      Use source frame difference to make partition decision · 4e66293f
      Yunqing Wang authored 
      Calculate the difference variance between last source frame and
current source frame. The variance is calculated at 16x16 block
level. The variances are compared to several thresholds to decide
final partition sizes.

An adaptive strategy is implemented to decide using
SOURCE_VAR_BASED_PARTITION or FIXED_PARTITION based on motions
in the video. The switching test is done once every
search_type_check_frequency frames.

The selection of source_var_thresh needs to be investigated
further later.

RTC set Borg test showed 0.424% overall psnr gain, and 0.357%
ssim gain. For clips with large enough static area, the
encoding speedup is around 2% to 15%.

      High-level hooks for Profile 2 (10/12 bit) · d35df2d8
      Deb Mukherjee authored 
      Adds some high-level hooks for profile 2 before further
progress on the implementation.

According to the definitiion in this patch:
1. Profile 2 only supports 10 or 12 bit color but not 8
2. Profile 2 supports all color sampling modes: 444, 422 and 420,
and alpha plane.
3. Profile 3 is currently undefined.

Please consider the definition carefully and suggest modifications
to the definition as needed.

      Make last frame source available in current frame encoding · 4a9928e5
      Yunqing Wang authored 
      While encoding a frame, its last frame source can be used to give
acurate motion information. This patch prevents last frame to be
overwritten so that it is available during current frame encoding.

The last source is scaled when it is necessary. cpi->Last_Source
points to the last source frame.

      Enable variable block size test in non-RD mode decision · 60f9ebc3
      Jingning Han authored 
      This is an initial attempt to allow variable block size partition
in non-RD coding flow. It tests 8x8, 16x16 and 32x32 block size per
64x64 block, all using non-RD mode decision and the associated rate
distortion costs from modeling, then selects the best block size to
encode the entire 64x64 block. Such operations are triggered every
other 3 frames. The blocks of intermediate frames will reuse the
collocated block's partition type.

It improves the compression performance by 13.2%. Note that the gains
are not evenly distributed. For many hard clips, the compression
performance is improved by 20% to 28%. Local speed test shows that
it will also increase runtime by 50%, as compared to speed -7. It is
now enabled in speed -6 setting.

      [svc] Finalize spatial svc first pass rate control · d2053350
      Minghai Shang authored 
            1. Save stats for each spatial layer
      2. Add frame buffer management for svc first pass rc
      3. Set default spatial layer to 1
      4. Flush encoder at the end of stream in test app
This only supports spatial svc.
