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.

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.

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.

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.

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.

Arttu Ylä-Outinen 4e5c7fe6e8 Remove function kvz_encoder_compute_stats.

Arttu Ylä-Outinen d5dceb45f1 Factor out a function for building ref lists.
The code for building the reference picture lists was duplicated in
functions encoder_state_ref_sort and print_frame_info. This commit moves
it to a new function kvz_encoder_get_ref_lists. Also makes
encoder_ref_insertion_sort static since it is not used outside the
encoderstate module any more.

Ari Koivula 513e80bcca Fix bug causing unnecessary copying of memory
This bug caused a single tiles worth of lcu_info_t structs to be copied
unnecessarily for every LCU in the frame. This obviously caused huge
memory bandwidth issues when coding large frames without tiles. The
effect was minimized somewhat with a large number of tiles, because
only the current tile was copied.

From context it is clear that this piece of code was supposed to copy
a single tile or frame, once the frame was done, but because it was
placed in a function which is called for every LCU, it copied the data
for the LCU, but also lots of extra stuff.

The fix is to copy only the current LCU instead of the whole tile.

- This type is expected by outside debug scripts. It does not have to
  match the function name.

Arttu Ylä-Outinen 70b3e10e27 Fix a crash with owf=4, gop=8, frames=10.
A call to kvz_threadqueue_waitfor caused the tqj_bitstream_written field
of the previous encoder state to become a dangling pointer, subsequently
causing an assertion to fail. This would only occur when the encoder
state used for a new frame was not the last finished one.

Fixed by setting tqj_bitstream_written to NULL after the job is done and
removing unnecessary calls to kvz_threadqueue_waitfor.

Ari Koivula b2fb1b6d4a Rename kvz_bitstream_align to kvz_bitstream_rbsp_trailing_bits.
- The syntax is called rbsp_trailing_bits in spec and 1 byte is added
  even when the bitstream is already aligned, so align is a bad name.
