Jason Garrett-Glaser	f311208cf1	VP8: much faster DC transform handling 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.

Jason Garrett-Glaser	3ae079a3c8	VP8: optimize DC-only chroma case in the same way as luma. 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	15 years ago
Jason Garrett-Glaser	8a467b2d44	VP8: 30% faster idct_mb 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?

Ronald S. Bultje	3facfc99da	Change function prototypes for width=8 inner and mbedge loopfilter functions so that it does both U and V planes at the same time. This will have speed advantages when using SSE2 (or higher) optimizations, since we can do both the U and V rows together in a single xmm register. This also renames filter16 to filter16y and filter8 to filter8uv so that it's more obvious what each function is used for.

Jason Garrett-Glaser	0178d14fe5	First shot at VP8 optimizations: - MMXEXT, SSE2 and SSSE3 MC functions - MMX and SSE4 IDCT dc_add functions Patch by Jason Garrett-Glaser <darkshikari gmail com> and myself. Originally committed as revision 23815 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Jason Garrett-Glaser	d6f8476be4	Make VP8 DSP functions take two strides This isn't useful for the C functions, but will allow re-using H and V functions for HV functions without adding separate H and V wrappers.
