Ari Koivula 51662e1081 Fix differences between cu_rd_cost_luma and rdo_cost_intra. 2014-10-03 11:36:57 +03:00
Ari Koivula bc7d7d5cb6 Add cu_info* as parameter to reconstruction functions. 
- This is required so these functions can be used for searching. When NULL
  is given they take the CU from LCU struct as they did previously.

Ari Koivula 3c73892609 Fix transform split search. 
- Redo the search with the best mode to make sure the tr_depth parameters are
  correct.
 2014-09-11 10:56:53 +03:00
Ari Koivula 46b6b1243b Add --rd=3 mode and enable searching of intra depth 0. 
- intra_build_reference_border was overflowing at depth 0 because it uses
  arrays just large enough to accommodate 32x32 transforms, which is the
  biggest transform.
- For similar reasons search_intra_rough doesn't work at depth 0.
- The --rd=3 mode tries all modes with transform search. It also works without
  rough search so it was used to test depth 0 search. If --rd=3 is not on intra
  split at depth 0 is not searched for.

Ari Koivula 7ecf78bb70 Use sqrt lambda cost for searches not using SSD. 
- Add encoder_state->global->cur_lambda_cost_sqrt.

- Use sqrt lambda for inter search and rough intra search.

- The effect on inter is around 10-20% bdrate. The effect on intra is smaller
  and non-existent when --rd=2 is enabled, as the intra search refinement was
  already done with SSD and correct lambda.

Ari Koivula bd16a55b9b Always check DC and planar intra modes. 
- At least one of them is always in predicted modes, but to make sure they
  are both included add them explicitly.
 2014-06-17 12:51:15 +03:00
Ari Koivula 70740da123 Add smarter rough intra search. 
- Directional intra mode search is done using halving search from the best
  known mode. Starting modes are vertical, horizontal and the 3 diagonal
  modes.

- It's an unnecessary chore to handle this special case everywhere (it means

Laurent Fasnacht 0e6f1c99fc Refactor picture to remove hidden dependency between slice and tiles 
picture.type -> encoder_state->global->pictype
picture.slicetype -> encoder_state->global->slicetype
picture.slice_sao_luma_flag -> 1 (was constant)
picture.slice_sao_chroma_flag -> 1 (was constant)

This may be changed later. For now it's better to avoid having slice related stuff in picture.

Ari Koivula bdc16d2612 Improve cu_info coded block flag data structure a bit. 
- It works just like the old structure except that the flags are checked with
  bitmasks instead of having the flag value be propagated upwards. There isn't
  really any benefit to this because the flags still have to be propagated to
  parent CUs.

- Wrapped them inside a struct to make copying them easier. (Just need to copy
  the struct instead of making individual copies)
 2014-05-06 18:28:04 +03:00
Ari Koivula 4490e8afd6 Remove depth dimension from picture->cu_array. 
- It isn't used for anything anymore.

- It was used in the past to hold information during search, but now that
  information is held in lcu_t structs.

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.

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 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%.

Ari Koivula 3c0977c7f3 Fix buffer overflow on copying of reference pixels.

Marko Viitanen 0da8071300 Changed final cost (and transform skip) error function from SAD to SSD 2014-04-02 14:51:39 +03:00
Ari Koivula bbd1202f90 Replace old LCU reference pixels initialization with new ones. 
In the future we might even have just a const pointer to reference pixels.
 2014-03-19 16:01:31 +02:00
Ari Koivula 7328fc2897 Add special handling for bottom right LCU pixel. 
I didn't take into account that the reference pixel on the top-left of the
LCU gets over written if we just replace the top reference pixels for
current LCU with the bottom reference pixels after doing the search.
To handle this I copy the pixel that gets overwritten to the vertical
reference pixels.
 2014-03-19 16:01:31 +02:00
Ari Koivula 57ce7e990b Add new reference pixel buffer management to encoding loop. 
- This is necessary because after we add in-loop filters to be done per LCU,
  the reconstruction buffer will have the deblocked pixels. We only need the
  edge-pixels for intra prediction though so we just save those.

- Right now it only copies the pixels and passes them on to search, where
  the copied pixels are asserted to be the same ones we copy from
  reconstruction buffer.

- New yuv_t struct added for arrays of dynamic length. We might want to change
  other buffers to use it or something like it in the future.
 2014-03-19 16:01:30 +02:00
Ari Koivula 6a384112cc Remove old unnecessary functions from search module.
