SanteriS 9e9f5e3150 Merge branch 'master' of https://github.com/ultravideo/kvazaar 2015-03-08 19:20:08 +02:00
SanteriS e2f9fe130a changed step 1 for tz_search 2015-03-08 19:19:23 +02:00
Ari Koivula 2f79bfebf7 Rename parameter encoder_state to state in all functions. 
- It's so widely used that there isn't really need to emphasize that
  it's the encoders state. Also, it isn't really the encoders state,
  but encoding jobs state.

SanteriS f478732b4c tz search bugfix 2015-02-25 15:28:45 +02:00
Ari Koivula d7383ccb25 Change license to LGPL. 
- Everyone who has contributed code to the project has been asked to license
  their contributions under LPGL and they have agreed.

- COPYING file changed to say LGPLv2.1 instead of GPLv2.

- GPL changed to LGPL in the header of every single file that a header and
  header added to the few that were missing one.

- Also.. Happy new year!
 2015-02-25 15:19:05 +02:00
Ari Koivula 3e58e03b56 Select motion compensation search starting point from among merge candidates. 
- Greatly reduces bdrate for most sequences.
 2015-02-25 12:58:15 +02:00
SanteriS 2f68cf3847 (TZ search) Fixed missing check for owf mode. Added 6 point hexagon search pattern. 2015-02-23 16:59:48 +02:00
Ari Koivula c979db7e95 Avoid sorting intra modes unnecessarily. 2015-02-19 16:25:45 +02:00
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.
 2015-02-19 16:25:28 +02:00
SanteriS 1a4d30d15a fixed step 1 of TZ algorithm 2015-02-11 18:51:21 +02:00
SanteriS ce4c251cd1 Merge branch 'master' of https://github.com/ultravideo/kvazaar 2015-02-09 17:29:49 +02:00
Ari Lemmetti 7846cf3093 Merge branch 'faster_interpolation' 2015-02-05 13:29:43 +02:00
SanteriS 50dd59eb21 Added different search patterns for TZ search. 2015-02-02 19:14:45 +02:00
SanteriS 4b3d77aaf2 Enable tz search. 2015-01-21 12:55:00 +02:00
Ari Koivula f86def8ed8 Remove unused variables. 2015-01-20 17:50:19 +02:00
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.
 2015-01-20 17:34:59 +02:00
Ari Koivula 870171e6ad Fix --rd=0 actually work. 2015-01-20 17:34:59 +02:00
Ari Lemmetti 0e56d13b5d Use smaller bit depth for fractional pixel interpolation 2015-01-15 15:00:09 +02:00
Ari Lemmetti cc061b4c3d Added ipol strategy for interpolation filters. 
Added initial files for AVX2 and generic strategies.
 2015-01-15 14:59:37 +02:00
Ari Koivula ab3364afb4 Add skipping of intra search in inter frames for rd=0. 2015-01-15 11:54:35 +02:00
Ari Lemmetti cad5f14372 Fixed compile errors (-Werror) 2015-01-14 18:27:35 +02:00
SanteriS 126569c737 Added first version of TZ search algorithm. 2015-01-14 14:54:09 +02:00
Ari Koivula 01195aecbb Move cu split model to a function. 2015-01-14 11:16:34 +02:00
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 edf2681ea4 Comment functions in search.c. 2015-01-07 14:56:14 +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.
