Ari Koivula 1c2129fdcb Improve sort_modes. 
- When encoding with fast enough settings this function can use up to 5%
  of the cpu time, so I tried to optimize it a little bit.
 2015-02-19 16:25:38 +02:00
Ari Koivula 5fa6438b25 Clean up calls to memset. 
- Replaces all calls to memset with new FILL and FILL_ARRAY macros. The use
  of memset was inconsistent and we never use it for anything complicated.

Ari Koivula 81ad583e08 Use the same coeff cost calculation for all rd modes. 
- It's not worth it to have these faster approximations for coefficient cost.

Ari Koivula 8c89dcfc50 Move mode bit calculation to a function. 2015-01-14 10:44:52 +02:00
Ari Koivula fc79c2103e Generalize the fast intra-mode tryout code to work for any depth. 2015-01-12 11:47:21 +02:00
Ari Koivula f1364d297b Fix bug resulting in incorrect bitstream. 
- If 64x64 intra PUs were enabled and --rd was less than 2, no intra mode
  search was performed for depth 0 resulting in incorrect bitstream.
 2015-01-12 11:16:33 +02:00
Ari Koivula f4bd322804 Add command line options for prediction unit depth. 2015-01-12 10:40:34 +02:00

Ari Koivula 374012ab26 Merge branch 'intraskip' 2014-12-01 17:30:03 +02:00
Ari Koivula 21d221c075 Add fast 64x64 intra test. 
- If intra search is not enabled for a depth, try the result from the
  top left CU of the next depth. This seems to give most of the benefit
  of at least 64x64 intra prediction units without costing very much
  in performance.
 2014-11-20 17:20:24 +02:00
Ari Lemmetti 4874f2662f Added --subme commandline parameter for fractional pixel motion estimation: 1 == enable (default), 0 == disable. 2014-11-20 14:59:04 +02:00
Ari Lemmetti d5d2e04995 Merge branch 'fme' 2014-11-19 16:40:22 +02:00
Ari Koivula f6fead6221 Fix crash on inter frames. 
- If the bitcost was 0 it would underflow for skip mode. The bitcost is now
  checked before decrementing.
 2014-10-21 18:11:39 +03:00
Ari Koivula dfc67b766a Disable rd1 chroma search. 
- The bdrate improvement isn't really worth the time it takes, so enable it
  only for rd3 untill it can be made faster or better.
 2014-10-16 13:59:20 +03:00
Ari Koivula e9b8d9b889 Fix gcc warnings. 
- Remove unused variables.
- Change intra prediction functions to take their inputs as const pointers.
- Change intra_get_pred to take two pointers instead of an array of pointers,
  because the warnings got just too exotic.
 2014-10-16 13:17:46 +03:00
Ari Koivula 4bac52d9b6 Merge branch 'intra' 2014-10-16 13:11:23 +03:00
Ari Koivula 02ec26fcea Try different number of chroma intra modes for different depths. 
- And avoid doing extra work if no extra modes are tested for certain depths.
 2014-10-16 12:21:36 +03:00

Ari Koivula 3e6023dfb5 Rename search constants and set sane defaults. 2014-10-16 03:08:11 +03:00
Ari Koivula 8a407b0313 Estimate luma and chroma intra mode bits separately. 
- Remove cu_info.intra[].cost and bitcost as unnecessary.
- Add luma_mode_bits to complement chroma_mode_bits and remove
  intra_pred_ratecost as unneccessary. Difference is that intra_pred_ratecost
  was more coarse and included chroma mode with the assumption that it would
  be the same as chroma.
 2014-10-16 03:08:11 +03:00
Ari Koivula c9e212ba92 Add intra chroma mode search. 
- Based on full chroma reconstruction so enabled only for --rd=2.

Ari Koivula cbb2aa75b7 Add macros for adjusting weight of distortion between luma and chroma. 
- Everything needs to have a short name because windows has a maximum path
  length limitation that is breaking my testing framework.
 2014-10-08 10:31:54 +03:00
Ari Koivula 49ad845c33 Add cabac bits for part_mode. 2014-10-08 10:31:54 +03:00

- Remove unnecessary checks and comment.
 2014-10-08 10:31:54 +03:00
Ari Koivula e1b801eb6f Add transform tree chroma cbf bits. 2014-10-08 10:31:23 +03:00
Ari Koivula 3868cc7ff1 Fix crash on inter search when --tr-depth-intra is used. 
- Transform splits meant for intra modes were used for inter when inter mode
  was chosen, which caused an assert to be triggered if the split transform
  block didn't have any coefficients.
 2014-10-03 19:29:06 +03:00
Ari Koivula 8a80845b91 Add chroma to transform split search. 2014-10-03 11:36:57 +03:00
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.

- 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.

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)

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%.
 2014-04-08 12:43:26 +03:00
Ari Koivula 3c0977c7f3 Fix buffer overflow on copying of reference pixels.

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. 
- As we move to per-LCU encoding only search_lcu will be necessary.

- 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 ea312082a4 Simplify the prediction mode search recursion. 
No need to be so clever for something this simple.

I moved the cost initialization outside the recursing function because it
relied on the clever recursion to work. It should eventually be moved to its
own function that also initializes all the other fields just to be safe. I
didn't do that yet because I want to do it per-LCU and these functions are
still working on per-frame basis.

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.
