Ari Koivula 0df974cb0d Change sad functions to accept negative block widths. 
This makes boundary checking clearer.
 2013-10-11 14:11:21 +03:00
Ari Koivula 235b1ec0bc Add rest of the quadrants for sad calculation. 
- All tests pass.
- Movement vectors that don't overlap with the frame aren't handled yet.

Ari Koivula 356a0e8a14 Change SAD-test offset. 
Using 3 instead of 4 avoids having symmetric negation of the offset, like
-4 and +4. It also makes the expected result easier to calculate by hand.

Marko Viitanen 13bbd2fb37 Fixed inter_get_mv_cand() candidate selection of B0 CU 2013-10-02 15:10:40 +03:00
Ari Koivula 36fe88caef Fix rounding errors in chrome half pel prediction. 
The spec speaks nothing about rounding these values, but HM12 rounds the final
values. HM might be based on an old version of the spec that does all this rounding and clipping.

- Also fixes erroneous indexing when both horizontal and vertical are half pel.

Ari Koivula c753f6bac6 Fix boundary checking in CU visualization. 2013-10-02 11:11:21 +03:00
Ari Koivula 665b369164 Fix chroma problem in inter prediction. 
There is still a separate problem, but this fixes the visible chroma problem
with motion vectors that have reference a chroma half-pixel.

Ari Koivula 61eb3b3b71 Improve cu-visualization by arranging them to picture dimensions and colors. 2013-10-01 20:46:10 +03:00
Marko Viitanen 192b077dba Modified residual coding to allow inter block data (BUGGY!) 2013-10-01 10:54:10 +03:00
Ari Koivula 681975ad4b Fix inter reconstruction for 8x8 blocks and enable 8x8 inter blocks again. 
Inter reconstruction was modifying the movement in place when it shouldn't
have. This was causing issues only for the 8x8 blocks, because for larger
blocks the modified movement vector was too far away to be seen by the blocks
below it.

Ari Koivula 9bd35fcdb1 Remove split attribute from cu_info. 
It is no longer used.
