Ari Koivula 80cd172f75 Clean up SAO encoding.
- Fixes a bug when pic->slice_sao_chroma == false.
2014-01-02 15:10:07 +02:00
Ari Koivula f1d8aae5b4 Clean up SAO encoding.
- Fixes a bug when pic->slice_sao_chroma == false.
2013-12-19 13:54:32 +02:00
Ari Koivula 8e2a7ef6ed Start implementing NxN prediction coding. 2013-12-18 14:55:05 +02:00
Ari Koivula 553bcdc324 Rewrite intra prediction mode coding to be simpler.
Should work exactly the same, but with the prediction mode selection done
separately from the binarization it's easier to see that the implementation
is correct.
2013-12-18 14:16:04 +02:00
Ari Koivula cf0d314d03 Clean up prediction mode coding.
This was done as preparation for adding NxN intra.

- Monochrome coding was removed as it's not part of the standard.
- No other functional changes.
2013-12-18 11:25:44 +02:00
Ari Koivula 8f610176d8 Add NxN part_mode coding. 2013-12-18 10:50:24 +02:00
Ari Koivula 3af65b8477 Add SAO searching and reconstruction for chroma.
One I frame and 99 P frames encoded with SAO off and on.
Processed 100 frames,    6693224 bits AVG PSNR: 30.7248 37.8978 37.8287

Ari Koivula a57b938270 Add new module sao.
- Move sao-stuff not directly related to encoding to sao-module.
- Calculate sao for all LCUs before encoding any of them. This is in
  preparation to doing the reconstruction line at a time instead of
  LCU at a time.
2013-11-04 19:41:01 +02:00
Ari Koivula 03f2967899 Block based sao dead end.
This will never work because the adjacent blocks require the original values
of the boundary pixels to make category decisions.
2013-11-04 17:55:29 +02:00
Ari Koivula 31af7e3929 Fix sao offsets. Reconstruction kind of works. 2013-11-04 13:05:05 +02:00
Ari Koivula 66fe302520 Fix cabac context for sao. HM accepts encoded sao. 2013-11-04 13:03:51 +02:00
Ari Koivula b6c5c87fb7 Merge branch 'master' into sao
SAO needs to be coded before LCU data has been searched. Searching
has already been moved to happen before encoding in the master branch.

Ari Koivula 116d5b14be Fix handling of non factor of 8 resolution.
- Reimplement bit filling routines to copy bits form the edge, instead of
  using a constant.

- Add real_width and real_height to encoder_input and store the actual input
  resolution in them instead of in encoder_input.width and height. This fixed
  a crash. It's also clearer.

- Correctly scale conf_win offsets to be in terms of chroma.
