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.

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

Ari Koivula 4eaacbe23e Fix bug with lp-gop and ratecontrol
The first frame was always qp51 due to gop_offset being -1 for the
first frame. This fix makes it so that bits are allocated as if it was
the last (high quality) frame from the previous GOP.
2016-05-27 15:53:55 +03:00
Ari Koivula 3fbd7ed97f Add GOP layer weights for lowdelay-P
When using ratecontrol with lowdelay-P, this improves BDRate by 1-25%.
Strongest effect is when using 4 layers and multiple references.

Also allow using 1 or 2 layers with ratecontrol.
2016-05-27 13:46:26 +03:00
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

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 9139e169fe Fix unnecessary waiting in main thread
The main thread has to wait for the worker threads to finish. The
pthread_cond_timedwait call used to accomplish this was given
a relative instead of absolute time, which resulted in the call
returning immediately, because the time had already passed.

This removes the now unnecessary sleeps and fixes the time given to
the pthread_cond_timedwait such that it now waits until a job finishes
or 100ms have passed.

Ari Koivula 1671725c72 Fix non-determinism issue with OWF WPP margin
The previous reasoning used deblocking and fractional motion estimation
together to arrive at a margin of 4 pixels. This was wrong, and with
either of these off, half pixel chroma interpolation could use pixels
outside the intended region.

Deblocking does not currently affect the margin needed.

Ari Koivula 674bfa14ce Comment WPP deblocking and SAO

Ari Koivula 95b8dd99f6 Add --tiles parameter
Add new parameter --tiles that accept only uniform split. I considered
supporting the syntax of --tiles-width-split for this, but writing
--tiles=u2xu2 is just not as intuitive as --tiles=2x2, and there is
hardly ever any reason to use anything but uniform split. The more
cumbersome --tiles-width-split and --tiles-height-split parameters
are still there to allow finer control.

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.

Ari Koivula 81b439f4da Optimize starting point selection in tz
Avoid checking zero motion vectors multiple times. The merge candidate
list often has only one or two candidates, the other being zeroes.

Ari Koivula 5327b59b45 Remove KVZ_PERF_SEARCHPX
It's too invasive and we don't really need it.

Arttu Ylä-Outinen 348ac4888b Fix calc_mode_bits.
The CUs left and above the current one would be set to NULL when there
was only one CU between the current one and the left or top edge of the
frame.

Ari Koivula 86219aa0fc Fix non-determinism with tiles
Earlier fix that fixed the supply side of the cu_array to take tile
coordinates into account should have been accompanied with this one
that does the same thing to demand side.

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 3dcc0957f8 Deal with impossible mv constraints
If 0,0 vector is illegal, it's possible that no legal movement vector,
is found, in which case a large cost is returned instead. The cost
overflowed and there is all sorts of silliness with converting from
double to int, but I'm not going to fix all of it because when we
remove the doubles it will all get fixed.
2016-02-29 19:18:14 +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 f4ebff12b0 Combine tile mv constraint with OWF mv constraint
This also fixes movement vectors in tiles when OWF is on. The OWF mv
constraint assumed WPP, so it didn't work with tiles.

Ari Koivula 1be877faf9 Fix chroma reconstruction with tiles
An incorrect frame boundary check caused a checksum error, because the
chroma reconstruction of the encoder was wrong. The encoder treated
horizontal tile boundaries as frame boundaries when the vertical
component of the movement vector was a multiple of 8.
2016-02-29 14:32:51 +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 719d72925b Add loop-input option
This option is useful for testing long encodes, as you don't have to
find an actual infinite input.

Ari Koivula d23a5a15f1 Fix overflow in rate control
A 32 bit int overflowed after 2^31 bits (2Gb). It will still overflow
eventually, after 500 years of outputting 1Gb/s, but by that time,
I recon we will have fixed this properly and it's time to upgrade.

Ari Koivula eeafe14946 Clean up search initialization
Copy lcu explicitly instead of initializing with the same parameters.

Arttu Ylä-Outinen e5c84c361c Eliminate a race condition with input thread.
Changes communication between the input thread and main thread in
encmain.c so that only one of them uses img_in and retval at a time.
Fixes a race condition which would sometimes result in a deadlock.
2016-02-17 12:09:19 +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).
2016-02-05 17:08:24 +02:00
Arttu Ylä-Outinen 40c7198f7d Add a script for updating README
Adds script tools/update_readme.sh for regenerating the "Using Kvazaar"
section of README.md from the output of "kvazaar --help".

Ari Koivula 7a4bf94a52 Add --version and --help
Also don't print help by default, because it's too long. Print a
shorter usage message instead.

Ari Koivula cb2121b1aa Double time scale when field coding is used 2016-01-28 21:04:52 +02:00
Ari Koivula 8ad7d2a714 Move interlacing stuff to libkvazaaar API
This moves the interlacing from CLI code to api->encoder_encode, in
order to make it possible to use field coding through the lib API.

The field order is now determined per frame, as FFmpeg gives it per
frame and it's signaled per frame.

As a side effect, the CLI also now prints info from frames instead of
fields. While we might want to extend the API in the future to allow
printing of more detailed information about fields, for now it's
more important that the CLI uses the real lib API.

PSNR calculation for interlaced frames disabled until we have a way to
avoid deinterlacing the frame when it's not necessary.

Ari Koivula 6952f0fcc6 Refactor interlaced reading
Doesn't change the way it works. Just rearranges things so it's easier
to see what is going on.

Ari Koivula a46351efe1 Fix out of bounds error in interlacing
When field height was padded to a multiple of 8, yuv_io_extract_field
would read outside the buffer.

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.
