Adds a method for determining a fixed size partition based on
variance of a 64x64 SB. This method is added to rtc speed 6.
Also fixes a bug in rtc_use_partition() and includes some
refactoring related to partitioning search, and some cosmetics.

Currently compared to speed 5, the coding efficiency of speed 6
is -19% and that of speed 7 is -55%, in cbr mode.

Only use layered average size if number_temporal_layers > 1.

Also removed unneeded commented-out line, and change some parameter
setting in vpx_temporal_scalable_patterns.c

Change-Id: I8aa3dd068d9a7225b3e8b24392a7b4a54b9435dd

Removes certain cases of feedback of active_worst_quality,
and removes it from the RATE_CONTROL structure. Now active
worst quality is expected to be computed locally in the
q picking function during the encode.
Making temporal filter strength depend on avg_frame_qindex
rather than on active_worst_quality actually improves
performance esp. for yt.
derf: +0.038%
yt: +0.359%

Some parameter changes and fixes on one-pass rate control.
derfraw300 is now only 10% below 2-pass speed 0 rate control.

Change-Id: I1940eef8a5a035dc18e71b880d5e00cabd1f01b9

-Properly set the average frame size for each layer.

-Allow each layer to update its average/last Q stats after encoding.

-Initialize for some layer context variables.

Change-Id: I13738ef1f307cc5f563126bc7a92beaa01fde3bd

Fixes some of the parameters for 1-pass non-cbr mode.
Also includes some cleanups, inlcuding refactoring of the
recode_loop options.

Results on derfraw300 improve by about 5-6%, so that the one-pass
mode is now 13% below the 2-pass mode in speed 0.

Change-Id: I844cc2638694c7574f3be00d41d60b23dc1016f0

This patch adds a buffer-based rate control for temporal layers,
under CBR mode.

Added vpx_temporal_scalable_patters.c encoder for testing temporal
layers, for both vp9 and vp8 (replaces the old vp8_scalable_patterns).

Updated datarate unittest with tests for temporal layer rate-targeting.

Change-Id: I8900a854288b9354d9c697cfeb0243a9fd6790b1

Inlcudes a number cleanups:
1. Moves the one-pass pre-encode parameter setting functions
to vp9_ratectrl.c
2. Deprecates per_frame_bandwidth in RATE_CONTROL structure
3. Removes target_bandwidth in cpi structure since it is not used.
4. Various renaming of functions

There is no bit-stream change in 2-pass, one-pass cbr and one-pass
vbr modes.

Change-Id: Ifd9916bf4d485b7d04c5f52044ffe6703254ccbd

Fixes rate control partially in one-pass non-cbr case to achieve a
bitrate close to the one desired. Previous version was way off at
the high bitrate end.

Also includes several one-pass rate control cleanups and refactoring.

On derfraw300, one-pass encoding is now 19% off from two-pass speed
0 encoding, down from 35%.

silences warnings about declarations not matching prototype

Change-Id: I30b9a24f78ebe3b9cc2bbfcd3a7363ba7c328e4d

Includes a few fixes and clean-ups that adds the ability
to use alt-ref frames in one-pass mode.
Whether alt-refs are actually used or not is controlled by a
macro USE_ALTREF_FOR_ONE_PASS in vp9_firstpass.c.

This first cut seems to improve derf by 15+% in 1-pass mode.
But further experiments with parameters are underway.

Set this_key_frame_forced flag and don't use kf_boost when not set.

Change-Id: Ibe66a82fa9219e60db358ddeb43d6471816c8b50

Fixes assert that fails occasionally on small values of
max-key frame intervals. Also, adds a small change on
updating frames_to_key for frame drops.

Change-Id: Icc2b33b25e3e4ced7e49f8db73e0a887ef9c99e0

Applies an upper limit on burst bitrate for any
frame. This is to insure that typical encodes for YT
do not produce frames that are so large that they
risk stalling HW implementations. Such frames
could also cause playback problems in SW.

For now the limit is set at 250 bits per MB for 1080P
and larger (with the 1080P limit used for smaller frames).

Setting maxQ, constant quality mode or targeting a
very high bandwidth will have precedence over this limit.

Change-Id: I44a89b822a436299b9dd4ff26ad2e35767c29c58

This patch sets frame types correctly in the new
vp9_get_second_pass_params() function called prior
to encode_frame_to_data_rate() function, so that the
latter function can just work with what is passed to
it. This will allow multiple vp9_get_second_pass_params()
to be created for various encode strategies without
messing with the core encode function.

There is no difference in derf and yt. stdhd/hd are pending.

Change-Id: I70dfb97e9f497e9cee04052e0e8e0c2892eab0c3

Various cleanups and streamlining of interfaces as precursor
to further advancements in rate control.
Pre-encode parameter setting for different use cases:
One-pass, first of 2-pass, second of 2-pass, and Svc
are separated out.

There is no change in output with this change.

Change-Id: Ied8ca7d84d610993776aa30ef263fe20452e0e3e

Adjustments based on buffer level, frame dropper.

Change-Id: Iaa85b570493526a60c4b9fb7ded4c0226b1b3a33

Various cleanups and refactoring.
Removes feedback of active worst qaulity and uses last_q
instead to make the interface cleaner. Active worst quality
is now decided only once for a frame being coded in the
beginning based on last_q and other stats. Also, adds other
cleaups on last_q to store also the last_q for altref frames,
and reduces the altref interval a little.

The output does change a little.
derfraw300: +0.224% (global psnr)
stdhdraw250: +0.442% (global psnr)
