Ari Koivula 880d09b27a Add sao_type_idx to SAO mode cost estimation. 2014-04-15 21:29:09 +03:00
Ari Koivula 280a946269 Apply bit cost fixes to edge band band sao search. 
- Increases bdrate slightly. It's still a cleaner solution though and further
  improvements to bit cost estimation might improve things.
 2014-04-15 21:28:16 +03:00
Ari Koivula c968253eb3 Estimate SAO merge coding costs better. 
- This doesn't seem to have very much of an effect. I guess the difference
  between 1 and 2 bits isn't that important.
 2014-04-15 21:27:16 +03:00
Ari Koivula ef7840c623 Add SAO coding costs for sao_eo_class, band position and offset sign. 
- This reduces bdrate a little bit.

- It seems like increasing the bit cost of using SAO in general
  increases bdrate.
 2014-04-15 21:24:44 +03:00
Ari Koivula 9ff32c566c Adjust SAO mode coding cost for zero offsets. 
- Coding zero with TR only takes one bit.

- Even though offset 0 should be fairly common, this doesn't seem to help very
  much and actually increases bdrate on some sequences.

Ari Koivula 67a3d5542c Add better delta distortion calculation to sao. 2014-04-15 21:17:29 +03:00
Ari Koivula 8c4796e56e Calculate edge and band sao separately. 2014-04-15 21:16:55 +03:00
Ari Koivula 1017c6639c Move band and edge sao to their own functions. 2014-04-15 21:14:59 +03:00

Laurent Fasnacht 52ae027b3a Avoid undefined behavior in memcpy calls 
"The memcpy() function shall copy n bytes from the object pointed to by s2 into the object pointed to by s1. If copying takes place between objects that overlap, the behavior is undefined."

Ari Koivula 29787efbbc Fix whitespace. 
Fix some whitespace issues from a merge.
 2014-04-11 17:06:21 +03:00
Ari Koivula 83d5a4753d Move input resolution to the same line as internal resolution. 
The \n must have been left there by accident.
 2014-04-11 16:55:08 +03:00

Ari Koivula 40c2fa4d46 Change intra reconstruction to use the same prediction function as search. 
- This fixes a bug with intra search. It sometimes used filtered reference
  pixels for 4x4 blocks leading to inaccurate cost estimate.
 2014-04-10 12:09:19 +03:00
Ari Koivula d5c3ad7a2b Move intra prediction generation to its own function. 2014-04-10 11:27:15 +03:00
Ari Koivula 088dd9ab96 Clean up intra mode search. 
- This changes the bitstream a little bit, because it changes the order in
  which the modes are tried and when two modes have the same cost the first
  one is chosen.

- Dst buffer was removes as it was no longer used.
 2014-04-10 10:25:57 +03:00
Marko Viitanen 43ae0a3b9a Implemented RDO cost calculation to Intra modes 2014-04-10 10:25:20 +03:00
Marko Viitanen c38ec1aa10 Added commandline option for RDO (--rd) 2014-04-09 12:29:15 +03:00
Marko Viitanen 6558c92020 Clean up get_coeff_cost() 
Since contexts were moved to cabac struct, there's no need to store contexts one by one
 2014-04-09 11:50:17 +03:00
Ari Koivula 92ac5025f9 Take intra mode based coeff scan mode into account for coeff bit cost. 
- Previously only diagonal scan mode, the most common one, would be used.

- This improved bdrate by 0.1-0.5 % for p0 and 0-0.2 % for p60.
 2014-04-09 10:44:44 +03:00
Ari Koivula c5dfcdf3aa Simplify scan mode selection. 
- The scan mode selection for chroma was a bit complicated so I checked it
  and it was all unnecessary. The mode selection is the same as for luma.
 2014-04-09 10:36:39 +03:00
Ari Koivula 3764688f84 Fix lambda initialization. 
- Lambda was initialized before slice type was set in encoder_control.
 2014-04-08 16:58:36 +03:00
Ari Koivula 0251bf5a1a Improve calculation of chroma coding cost for 4x4 blocks. 
- Adds calculation of chroma coefficient cost for 4x4 blocks.

- Previously there was no cost. Now the cost is added to the first prediction
  block for NxN.

- This fix should improve bdrate by about 1%.
