Ari Koivula f8edf28161 Fix const qualifier warning 
Also set the warning to an error in VS.
 2016-03-09 14:16:15 +02:00
Ari Koivula b0c3ece31e Fix race condition when deblocking is on but SAO is off 
Already suspected this yesterday, but didn't want to add the code to
handle it before confirming that it's actually a problem. It is.
 2016-03-09 14:02:46 +02:00
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.
 2016-03-08 20:18:38 +02:00
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.
 2016-03-08 19:39:04 +02:00
Ari Koivula aec152c953 Fix OWF mv restriction limit 
The check was done in regard to the wrong dimension, allowing the
access to unfinished parts of the frame when coding multiple frames
at the same time.
 2016-03-08 17:12:43 +02:00
Ari Koivula fda103aa7c Refactor cfg->tiles_width_count and cfg->tiles_height_count 
Change code everywere so these actually mean "width count" and not
"width count minus one".
 2016-03-07 17:29:15 +02:00
Ari Koivula a350eb3a1e Fix --tiles to have the correct number of tiles. 
The tiles_width_count etc. actually mean "count minus one".
 2016-03-07 17:24:31 +02:00
Ari Koivula 49ea2d7b7f Fix --mv-constraint=frametile 
Option --mv-constraint=frametilemargin was being used instead of
frametile.
 2016-03-07 16:41:00 +02:00
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.
 2016-03-07 16:33:51 +02:00
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.
 2016-03-07 13:38:23 +02:00
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.
 2016-03-04 16:48:46 +02:00
Ari Koivula 2436702c27 Optimize starting point selection in hexbs 
Avoid checking zero motion vectors multiple times. The merge candidate
list often has only one or two candidates, the other being zeroes.
 2016-03-04 16:48:12 +02:00
Ari Koivula 5327b59b45 Remove KVZ_PERF_SEARCHPX 
It's too invasive and we don't really need it.
 2016-03-04 16:48:12 +02:00
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.
 2016-03-04 14:08:35 +02:00
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.
 2016-03-03 17:39:20 +02:00
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.
 2016-03-01 14:56:16 +02:00
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.
 2016-02-29 14:33:06 +02:00
Ari Koivula 7981609cd0 Add --mv-constraint=frametile 2016-02-29 14:33:06 +02:00
Ari Koivula 9dbbb7fdbc Add --mv-constraint argument 2016-02-29 14:33:06 +02:00
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.
 2016-02-18 20:00:55 +02:00
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.
 2016-02-18 16:48:21 +02:00
Ari Koivula eeafe14946 Clean up search initialization 
Copy lcu explicitly instead of initializing with the same parameters.
 2016-02-17 14:57:31 +02:00
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".
 2016-02-05 16:21:39 +02:00

Set opterr and optind to their normal default values.
 2016-02-04 13:48:58 +02:00
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.
 2016-02-04 13:48:48 +02:00
Ari Lemmetti 99e37ec235 Update old pixel type to the current one 2016-01-30 19:33:09 +02:00
Ari Koivula c76a0951cf Change version to 0.8.3 2016-01-28 21:21:02 +02:00
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.
 2016-01-27 15:29:45 +02:00
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.
 2016-01-26 13:42:41 +02:00
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.
 2016-01-26 13:41:52 +02:00
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 Lemmetti a9decd2f40 Bump for yet another release 2016-01-14 23:23:11 +02:00
Ari Koivula 7718ac378f Add fractional FPS support. 
Now that we put the timing info into the bitstream, the time base must
be precisely known. Represent framerate as a fraction and add timing
info only if the old floating point framerate was not used.

Deprecate cfg->framerate so it can be removed once we get patches to
FFmpeg and libav.

Add support for (num)/(denom) format to --input-fps.

Ari Koivula 1270da3626 Move files under their modules in Visual Studio 
Also moves CLI stuff under CLI project, so they are compiled as their
own lib just like when the Makefile is used.

The file interface_main.c was an artifact from a bygone era and should have
been deleted long ago.
 2015-12-17 15:39:45 +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.
 2015-12-17 14:05:50 +02:00
Ari Koivula a6ea705e19 Add missing lambda to some bit costs 
Bits were being added to rate distortion without being multiplied by
lambda in a few places. Fixing this bug also finally allows us to remove
the magic bits from the Coding Unit split decision.

I tried to find new optimum value for CU_COST and it turned out to be 2
for veryslow and 0 for superfast. The difference between 0 and 2 on
veryslow was only 0.1% however, so I don't think this parameter is
needed any longer. Before this fix the effect of removing CU_COST would
have been 0.8%.

kvz_get_extended_block_generic were too small when the width of the
block was less than its height. Fixed to allocate correctly sized
buffers.

Ari Koivula c94707e6e8 Fix bug with OWF+FME+deblocking 
Increases the MV safety margin of OWF from 2 to 3 when deblocking
is used and 4 when both deblocking and FME are used.

Fractional pixel motion estimation can move the vector one more pixel
down causing checksum error. This fixes that error by increasing the
OWF safety margin and changes the interface, so that different margin
can be used when FME or deblocking are not in use.

Arttu Ylä-Outinen 95fb2ed9ed Fix unexpected behavior of --deblock option. 
Giving a single number as an argument to --deblock option would enable
deblocking and set both beta and tc to that value. This commit changes
a single number argument to be interpreted as a boolean specifying
whether to enable deblocking or not. As a result, "--deblock 0" can be
now used to disable deblocking.

This fixes deblocking being enabled in all presets.

Ari Koivula cd2f1797bf Add reimplemented intra prediction code 
Just along side for now to help with debugging.

The main difference with the new versions is that they take and output
width**2 blocks and two width*2+1 arrays of reference samples,
instead of the (2*width+8)**2 blocks the old ones do. This should make
the interface clearer and the memory footprint smaller.

Also commented the shit out of angular prediction, so hopefully Ari L.
will have an easier time with a SIMD implementation.

The code for building the reference picture lists was duplicated in

it to a new function kvz_encoder_get_ref_lists. Also makes
encoder_ref_insertion_sort static since it is not used outside the

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.

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.
