* Remove lowres video decodingMans Rullgard2012-04-21
| | | | | | | This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ppc: drop unused function dct_quantize_altivec()Diego Biurrun2012-04-18
| | | | This also allows dropping some PPC-specific ugliness from dsputil.[ch].
* dsputil: remove shift parameter from scalarproduct_int16Christophe GISQUET2012-03-07
| | | | | | | | | 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>
* libavcodec: Add ff_ prefix to j_rev_dct*Martin Storsjö2012-02-15

* libavcodec: Prefix fdct_ifast, fdct_ifast248Martin Storsjö2012-02-15
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* dsputil: Add ff_ prefix to the dsputil*_init* functionsMartin Storsjö2012-02-15
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* Remove Sun medialib glue code.Diego Biurrun2012-02-08
| | | | | It is obscure, most likely unused and not bit-exact compared to libavcodec due to a different IDCT transform algorithm.
* dsputil: set STRIDE_ALIGN to 16 for x86 also.Ronald S. Bultje2012-02-07
| | | | | | 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.

* dsputil: move a bink-only function to binkdspMans Rullgard2011-07-27

* dsputil: remove some unused functionsMans Rullgard2011-07-27

* dsputil: create 16/32-bit dctcoef versions of some functionsMans Rullgard2011-07-21
| | | | | | | | | | 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>
* jfdctint: add 10-bit versionMans Rullgard2011-07-21
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* Remove h264_lowres_idct_put/add functionsMans Rullgard2011-07-20
| | | | | | | | 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>
* dsputil: remove ff_emulated_edge_mc macro used in one placeMans Rullgard2011-07-10
| | | | | | | | | | 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>
* ac3enc: add int32_t array clipping function to DSPUtil, including x86 versions.Justin Ruggles2011-07-01

* 4:4:4 H.264 decoding supportJason Garrett-Glaser2011-06-13
| | | | Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.
* Roll back 4:4:4 H.264 for nowJason Garrett-Glaser2011-06-13
| | | | Needs some ARM/PPC asm modifications.

* Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 ↵Oskar Arvidsson2011-05-10
| | | | | | | | | | | | | | | | | 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>

* dsputil: add bswap16_buf()Mans Rullgard2011-03-16
| | | | | | | | There are several places where a buffer is byte-swapped in 16-bit units. This allows them to share code which can be optimised for various architectures. Signed-off-by: Mans Rullgard <mans@mansr.com>

* Make LOCAL_ALIGNED macro fully C99 compatibleMans Rullgard2011-01-22
| | | | | | | | | C99 variadic macros require more arguments than there are named parameters in the definition. This means we must use an extra indirection to avoid having two different macros for arrays with one resp more than one dimension. Signed-off-by: Mans Rullgard <mans@mansr.com>

* H.264/SVQ3: make chroma DC work the same way as luma DCJason Garrett-Glaser2011-01-15
| | | | | | | No speed improvement, but necessary for some future stuff. Also opens up the possibility of asm chroma dc idct/dequant. Originally committed as revision 26349 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Port SVQ3 to use the new mb_luma_dc method of storing luma DC coefficients.Jason Garrett-Glaser2011-01-15
| | | | | | | Doesn't help speed as there isn't an asm implementation yet, but consistency is a good thing. Originally committed as revision 26348 to svn://svn.ffmpeg.org/ffmpeg/trunk
