Laurent Fasnacht bdc2d43180 Write bitstream directly after doing the search. This is required since we need the correct entropy status for wpp 2014-05-20 09:29:01 +02:00
Laurent Fasnacht 06532292fc Wavefront are in tile coordinates 2014-05-20 09:28:58 +02:00
Ari Koivula 551b087b47 Remove bunch of unnecessary code from encode_transform_unit.
- Really, it's useless. Selecting scan order isn't this hard.

- Checked from HM that ctx_idx doesn't have anything to do with contexts.

Ari Koivula a7cd31d87b Update the names of some bins to the current spec.
- Helps with debugging.
2014-05-16 05:44:03 +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.

Laurent Fasnacht 2c2a2528f3 Remove openmp stuff 2014-05-14 13:27:06 +02:00
Ari Koivula fb763f7940 Move coefficient generation functions from encoder.c to transform.c.
- These functions probably should have been there to begin with.
2014-05-12 11:37:39 +03:00
Ari Koivula a3478ecd20 Move transform skip decision to it's own function. 2014-05-12 11:18:27 +03:00
Ari Koivula d9b890de6e Remove redundant variables.
- Redefine LCU_WIDTH to be 64. Stuff will break horribly if it's
  anything else anyway.

- Add LCU_WIDTH_C for chroma LCU width. It should be more readable than the
  constant (LCU_WIDTH >> 1).
2014-05-12 10:58:07 +03:00
Ari Koivula 59e0e98523 Separate luma and chroma coefficient generation variables. 2014-05-12 10:38:24 +03:00
Ari Koivula 0ca65e7606 Move chroma coefficient generation to it's own function.
- It's time to chop up this monster that is encode_transform_tree.
2014-05-12 10:24:06 +03:00
Ari Koivula 3c3c9a26c6 Move scan order selection to a function. 2014-05-12 08:47:16 +03:00

Ari Koivula 93141c7d2e Avoid unnecessary copying of predicted pixels when there are no coeffs.
- These are probably from a time when reconstruction happened in this
  function.
2014-05-09 16:39:58 +03:00
Ari Koivula 27ab882c25 Clean up coefficient generation. 2014-05-09 16:33:10 +03:00
Ari Koivula ce945ab4ef Handle coefficient initialization better.
- Coefficients are no longer required to be pre-zeroed. The resulting zeroes
  are copied in even in the case where we already know they are all zeroes.

- Move cbf clearing code to only happen at the leaves of the recursion.

Laurent Fasnacht b48a687d3c Restored parallelism, but it will be done in another way... OpenMP is not very efficient in these kind of dynamic situation 2014-05-07 11:55:56 +02:00
Laurent Fasnacht 0e6f1c99fc Refactor picture to remove hidden dependency between slice and tiles
picture.type -> encoder_state->global->pictype
picture.slicetype -> encoder_state->global->slicetype
picture.slice_sao_luma_flag -> 1 (was constant)
picture.slice_sao_chroma_flag -> 1 (was constant)

This may be changed later. For now it's better to avoid having slice related stuff in picture.

Ari Koivula eaf8835bda Add some comments and const qualifiers. 2014-05-06 19:20:38 +03:00
Ari Koivula 3910b7989a Clear old cbf data before recursion in encode_transform_tree.
- Because encode_transform_tree also maintains the CBF data and assumes that
  the CBFs are initially zeroed, calling the function more than once would
  result in incorrect CBF data.
2014-05-06 19:03:29 +03:00
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 d1fbc6dc80 Fix a small memory leak.
- Malloced pointer returned by alloc_yuv_t was not being freed in
  substream_encode.

- Remove use of yuv_t from encode_one_frame, as it's not used there anymore.
2014-04-30 11:15:34 +03:00
Ari Koivula 27b94d4b45 Address gcc -Wtype-limits errors.
- Fixes warnings in #19 and #16.
2014-04-29 09:15:52 +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.

Laurent Fasnacht 5fea5875a5 Huge refactoring
Split some parts of encoder_control into encoder_state

Goal is to allow multiple substreams in the future.
2014-04-22 10:39:12 +02:00
Ari Koivula 88a67a4e49 Fix faulty assert that stops the program from working with inter frames.
- The assert would be true after the next if block, but in it's current place
  it's false.
2014-04-22 10:57:38 +03:00
Ari Koivula 1b437a5989 Address clang-analyzer warnings about garbage values.
- False alarm, but surprisingly difficult to convince clang of that. It
  doesn't seem to understand bit shifts very well.

- Only assert and changing LCU_WIDTH>>depth to width was necessary to satisfy
  clang.

- Closes #35.

Marko Viitanen c38ec1aa10 Added commandline option for RDO (--rd) 2014-04-09 12:29:15 +03:00
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 c5dfcdf3aa Simplify scan mode selection.
- The scan mode selection for chroma was a bit complicated so I checked it
  and it was all unnecessary. The mode selection is the same as for luma.
2014-04-09 10:36:39 +03:00
Ari Koivula 3764688f84 Fix lambda initialization.
- Lambda was initialized before slice type was set in encoder_control.
2014-04-08 16:58:36 +03:00
Ari Koivula 6e0bc655e2 Resolve unused variable warning.
- This unexpectedly changes bitstream, but as that makes no sense, it must be
  because some part of the program uses uninitialized memory.

Laurent Fasnacht 8a14bd3b7b Remove cabac global variable 2014-04-04 14:26:40 +02:00
Laurent Fasnacht 946c815932 init_context directly has a QP parameter, instead of passing an encoder_control*
This makes context less tightly coupled with encoder.

Marko Viitanen b83559d3f3 Use RDO to check for transform skip mode 2014-04-04 13:09:42 +03:00
Ari Koivula b19e4f3f2d Resolve possible uninitialized variable warnings.
- Working towards issue #11.

- Neither variable was actually used as uninitialized.

Ari Koivula d44d1837bb Remove unreferenced parameters.
- Working towards issue #11.

Ari Koivula 46d33d3945 Resolve unsigned/signed mismatch warnings.
- Working towards issue #11.

Ari Koivula 27a3329dfb Remove unreferenced_parameter macro.
- It was a silly hack to selectively silence compiler warnings from VS, but
  there is no point as it causes compiler warnings in GCC.

Marko Viitanen 0da8071300 Changed final cost (and transform skip) error function from SAD to SSD 2014-04-02 14:51:39 +03:00
Marko Viitanen a14fb14e33 Added new commandline parameter --no-transform-skip 2014-04-02 14:49:48 +03:00
Marko Viitanen cfb21c0e4c Implemented transform skipping (for 4x4 blocks)
transform skip vs. normal transform selection criteria might need more work, currently both are calculated for each 4x4 block and SAD+coeff_SSE is compared.
