Ari Koivula 7e6c9aefe8 Add handling of more cases to sad calculation. 2013-10-10 21:51:27 +03:00
Ari Koivula d3561146d8 Change sad-tests to use chars instead of numbers to help with debugging. 
1 + 48 is ascii '1' and so on.
 2013-10-10 21:50:41 +03:00
Ari Koivula 4e36992752 Move basic SAD functions to picture-module. 2013-10-10 21:49:41 +03:00

Ari Koivula 1fcb452479 Simplify reference buffer calculation. 2013-10-10 21:48:55 +03:00
Ari Koivula 684f6d548c Start adding sad calculation outside frame. 
Works for top-left corner. 2/9 tests pass.
 2013-10-10 16:11:07 +03:00
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.
 2013-10-10 15:16:14 +03:00
Ari Koivula 2b4ca9b3e5 Remove tests as post build event from main project. 
It wasn't supposed to be there yet.

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.
 2013-10-02 14:49:23 +03:00
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.
 2013-10-02 10:59:34 +03:00
Ari Koivula 61eb3b3b71 Improve cu-visualization by arranging them to picture dimensions and colors. 2013-10-01 20:46:10 +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.
 2013-09-30 18:01:21 +03:00
Ari Koivula 9bd35fcdb1 Remove split attribute from cu_info. 
It is no longer used.

Ari Koivula f58e418a1a Fix out-of-bounds detection in mv-search. 
All blocks were intra because no movement vectors could be found.

Ari Koivula 8bce7c84a0 Disable early cutoff optimization for motion vector search.c 
It probably doesn't work right and might cause issues.
 2013-09-28 16:04:11 +03:00

Ari Koivula 2c894b49bf Disable cu-structure debug rendering.

 2013-09-25 18:18:10 +03:00
Ari Koivula 6f13168285 Add faster motion estimation algorithm. 
- New motion estimation does the same pattern as the old one, but centers the
  search on the best candidate at each step.
 2013-09-25 18:16:31 +03:00
Ari Koivula 04f1dde8a1 Fix overwriting of motion vectors during search.
