Arttu Ylä-Outinen 803f29be8f Remove reconstructed picture allocation in lossless.
Changes encoder_set_source_picture to set the reconstructed picture to
a copy of the source picture instead of allocating a new picture when
lossless coding is used.

Arttu Ylä-Outinen aaec473a19 Refactor encoder state initialization.
- Moves allocation of the reconstructed picture after the source picture
  is set.
- Extracts main state initialization to a separate function from
  encoder_state_new_frame.
- Changes kvz_encoder_feed_frame to return the frame.
- Renames some functions to better match their purpose.

Arttu Ylä-Outinen 06b82bf888 Disable filters, trskip and signhide in lossless.
When lossless coding is used, deblock and SAO are skipped, transform
skip flag is not written and sign hiding is not used.

Arttu Ylä-Outinen 1dc94663c3 Bypass transform and quantization with --lossless.
When --lossless is given, set cu_transquant_bypass_flag for every CU and
bypass transform and quantization by directly copying reference pixels
to reconstruction and the residual to coefficients.

Arttu Ylä-Outinen 2113b0182d Enable PPS-level tq bypass flag with --lossless.
Sets transquant_bypass_enable_flag to true in PPS when --lossless is
given.

Arttu Ylä-Outinen ae832cda8c Pack cbf flags in cu_info_t to two bytes.
Reduces size of cu_info_t.
2016-06-16 20:24:19 +09:00
Arttu Ylä-Outinen cad2d496b8 Enable 4x8 and 4x16 partition modes
Enables search for 2NxN and Nx2N partition modes for 8x8 CUs and 2NxnU,
2NxnD, nLx2N and nRx2N partition modes for 16x16 CUs.

Changes the loop for copying reconstructed luma pixels in
kvz_inter_recon_lcu to use 4 byte chunks instead of 8 byte chunks since
it is now possible to have 4 pixel wide blocks.
2016-06-16 20:23:16 +09:00
Arttu Ylä-Outinen 2ae260e422 Change width of cells in lcu_t to 4 pixels.
Intra mode info for NxN partition units is now stored in the
corresponding 4x4 cell in lcu_t.cu array.

Arttu Ylä-Outinen 46e8122d27 Add functions for indexing cu_array_t structures.
Replaces macro CU_ARRAY_AT with functions kvz_cu_array_at and
kvz_cu_array_at_const.
2016-06-16 18:52:19 +09:00
Arttu Ylä-Outinen 2c85a00a55 Change kvz_cu_array_alloc to use pixel dimensions.
Changes function kvz_cu_array_alloc to take width and height parameters

Arttu Ylä-Outinen b6d793ef33 Drop field inter.mvd from cu_info_t
Instead of storing the mv differences in cu_info_t, they are computed
from the mv candidates and the motion vector. Reduces the size of
cu_info_t.
2016-06-14 12:21:57 +09:00
Arttu Ylä-Outinen ebb10763f1 Drop field inter.mv_ref_coded from cu_info_t.
Storing inter.mv_ref_coded in cu_info_t is unnecessary since it can be
computed from refmap and inter.mv_ref.

Ari Koivula 67acead4bc Fix referring over IDR boundary when using --gop
This problem resulted in an illegal bitstream with --gop=lp, because it
uses IDR's. The --gop=8 would not code IDR pictures, even when told to
with -p, which masked this problem.

This fix solves the problem with --gop=lp and also prevents references
across the intra picture in --gop=8. The intra pictures should be set
to IDR in a later fix, or an alternate method of differentiating
between IDR and non-IDR intra should be made.

Ari Koivula a77dc1610e Refactor encoder_state_remove_refs
I needed to debug this, so I rewrote it to make sense. There is an
obvious bug with the IDR handling that I left in place to fix in a
separate commit.

Ari Koivula 61fc3e87ba Run include-what-you-use fix_includes.py fix_includes.py
The includes should make more sense now and not just happen to compile
due to headers included from other headers.

Used a modified version of IWYU. Modifications were to attribute int8_t
and so on to stdint.h instead of sys/types.h and immintrin.h instead of
more specific headers.

Ari Koivula 674bfa14ce Comment WPP deblocking and SAO
I was a bit unclear about exactly what happens and when regarding SAO
and deblocking when we do frame-parallel WPP parallelism, so I checked
and commented the bits that were unclear to me.

Ari Koivula fd34dd9bc6 Fix race condition with OWF
There was an off by one error in the dependance setting code, which
resulted in dependencies not being set resulting in checksum errors.
For example if ref_neg=1 and owf=1.

Arttu Ylä-Outinen 626b53ce85 Move sao search from encoderstate to sao.
Moves sao search from function encoder_state_worker_encode_lcu in
encoderstate.c to function kvz_sao_search_lcu in sao.c. Makes functions
kvz_init_sao_info, kvz_sao_search_chroma and kvz_sao_search_luma static
since they are no longer used outside sao.c.

Ari Koivula cfa722e448 Reduce parallelism for tiles
There is still some race-condition with encoding tiles from multiple
frames, so disable this to keep the bitstream deterministic.
2016-02-29 20:20:21 +02:00
Ari Koivula b1adf1576a Add --mv-constraint=frametilemargin
Add an even stricter motion vector constraint to prevent motion vectors
to fractional pixel positions that would need pixels outside the tile.
2016-02-29 19:18:14 +02:00
Ari Koivula f808cbf608 Allow increased parallelism for tiles
When movement vectors are constrained to tiles, only the same tile in
previous frame needs to be depended upon.
2016-02-29 14:33:06 +02:00
Ari Koivula c0dc490dd1 Fix inter non-determinism with tiles
CU data was being copied to the wrong place in the reference frames
cu_array, which led to uninitialized data being used as a starting
point for motion vector search.

Fixes #99.
2016-02-26 17:05:04 +02:00
Ari Koivula c40ede56ad Allow more frame parallelism in LP-gop
Add dependency to the reference frame instead of the previous frame,
in order to allow more frames to be encoded in parallel when temporal
stepping >1 in LP-gop (such as --gop=lp-g8d4r1t2).

Arttu Ylä-Outinen 49677810b5 Rename config module to cfg.
Prevents a conflict with config.h and src/config.h so that the config.h
generated by configure is included in global.h. Fixes problems with
large input files on 32-bit systems.
2016-01-25 12:26:46 +02:00
Ari Koivula 947bae24f9 Update Doxygen documentation
Add module information to all header files.

Update all header file documentations to briefly say what they are, and
to use the javadoc format so the brief actually gets included into the
doxygen documentation.

Remove \file from implementation files, in order to not repeat the info
from the header files.

Add files under strategies and tools to Doxygen and update the Doxygen
settings to be just plain better.

Make README be the main page of Doxygen documentation.

Ari Koivula 3a80c7de74 Further optimize coefficient coding
Remove the need to count the coefficients by populating the significant
coefficient group map first and finding the last coefficient from the
last group afterward. The speedup is about 2% on ultrafast.

The previous version of this patch was reverted due to a bug, which
has now been fixed.

Ari Koivula b32965925e Revert "Further optimize coefficient coding"
This reverts commit 25462124f8.

That commit broke the bitstream. If it's not good enough to push on Friday
night, it's probably not good enough on Monday morning either.
