Argument	Description
w	is width to scale down to
h	is height to scale down to.
force_original_aspect_ratio	maintains the input video’s aspect ratio when scaling
format	sets the pixel format of the output video
force_divisible_by	will force the output resolution to be divisible by the defined integer
filterblit	when true enables an FIR filter, it will produce better quality but at a lower performance than the default modified Bresenham filter
keep_alive_timeout	specifies a session keep-alive timeout value. This is a periodic request/response between the libxcoder and the Quadra firmware. When this times-out, the firmware will terminate the filtering instance on the scaler. The Valid range is from 1 to 100 (inclusive).
