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	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

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

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

Christophe GISQUET	7e1ce6a6ac	dsputil: remove shift parameter from scalarproduct_int16 There is only one caller, which does not need the shifting.

Diego Biurrun	0144fe6995	Remove Sun medialib glue code. It is obscure, most likely unused and not bit-exact compared to libavcodec due to a different IDCT transform algorithm.	13 years ago
Ronald S. Bultje	9b027c0d07	dsputil: set STRIDE_ALIGN to 16 for x86 also. This fixes crashes in e.g. PNG decoding with SSE2 enabled. In fact, many x86 optimizations for codecs assume that our buffer strides are 16-byte aligned.	13 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

Mans Rullgard	7b4ee3a21d	Remove h264_lowres_idct_put/add functions Use of these has been broken ever since the h264 idct was changed to always use transposed inputs. Furthermore, they were only ever used if some other non-default idct was requested. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	710b8df949	dsputil: remove ff_emulated_edge_mc macro used in one place This macro can cause problems in conjunction with the bitdepth template expansion. It was presumably added to keep source compatibility when high bitdepth support was added. However, emulated_edge_mc is a dsputil pointer and should not be called directly, so there is little reason to keep such a macro. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Oskar Arvidsson	19a0729b4c	Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 decoder. This patch lets e.g. dsputil_init chose dsp functions with respect to the bit depth to decode. The naming scheme of bit depth dependent functions is <base name>_<bit depth>[_<prefix>] (i.e. the old clear_blocks_c is now named clear_blocks_8_c). Note: Some of the functions for high bit depth is not dependent on the bit depth, but only on the pixel size. This leaves some room for optimizing binary size. Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
