      vp9_satd: return an int · 3e0138ed
      James Zern authored 
      the final sum may use up to 26 bits

+ add a unit test
+ disable the sse2 as the result will rollover; this will be fixed in a
future commit

      On Nexus 7 speed -5, -6, -7, and -8 saw about a 1% increase
in perf for 480p. Speeds -5, -6, -7, and -8 saw about a 1.5%
increase in perf for 720p.

Tested on Nexus 7, built with ndk r10d, gcc 4.9.

      Enable non-rd mode coding on key frame, for speed 6. · 8fd3f9a2
      Marco authored 
      For key frame at speed 6: enable the non-rd mode selection in speed setting
and use the (non-rd) variance_based partition.

Adjust some logic/thresholds in variance partition selection for key frame only (no change to delta frames),
mainly to bias to selecting smaller prediction blocks, and also set max tx size of 16x16.

Loss in key frame quality (~0.6-0.7dB) compared to rd coding,
but speeds up key frame encoding by at least 6x.
Average PNSR/SSIM metrics over RTC clips go down by ~1-2% for speed 6.

      experimental : partition using 1/8 x 1/8 image · 0ce51d82
      Jim Bankoski authored 
      The concept:

There's too much noise in source pixels for variance and at low bitrate
the reconstructed looks nothing like the source so we have problems
getting good partitionings with either.   This skirts the issue by using
a box blur scaled down version for variance calculations.  To compare
against source_var_ moved keyframe to be rd based like source_var.
