buildVideo
fun buildVideo(description: String, width: Int, height: Int, pixelFormat: PixelFormat, timeBase: Rational, frameRate: Rational, sampleAspectRatio: Rational = Rational(1, 1)): FilterGraph
Builds a single-input video graph from description, for input frames of the given shape.
Parameters
description

width
input frame width
height
input frame height
pixelFormat
input pixel format (e.g. PixelFormat.Yuv420p)
timeBase
pts time-base of input frames
frameRate
frame rate of input, used by setpts/fps-style filters
sampleAspectRatio
SAR of input frames; default 1:1 for square pixels
