Diego Biurrun	e4a94d8b36	h264chroma: Change type of stride parameters to ptrdiff_t This avoids SIMD-optimized functions having to sign-extend their stride argument manually to be able to do pointer arithmetic.	8 years ago
Diego Biurrun	2143948381	Drop unnecessary av_unused attributes.	10 years ago
Diego Biurrun	7fb993d338	qpeldsp: Mark source pointer in qpel_mc_func function pointer const	10 years ago
Diego Biurrun	da5be23525	dsputil: Move RV40-specific bits into rv40dsp	11 years ago
Diego Biurrun	f9279ee749	dsputil: Move ff_zigzag_direct and ff_crop_tab declarations to mathops.h	11 years ago
Diego Biurrun	05563ccacc	dsputil: cosmetics: Lose camelCase on ff_cropTbl and ff_squareTbl names Also switch from "tbl" to "tab" name suffixes.	11 years ago
Janne Grunau	71617884a2	aarch64: h264 chroma motion compensation NEON optimizations Since RV40 and VC-1 use almost the same algorithm so optimizations for those two decoders are easy to do and included.	11 years ago
Diego Biurrun	67e6a9f558	cosmetics: Place arch initialization calls in alphabetical order	11 years ago
Martin Storsjö	9e0f14f16c	lavc: Make pointers to ff_cropTbl const There's no point in these pointers not being const. Signed-off-by: Martin Storsjö <martin@martin.st>	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	82bd04b170	rv34: Drop now unnecessary dsputil dependencies	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.

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
Janne Grunau	f101eab1be	x86: call most of the x86 dsp init functions under if (ARCH_X86) Rename the called dsp init functions to *_init_x86.	12 years ago
Martin Storsjö	1d9c2dc89a	Don't include common.h from avutil.h Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Christophe GISQUET	272b252c01	rv40dsp: implement prescaled versions for biweight. Quite often, the original weights are multiple of 512. By prescaling them by 1/512 when they are computed (once per frame), no intermediate shifting is needed, and no prescaling on each call either. The x86 code already used that trick.

Ronald S. Bultje	3ab9a2a557	rv34: change most "int stride" into "ptrdiff_t stride". This prevents having to sign-extend on 64-bit systems with 32-bit ints, such as x86-64. Also fixes crashes on systems where we don't do it and arguments are not in registers, such as Win64 for all weight functions.	13 years ago
Mans Rullgard	d8edf1b515	rv40: rearrange loop filter functions This splits the loop filter functions into smaller, more SIMD-friendly functions. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Janne Grunau	f5c05b9aa5	rv40: NEON optimised chroma MC Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Janne Grunau	bb8a6e03cc	rv40: move loop filter to rv34dsp context Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Janne Grunau	1bca8f4bc5	rv34: move inverse transform functions to DSP context	13 years ago
Kostya Shishkov	a80852316e	RV40: reuse some H.264 motion compensation functions in RV40. Since RV40 is based on H.264, it uses the same interpolation filters and functions for halfpel interpolation in one direction can be reused. Unfortunately other cases are implemented differently and produce slightly different output because of rounding. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Kostya Shishkov	b86ab38137	Add weighted motion compensation for RV40 B-frames Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago

Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Kostya Shishkov	2d8a081511	RV40 MC functions Originally committed as revision 15967 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
