Use this flag to change the encoder behavior when
SimpleEncode APIs are used
BUG=webm:1733
Change-Id: I9f0852a03ff99faa01cdd8eee8ab71718cc58632
|

Two pass rc parameters are only initialized in the second pass
in vp9 normal two pass encoding.
However, the simple_encode API queries the keyframe group, arf group,
and number of coding frames without going throught the two pass
route.
Since recent libvpx rc changes, parameters in the TWO_PASS
struct have a great influence on the determination of the above
information.
We therefore need to properly init two pass rc parameters in
the simple_encode related environment.

Further changes to normalize the Vizier command line parameters.
The intent is that the default behavior for any given parameter
is signaled by the value 1.0 (expressed on the command line as a
rational).
The final values used in the two pass code are obtained by multiplying
the passed in factors by a default values if use_vizier_rc_params is 1.
Where use_vizier_rc_params is 0 the values are explicitly set to
the defaults.
This patch also changes the default value of each parameter to 1.0
even if not set explicitly. This should ensure safe /default behavior
if the user sets use_vizier_rc_params to 1 but does not set all the
the individual parameters.

If pass --use-vizier-rc-params=1, the rc parameters are overwittern
by pass in values. It --use-vizier-rc-params=0, the rc parameters
remain the default values.

Changes the exposed zm_factor parameter.
This patch alters the meaning of the zm_factor
parameter that will be exposed for the Vizier project.
The previous power factor was hard to interpret in terms
of its meaning and effect and has been replaced by a linear factor.
Given that the initial Vizier results suggested a lower zero motion
effect for all formats, the default impact has been reduced.
The patch as it stands gives a modest improvement for PSNR
but is slightly down on some sets for SSIM
(overall psnr, ssim % bdrate change: -ve is better)
lowres -0.111, 0.001
ugc360p -0.282, -0.068
midres2 -0.183, 0.059
hdres2 -0.042, 0.172

This patch changes the way prediction decay is calculated.
We expect that frames that are further from an ALT-REF frame (or Golden
Frame) will be less well predicted by that ALT-REF frame. As such it is
desirable that they should contribute less to the boost calculation used
to assign bits to the ALT_REF.
This code looks at the reduction in prediction quality between the last
frame and the second reference frame (usually two frames old). We make
the assumption that we can accumulate this to get a proxy for the likely
loss of prediction quality over multiple frames.
Previously the calculation looked at the absolute difference in the
coded errors. The issue here is that the meaning of a unit difference
is not the same for very complex frames as it is for easy frames.
In this patch we scale the decay value based on how the error difference
compares to the overall frame complexity as represented by the intra
coding error.
This was tuned experimentally to give test results that
were approximately neutral for our various test sets. There was
a slight drop in Overall PSNR but a consistent improvement in
SSIM. This balance may be improved with tuning further as it is
noteworthy that it was much better on the hd_res set.
Results (Overall PSNR, SSIM -ve better) for low_res, ugc360, midres2,
ugc480P and hd_res are as follows:
0.173 -0.688
0.118 -0.153
0.132 -0.239
0.261 -0.405
-0.305 -1.109
As part of this adjustment the contribution of motion amplitude was
removed.
This patch also changes the control mechanism that will be exposed
on the command line for use by the Vizier project. The control is now
a linear factor which defaults to 1.0, where values < 1.0 mean a lower
decay rate and values > 1.0 mean an increased decay rate.
This presents a more easily understandable interface for use in
optimizing the decay behavior for various formats, where it is clear
what a passed in value means relative to the default.
With the new decay mechanism the current values for various formats
are almost certainly wrong and we still need to define sensible upper
and lower bounds for use during future training.

Further integration of Vizier adjustable parameters,
This patch connects up additional configurable two pass rate control
parameters for the Vizier project. This still needs to be connected up
to a command line interface and at the moment should still be using
default values that match previous behavior.
Do not submit until verified that defaults are all working correctly.

Send GOP_COMMAND to vp9 for setting gop decisions on the fly.
GOP_COMMAND has three members.
use: use this command to set gop or use vp9's gop decision.
show_frame_count: number of show frames in this gop.
use_alt_ref: use alt ref frame or not.
Move the logic of processing external_arf_indexes_ from
get_gop_coding_frame_num() to GetGopCommand() and
GetCodingFrameNumFromGopMap().

Add coding_index to EncodeFrameInfo
Add start_coding_index to GroupOfPicture
Add frame_coding_index_ to SimpleEncode
The definition of coding index is as follows.
Each show or no show frame is assigned with a coding index based
on its coding order (starting from zero) in the coding process of
the entire video. The coding index for each frame is unique.

Add a MID_OVERLAY_UPDATE abstract to support multi-layer
ARF-Overlay frame based approach. When setting the frame update
type to be USE_BUF_FRAME, the encoder will use show_existing_frame
to process the intermediate ARF frames. When setting the frame
update type to be MID_OVERLAY_UPDATE, the intermediate ARF frames
will go through an overlay frame for display.
