open fun getDisplaySize(minVisibleFraction: Float, videoAspectRatio: Float, maxDisplayWidth: Int, maxDisplayHeight: Int): Point

Calculate display size based on minimum fraction of the video that must remain visible, video aspect ratio, and maximum display size.

open fun getDisplaySize(scalingType: RendererCommon.ScalingType, videoAspectRatio: Float, maxDisplayWidth: Int, maxDisplayHeight: Int): Point

open fun getLayoutMatrix(mirror: Boolean, videoAspectRatio: Float, displayAspectRatio: Float): Array<Float>

Returns layout transformation matrix that applies an optional mirror effect and compensates for video vs display aspect ratio.
