AdaptiveStreamPixelDensity class

Controls how a video view's logical size is scaled to physical pixels when computing adaptive-stream dimensions. Mirrors the JS SDK's pixelDensity option (number | 'screen').

Server layers are sized in physical pixels, so on high-density (retina) displays the logical view size under-represents the pixels needed. Set on a view via VideoTrackRenderer; the largest result is requested across all views attached to the track.

Constructors

AdaptiveStreamPixelDensity.fixed(double density): A positive fixed pixel-density multiplier (fractional allowed, e.g. 1.5, 2.0, 2.75). The effective value is capped at maxDensity (3x) when resolved.
const

Properties

hashCode → int: The hash code for this object.
no setteroverride
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
value → double?: Fixed multiplier, or null to use the view's device pixel ratio (auto).
final

Methods

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
resolve(double devicePixelRatio) → double: Resolves the effective multiplier, capped at maxDensity. For auto, falls back to the supplied devicePixelRatio.
toString() → String: A string representation of this object.
override

Operators

operator ==(Object other) → bool: The equality operator.

Constants

auto → const AdaptiveStreamPixelDensity: Use the view's actual device pixel ratio, read via MediaQuery. Equivalent to the JS SDK's 'screen' setting. Capped at maxDensity.
maxDensity → const double: Upper bound applied to the resolved density to keep bandwidth in check.
