setMaxSelectableVideoQualityForViewportSize
Provides the video viewport size to the player. The player will constrain the automatic quality selection, such that the maximum selectable resolution is close to the view port size. This might include qualities that have a slightly higher resolution than the view port. This does not affect the Source.availableVideoQualities nor the Source.setVideoQuality calls i.e. this call has no effect on manual quality selection.
PlayerView can be configured to automatically set the viewport size based on it's size by setting PlayerViewConfig.playerMaxVideoQualityConstraint to PlayerVideoQualityConstraint.RelaxedViewport.
Both values can be set to Integer.MAX_VALUE for no limitation.
Has no effect if there is no active playback session.
