Marko Viitanen 3253ba4812 Fixed non-deterministic behavior when using bipred and owf 2015-06-08 13:14:53 +03:00
Ari Koivula c3b42291e1 Merge branches 'coverity-fix-5', 'coverity-fix-6', 'coverity-fix-7', 'coverity-fix-8', 'coverity-fix-9', 'coverity-fix-10', 'coverity-fix-11', 'coverity-fix-12', 'coverity-fix-13' and 'coverity-fix-14' into coverity-fixes2 2015-05-05 12:27:02 +03:00
Ari Koivula ed670f4185 Fix coverity warning.
- False positive about buffer overrun due to thinking work_tree_copy_up
  could be called with depth == 4.
2015-05-05 11:54:09 +03:00
Ari Koivula 80cbda364b Fix coverity warning.
- Variable guards dead code. Although, maybe it will complain about the
  dead code now instead.
2015-05-05 10:17:06 +03:00
Ari Koivula cc980fb815 Fix coverity warning.
- False positive for use of uninitialized variable.
2015-05-05 09:37:34 +03:00
Ari Koivula cf2a406aba Fix coverity warning.
- False positive for overflow. Fixed the parameter declaration.
2015-05-04 17:38:16 +03:00
Ari Koivula 1c3873f5b2 Fix coverity warning.
- Overflow from buggy implementation of modulo behavior for
  pattern_type. As there is no need for such behavior I removed it.
2015-05-04 17:38:16 +03:00
Ari Koivula 6234b09461 Fix coverity warning.
- A false alarm about buffer overflow. No new modes are added if all modes
  are already in the list.
- Skip checking predicted modes if all modes are in the list.

Marko Viitanen 50fce975d9 Clamp bi-pred motion vectors because ipol filtering requires modifications 2015-04-21 11:24:07 +03:00
Ari Koivula 7028846423 Fix bug in intra mode search.
- The cost of the first mode in the mode list was returned instead of cost of
  the selected mode, as this used to be the best mode when the list was
  sorted. Should only matter when doing inter coding.
- This pretty much affects only --rd=1 in inter frames.

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.

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.

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.

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 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 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 3cf5e422e8 Make fast chroma mode search select modes for slower chroma search. 2014-10-16 12:21:36 +03:00
Ari Koivula d12dbd4aa0 Add fast intra chroma mode search. 2014-10-16 12:21:08 +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.
