Eemeli Kallio ed9c0b0416 RDOQ reworked in rdo.c. rdoq_signhide now skips coeffs that are after best_last_idx. 2016-09-09 10:16:51 +03:00
Ari Koivula 02cd17b427 Add faster AVX inter SAD for 32x32 and 64x64 
Add implementations for these functions that process the image line by
line instead of using the 16x16 function to process block by block.

The 32x32 is around 30% faster, and 64x64 is around 15% faster,
on Haswell.

PASS inter_sad: 28.744M x reg_sad(32x32):x86_asm_avx (1014 ticks, 1.014 sec)

Ari Koivula ec7507a935 Further optimize get_ep_ex_golomb_bitcost 
Unrolled 16-bit log2 calculation.
 2016-08-30 21:37:01 +03:00
Ari Koivula a4ba794587 Optimize get_ep_ex_golomb_bitcost 
Arrange the decision tree such that there is only 3 branches on the
most common paths and the more likely branch is always fall-through.

A profile guided optimization pass would probably do something similar.

Ari Koivula 82cfab58f8 Improve fast mvd coding cost estimation 
A lot of time is being taken up by this function on ultrafast, and it
doesn't do a very good job. This change aims to both simplify the
logic and make the estimate better.

The logic is simplified by using a look up for the step mvd bit cost
step function instead of mimicking the binarization process. The
estimation is made better by checking fractional cabac bit costs.

The new function returns the same results as
kvz_get_mvd_coding_cost_cabac, but is also faster than the old
function.

Ari Koivula 4ec039004b Add monochrome encoding 
Write bitstream without chroma when encoding with --input-format=P400.
This reduces bitstream size by 0-1 %, compared to coding monochrome in
420 format, and speeds up encoding slightly due to not processing
chroma.

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.

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

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

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.

Ari Koivula 3dcc0957f8 Deal with impossible mv constraints 
If 0,0 vector is illegal, it's possible that no legal movement vector,

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.

Ari Koivula 1be877faf9 Fix chroma reconstruction with tiles 
An incorrect frame boundary check caused a checksum error, because the
