| * VP8: ARM NEON optimisations for dsp functionsMans Rullgard2011-02-07
| | | | | | | | | | | | | | This adds NEON optimised versions of all functions in VP8DSPContext. Based on initial work by Rob Clark. Signed-off-by: Mans Rullgard <mans@mansr.com>
| * VP8: don't overread edges on fourtap MC.Ronald S. Bultje2011-01-26
| | | | | | | | | | | | | | Fix C VP8 H+V MC functions which do two-dimensional 4/6-tap filters to not overread beyond their edges if the second filter is 4-tap, since the outer pixels aren't there anymore since 44002d8323023c35f51d523a7d305e45103ba7a1.

* VP8: much faster DC transform handlingJason Garrett-Glaser2010-08-02
| | | | | | | | | | A lot of the time the DC block is empty: don't do the WHT in this case. A lot of the rest of the time, there's only one coefficient: make a special DC-only transform for that case. When the block is empty, don't incorrectly mark luma DCT blocks as having DC coefficients. Originally committed as revision 24670 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP8: move zeroing of luma DC block into the WHTJason Garrett-Glaser2010-08-02
| | | | | | | Lets us do the zeroing in asm instead of C. Also makes it consistent with the way the regular iDCT code does it. Originally committed as revision 24668 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP8: optimize DC-only chroma case in the same way as luma.Jason Garrett-Glaser2010-07-23
| | | | | | | Add MMX idct_dc_add4uv function for this case. ~40% faster chroma idct. Originally committed as revision 24455 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP8: 30% faster idct_mbJason Garrett-Glaser2010-07-23
| | | | | | | | | | Take shortcuts based on statistically common situations. Add 4-at-a-time idct_dc function (mmx and sse2) since rows of 4 DC-only DCT blocks are common. TODO: tie this more directly into the MB mode, since the DC-level transform is only used for non-splitmv blocks? Originally committed as revision 24452 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP8: clear DCT blocks in iDCT instead of using clear_blocks.Jason Garrett-Glaser2010-07-23
| | | | | | ~0.3% faster overall. Originally committed as revision 24448 to svn://svn.ffmpeg.org/ffmpeg/trunk
