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!

Laurent Fasnacht 2456c65822 Replace accesses to picture->cu_array with picture_get_cu and picture_get_cu_const 2014-06-05 10:41:58 +02:00
Ari Koivula 1da94f2085 Stop deblocking from filtering edges not on 8x8 grid. 2014-05-19 15:58:54 +03:00
Ari Koivula 2224e18a46 Make deblocking work with transform splits.
- It used to work only with the implicit transform split from LCU size.
2014-05-19 15:58:54 +03:00
Laurent Fasnacht aac7fc55b1 Remove filter_deblock function, which is not used and somewhat dangerous, since it doesn't take into account specific stuff about subencoders. 2014-05-14 13:27:07 +02:00
Tapio Katajisto efc43c8b3a Added fractional pixel motion estimation
Added farctional mv support for inter recon

Laurent Fasnacht 6c6adf18c7 Refactor encoder_state 2014-05-07 11:47:31 +02:00
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.
2014-04-28 10:18:22 +03:00
Ari Koivula a539ae7e08 Address clang-analyzer warning.
- The assert needs to be before the initialization.
2014-04-22 11:55:28 +03:00
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.
2014-04-22 10:39:12 +02:00
Ari Koivula 54270f271d Fix c89 problem to allow compilation with VS2010. 2014-04-17 19:12:39 +03:00
Ari Koivula 32da12f653 Address a clang-analyzer warning about undefined behavior in filter.
- Analyzer didn't see that code is never called with MAX_DEPTH as it doesn't
  know the properties of width, height, x and y. Following would also
  silence the error:
    assert(cur_pic->width > 0 && cur_pic->height > 0);
    assert(cur_pic->width % 8 == 8 && cur_pic->height % 8 == 0);
    assert(x > 0 && y > 0);
    assert(x % 8 == 0 && y % 8 == 0);

- Related to issue #35.

Laurent Fasnacht 78c579053a encoder_control should be const in nearly all the code 2014-04-14 10:56:06 +02:00
Ari Koivula b19e4f3f2d Resolve possible uninitialized variable warnings.
- Working towards issue #11.

- Neither variable was actually used as uninitialized.

Ari Koivula 4d34377c42 Clean up deblocking code a bit.
- Change guards to use the same method of checking for coordinate alignment.

- Move variables to reduce their scope.

Ari Koivula 0f492c7680 Fix deblocking of transform boundaries.
This fixes issues with inter. Deblocking works now.
2014-03-21 10:42:41 +02:00
Ari Koivula c42b25054a Modify deblocking to be done per-LCU in the encoding loop.
- Intra works. There is still something wrong in inter.

- Avoid horizontal deblocking of the rightmost 4 pixels in the LCU.
  This is because vertical deblocking must be done for all pixels
  before horizontal, but vertical deblocking can't be done for those
  pixels before the next LCU is finished.

- Add separate deblocking of the rightmost pixels of the last LCU
  after the LCU edge has been deblocked.

- This is a pretty ugly hack but will have to do for now.

Ari Koivula 36fe88caef Fix rounding errors in chrome half pel prediction.
The spec speaks nothing about rounding these values, but HM12 rounds the final
values. HM might be based on an old version of the spec that does all this rounding and clipping.

- Also fixes erroneous indexing when both horizontal and vertical are half pel.
2013-10-02 14:49:23 +03:00
Ari Koivula 665b369164 Fix chroma problem in inter prediction.
There is still a separate problem, but this fixes the visible chroma problem
with motion vectors that have reference a chroma half-pixel.
2013-10-02 10:59:34 +03:00
Ari Koivula 04f1dde8a1 Fix overwriting of motion vectors during search.
- Makes everything besides search to only use the bottom most layer of the
  picture.cu_array structure.
