Mans Rullgard	97cb9236cf	ac3: move ac3_downmix() from dsputil to ac3dsp Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Derek Buitenhuis	e62e455f7b	dsputil/me/pixels: Actually use av_restrict Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Nedeljko Babic	b3fdfc8c4e	Optimization of AC3 floating point decoder for MIPS FFT in MIPS implementation is working iteratively instead of "recursively" calling functions for smaller FFT sizes. Some of DSP and format convert utils functions are also optimized.

Mans Rullgard	15616eb042	intrax8: move functions from dsputil to own context Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	dbc9f84ea6	Revert "dsputil: make {add/put/put_signed}_pixels_clamped() non-static." This reverts commit `484a337cd7`. These functions were used in `f8bed30` "VC1: merge idct8x8, coeff adjustments and put_pixels" which was reverted in `18b6a69`. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago

Mans Rullgard	f3eb008343	eamad/eatgq/eatqi: call special EA IDCT directly These decoders use a special non-MPEG2 IDCT. Call it directly instead of going through dsputil. There is never any reason to use a regular IDCT with these decoders or to use the EA IDCT with other codecs. This also fixes the bizarre situation of eamad and eatqi decoding incorrectly if eatgq is disabled. 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	cb5042d02c	float_dsp: Move vector_fmac_scalar() from libavcodec to libavutil	13 years ago
Ronald S. Bultje	17fad33f81	Change all uses of restrict to use av_restrict instead. Defining restrict results - for some compilers - in changing other uses of the restrict keyword also, e.g. __declspec(restrict) gets changed to __declspec(__restrict) on MSVC. This causes compilation failures. Therefore, using a private namespace macro instead is more reliable and robust. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Mans Rullgard	0a07f2b346	dsputil: fix invalid array indexing Indexing outside an array is invalid and causes errors with gcc 4.8. 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

Christophe GISQUET	7e1ce6a6ac	dsputil: remove shift parameter from scalarproduct_int16 There is only one caller, which does not need the shifting. Other use cases are situations where different roundings would be needed. The x86 and neon versions are modified accordingly. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	c23acbaed4	Don't use ff_cropTbl[] for IDCT. Results of IDCT can by far outreach the range of ff_cropTbl[], leading to overreads and potentially crashes. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Kostya Shishkov	2968bedf12	bink: make IDCT take 32-bit input Since IDCT transforming 32-bit input to 8-bit output is unusual and unpractical for most codecs, move Bink IDCT into separate context. Get rid of an additional permutation table while at it since SIMD support for Bink IDCT is unlikely to be implemented in foreseeable future. Quantisation tables also have to change type to signed for proper dequantisation of DCT coefficients. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Mans Rullgard	5cc2600964	dsputil: create 16/32-bit dctcoef versions of some functions High bitdepth H.264 needs 32-bit transform coefficients, whereas dnxhd does not. This creates a conflict with the templated functions operating on DCTELEM data. This patch adds a field allowing the caller to choose the element size in dsputil_init() and adds the required functions. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
