Ari Koivula d7383ccb25 Change license to LGPL. 
- Everyone who has contributed code to the project has been asked to license
  their contributions under LPGL and they have agreed.

- COPYING file changed to say LGPLv2.1 instead of GPLv2.

- GPL changed to LGPL in the header of every single file that a header and
  header added to the few that were missing one.

- Also.. Happy new year!

Ari Koivula d893a489d6 Fix mingw compilation issue. 
strategies/avx2/dct-avx2.c:334:25: error: pasting "g_dct_16" and "[" does
not give a valid preprocessing token

- The [ is not part of the token so compilation failed on mingw GCC 4.9.1.
- Fixes #86.

Ari Lemmetti fea517c2ae Misc code cleanup 2014-10-03 17:06:09 +03:00
Ari Lemmetti 85682c3b6a Removed unused transpose functions. 2014-10-03 11:39:31 +03:00
Ari Koivula f6272f06fc Unify signature for transform functions. 
- Some used block, coeff and some src, dst. Now all signatures are const input
  and non-const output.

Ari Lemmetti 0beb278f5b Partial butterfly strategy is now called DCT strategy. Made changes to transform functions in preparation for optimizations. 
-Moved fast_forward_dst and fast_inverse_dst to DCT strategies
 2014-07-31 13:25:28 +03:00
Ari Lemmetti 6bf63bd171 Added AVX2 strategy for partial butterfly (no optimizations yet) 2014-07-31 13:25:28 +03:00
Ari Koivula 669e99dd7f Improve intra SAD AVX2 intrinsics. 
- Moved implementations for different sizes to inline functions that are
  defined using each other, reducing the amount of redundant code.

- Performance of sad_8bit_32x32_avx2 improved by about 10% due to unrolling of
  the loop.
