Ari Koivula 6a384112cc Remove old unnecessary functions from search module. 
- As we move to per-LCU encoding only search_lcu will be necessary.

- Function search_best_mode is no longer used.
 2014-03-17 18:04:41 +02:00
Marko Viitanen c7ee176480 Removed unused function search_best_mode() 2014-03-17 12:56:04 +02:00
Ari Koivula 9563b50a34 Refactor coefficient group scan mapping lists. 
The relation between coefficients positions and coefficient group positions
was a big confusing due to the use of 16x16 diagonal coefficient mappings
also as coefficient group mappings.

- Moved all coefficient group mappings to their own const arrays and added
  a new array the select the correct coefficient group mapping. This removes
  special cases for 8x8 and 32x32 transform sizes.

- Removed all coefficient group mapping initialization from init_sig_last_scan.

- Removed 128x128 and 64x64 from regular coefficient group array as those
  transform sizes don't exist anymore in HEVC.

Marko Viitanen e6985eeb08 Terminate search when any block is found with no coefficients to code 2014-03-12 14:14:42 +02:00
Marko Viitanen 362fc6c5a5 Reduced bit cost when skip mode is selected 2014-03-12 14:13:38 +02:00
Ari Koivula aa59605392 Set correct max depth for search work-tree copying. 
The copy up and down functions had wrong max depth so they didn't work with
4x4 blocks.
 2014-03-12 14:02:13 +02:00
Marko Viitanen b5756821dd Tuned cost calculations for "final cost" 
By adding chroma cost and using 1.5x coeff cost instead of 0.5x, additional 3% (LP) and 1.8% (AI) drop in BD-rate noticed.
 2014-03-12 10:35:56 +02:00
Ari Koivula 409b094acf Try and get NxN to work again. 
- Moved NxN search to be done on the same level as other searches, as it's
  really not any different from 2Nx2N.
- Produces working bitstream but reconstruction is different.
 2014-03-11 19:19:20 +02:00
Marko Viitanen 75dd1f48ef Bugfix: calculate "final cost" only when block is inter or intra 2014-03-11 17:09:08 +02:00
Marko Viitanen 3b59d7c3a3 Implemented "final cost" calculation for best CU on each depth in search 
Take SAD between reconstruction and original and add cost from coding and cost for coding coefficients.

Ari Koivula 1b2705a042 Add video dimensions to the filename of encoder reconstruction. 2014-03-10 18:10:50 +02:00
Ari Koivula 965d8c377a Make encoder reconstruction obey --debug. 2014-03-10 18:10:49 +02:00
Ari Koivula 7e507fd615 Add --input-res CLI parameter. 
- Also set default width and height to 0 because it makes no sense to assume
  dimensions. It's kind of like defaulting to the most common altitude when
  the altimeter is broken.
- Add config_validate to have a place for checks on overall cfg state.
 2014-03-10 16:09:33 +02:00
Ari Koivula a644848b36 Add --seek CLI parameter. 
Related to issue #12.

Motivation for adding this is that the syntax for frame accurate seeking in
ffmpeg is a little cumbersome. Also it's kind of a standard feature I guess.

Ari Koivula 1cf03cfb37 Add --no-rdoq parameter. 2014-03-05 17:02:21 +02:00
Ari Koivula ca51f660d5 Fix fluctuation of coefficients on identical frames when RDOQ is on. 
Moves CABAC context initialization to take place before search. This fixes
an issue with RDOQ returning different coefficients for identical adjacent
frames.

- This actually probably worsens BD-rate a little for all frames except the
  first one because we were using last frames final CABAC context for every
  LCU and now we are using initialized CABAC contexts. The fix is to encode
  the LCU before we start compressing the next LCU so we can update CABAC
  contexts.
