago

Mans Rullgard	ce82dad7eb	ppc: remove shift parameter from scalarproduct_int16_altivec() 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>	13 years ago
Mans Rullgard	4c387c7070	ppc: dsputil: do unaligned block accesses correctly 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>	13 years ago
Michael Niedermayer	70d54392f5	lowres2 support. The new lowres support is limited to decoders where lowres decoding is possible in high quality. I was not able to measure any speed difference, but if one is found the 2-3 lines that might affect speed can be made compile time conditional Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Mans Rullgard	2bcbd98459	Remove lowres video decoding This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Ronald S. Bultje	bd66f073fe	vp8: change int stride to ptrdiff_t stride. On 64bit platforms with 32bit int, this means we won't have to sign- extend the integer anymore.	13 years ago
