Scale Any #427

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
All scale functions should support 'any' width efficiently.

ScaleDown2 is done.

most scaling is destination size performance sensitive.
keep uv plane subsampling in mind.  odd is size of destination
319x180 uv = 638x360 y.  use this as destination.
source sizes
1276x720 down2
2552x1440 down4
1914x1080 down3
5104x2880 down8

Scale down by 3 uses a general purpose box filter.  For odd width it uses C.  
This test confirms performance:

setlocal
set LIBYUV_WIDTH=1914
set LIBYUV_HEIGHT=1080

set LIBYUV_REPEAT=3999
set LIBYUV_FLAGS=-1

@call :runtest .ScaleDownBy3*

set LIBYUV_WIDTH=1920
set LIBYUV_HEIGHT=1080

set LIBYUV_REPEAT=3999
set LIBYUV_FLAGS=-1

@call :runtest .ScaleDownBy3*

Odd width
ScaleDownBy3_Box (19830 ms)

Even
ScaleDownBy3_Box (6406 ms)
