Ari Koivula 4751a3744b Fix intra mode search not doing boundary smoothing for DC.
- Move the boundary smoothing to the prediction function to make sure it's not
  forgotten.
2014-05-19 16:23:17 +03:00
Ari Koivula f9a603e4ea Move intra mode search form intra module to search module.
- Make the actual intra prediction function global.

- Move the rdo stuff to rdo module.

Ari Koivula 846b608125 Add transform split recursion to intra reconstruction. 2014-05-19 15:58:54 +03:00
Ari Koivula f0e990905e Remove chroma mode "36".
- It's an unnecessary chore to handle this special case everywhere (it means
  chroma_mode == intra_mode). Better just to use the actual mode.

Ari Koivula 9147b7acbf Split residual quantization to separate luma and chroma function. 2014-05-14 11:19:48 +03:00
Laurent Fasnacht 6c6adf18c7 Refactor encoder_state 2014-05-07 11:47:31 +02:00
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.

Laurent Fasnacht 19b1642aa2 Removed all cabac parameters (cabac is part of encoder_state) 2014-04-22 11:46:53 +02:00
Laurent Fasnacht 5fea5875a5 Huge refactoring
Split some parts of encoder_control into encoder_state
(idea: encoder_control is immutable)

Goal is to allow multiple substreams in the future.

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.

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.

Marko Viitanen b5fca8b206 Added missing chroma ref pixel init and fixed pic width/height in intra ref border

Luca Barbato 934a4e3b88 whitespace: Drop trailing spaces 2014-02-21 15:03:35 +01:00
Ari Koivula 8e63dd29bb Fix compiler warnings for VS2010 /W4 in intra.c.
- Working towards issue #11.
- Removed intra_get_block_mode as unused.
- Removed unused parameters from functions. Many of them were remnants from
  earlier data structures and earlier features of HEVC that have been removed.
- Lots of implicit conversions from larger types to smaller ones. I tried to
  avoid turning all of them to explicit ones this time and opted for changing
  the original data type instead. Had to do it in few cases though to stop the
  changes from propagating too widely.

Ari Koivula 09b742796f Simplify intra reference border construction.
Doesn't change anything but makes the control flow more clear.
2014-02-10 16:19:17 +02:00
Ari Koivula b440c48d07 Fix intra reconstruction on the bottom of the frame.
When the CU was both at the bottom of frame and at the bottom of LCU,
uninitialized pixels were being used as reference.

Ari Koivula 7bb9c25447 Remove duplicate implementation of intra_build_reference_border.
The search_buildReferenceBorder was an ugly hack and a place for bugs to hide
that should never have existed. Now it doesn't.

The change reduces PSNR a little, but also reduces the bitrate, when the
expected result was to have no change in either. I'm guessing there was still
some bug in the search_buildReferenceBorder, but the bug could also be in
intra_build_reference_border. Will have to do more testing to be sure, but
having one place to look at will be better than having two.
