Adds struct merge_candidates_t for holding the spatial and temporal
merge candidates. Changes functions with separate parameters for each
candidate to use the struct instead.
Add tests for the extreme shapes that can happen when a motion vector
points outside the frame. A single pixel case where it probably doesn't
make sense to call a vectorized function, and the maximum size where it
definitely does make sense to call a vectorized function.
Inter SAD accesses pixels directly from the frame buffers, so give it
a 4k frame to work in for more realistic results. The old test used
intra test data, which consist of tiny buffers.
Sometimes the tests overrun their time limit by varying amounts.
Return calls per second based on the amount of time actually spent in
the loop instead of how much time we tried to spend in the loop.
The existing tests only covered the edge cases of border extension, but
not the SIMD optimized versions of reg_sad. This adds proper tests for
current optimized reg_sad implementations and ones we are likely to
have in the future.
Moves checks for motion vector prediction and merge candidate block
types (inter/intra) from functions kvz_inter_get_mv_cand and
kvz_inter_get_merge_cand to kvz_inter_get_spatial_merge_candidates.
The mac version of KVZ_GET_TIME macro has many statements, which
prevented it being used inside a for loop statement. Added brackets
to all versions to prevent this issue arising in the future.
Fixes#115.
- 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!
- Cast function pointers to correct function signatures.
- Increase number of buffers on SATD tests so the initialization doesn't
overflow them and initialize the unused buffers to null.
-Added vzeroupper to satd macro to prevent AVX-SSE transition penalties int picture_x86.asm
-Fixed the order of registers in zero extend macro in picture_x86.asm
-Fixed SATD checkers test pattern in satd_tests.c
