* eamad/eatgq/eatqi: call special EA IDCT directlyMans Rullgard2012-07-29
| | | | | | | | | | | | 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>
* vp3: move idct and loop filter pointers to new vp3dsp contextMans Rullgard2012-07-18
| | | | | | | | 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>

* 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>

* 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: 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>

* 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>

* 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>
