Diego Biurrun	383fd4d478	arm: Drop unnecessary ff_ name prefixes from static functions	12 years ago
Ronald S. Bultje	7384b7a713	arm: hpeldsp: Move half-pel assembly from dsputil to hpeldsp Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	015821229f	vp3: Use full transpose for all IDCTs This way, the special IDCT permutations are no longer needed. This is similar to how H264 does it, and removes the dsputil dependency imposed by the scantable code. Also remove the unused type == 0 cases from the plain C version of the idct.

Reimar Döffinger	8067f55edf	Fix compilation on ARM with android gcc 4.7 With the current code it fails due to running out of registers. So code the store offsets manually into the assembler instead. Passes "make fate-dts". Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	12 years ago
Ronald S. Bultje	62844c3fd6	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. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	de99545f46	Move arm half-pel assembly from dsputil to hpeldsp.	12 years ago
Ronald S. Bultje	d85c9b036e	vp3/x86: use full transpose for all IDCTs. This way, the special IDCT permutations are no longer needed. Bfin code is disabled until someone updates it. This is similar to how H264 does it, and removes the dsputil dependency imposed by the scantable code. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Luca Barbato	a8b6015823	dsputil: convert remaining functions to use ptrdiff_t strides Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Diego Biurrun	c242bbd8b6	Remove unnecessary dsputil.h #includes	12 years ago
Diego Biurrun	76b19a3984	Fix a number of incorrect intmath.h #includes.	12 years ago
Diego Biurrun	3e85b46ecf	arm: vp8: Add missing #includes for header to compile standalone	12 years ago

Carl Eugen Hoyos	cf36180143	Only set accelerated arm fft functions if fft is enabled. Fixes lavc compilation (linking) for configurations without fft. Reported-by: tyler wear Tested-by: Gavin Kinsey	12 years ago
Diego Biurrun	82bd04b170	rv34: Drop now unnecessary dsputil dependencies	12 years ago
Diego Biurrun	79dad2a932	dsputil: Separate h264chroma	12 years ago
Diego Biurrun	c9f933b5b6	Add av_cold attributes to arch-specific init functions	12 years ago
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	6c1a7d07eb	Use proper "" quotes for local header #includes	12 years ago
Martin Storsjö	2026eb1408	arm: vp8: Fix the plain-armv6 version of vp8_luma_dc_wht This makes the plain-armv6 version use the same registers as the armv6t2 version above. This fixes fate-vp8 on plain-armv6 devices. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Diego Biurrun	33552a5f7b	arm: Add mathops.h to ARCH_HEADERS list It is an arch-specific header not suitable for standalone compilation.	12 years ago
Janne Grunau	8e148b8742	arm: h264qpel: use neon h264 qpel functions only if supported	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.

Ronald S. Bultje	baf35bb4bc	dsputil: remove one array dimension from avg_no_rnd_pixels_tab.	12 years ago
Ronald S. Bultje	32ff643228	dsputil: remove avg_no_rnd_pixels8. This is never used.	12 years ago
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
Diego Biurrun	73b704ac60	arm: Add some missing header #includes	12 years ago
Ronald S. Bultje	5959bfaca3	floatdsp: move butterflies_float from dsputil to avfloatdsp. This makes wmadec/enc, twinvq and mpegaudiodec (i.e. mp2/mp3) independent of dsputil.	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	d56668bd80	floatdsp: move scalarproduct_float from dsputil to avfloatdsp. This makes the aac decoder and all voice codecs independent of dsputil.	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
Janne Grunau	68f18f0351	videodsp_armv5te: remove #if HAVE_ARMV5TE_EXTERNAL libavutil/arm/asm.S sets '.arch' depending on HAVE_ARMV5TE so that assembling armv5te code will always succeed even if the default -march flag does not support it. HAVE_ARMV5TE_EXTERNAL tests assembling code with the default arch. Fixes the missing symbol ff_prefetch_arm with --cpu= not including armv5te. CC: libav-stable@libav.org	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
Luca Barbato	6906b19346	lavc: add missing files for arm Across the many retouches those did not make the main commit.	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().

Diego Biurrun	523c7bd23c	misc typo, style and wording fixes	12 years ago
Michael Niedermayer	3193a5cdbf	arm: put prefetch under matching #ifdef as the actual code Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Mans Rullgard	b326755989	arm: rename ARMVFP config symbol to VFP 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>	12 years ago
Mans Rullgard	a7831d509f	arm: use HAVE*_INLINE/EXTERNAL macros for conditional compilation These macros reflect the actual capabilities required here. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	92dad6687f	arm: fix use of uninitialised value in ff_fft_fixed_init_arm() When initialising an FFTContext for a plain FFT, mdct_bits is not set and can contain a garbage value. Since nbits is always valid and for MDCT operation is mdct_bits - 2 checking this instead avoids using an uninitialised value while having the same effect. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Justin Ruggles	284ea790d8	dsputil: move vector_fmul_scalar() to AVFloatDSPContext in libavutil	12 years ago
Ronald S. Bultje	95c89da36e	Use ptrdiff_t instead of int for intra pred "stride" function parameter. This way, SIMD-optimized functions don't have to sign-extend their stride argument manually to be able to do pointer arithmetic.	12 years ago
Mans Rullgard	1846ddf0a7	ARM: fix overreads in neon h264 chroma mc The loops were reading ahead one line, which could end up outside the buffer for reference blocks at the edge of the picture. Removing this readahead has no measurable performance impact. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Diego Biurrun	9734b8ba56	Move avutil tables only used in libavcodec to libavcodec.	12 years ago
Jean-Baptiste Kempf	507dce2536	arm: call arm-specific rv34dsp init functions under if (ARCH_ARM) Assign NEON specific function pointers after runtime check via av_get_cpu_flags(). Signed-off-by: Janne Grunau <janne-libav@jannau.net>	12 years ago
