Struct QualityController 

pub struct QualityController { /* private fields */ }

Tracks interaction state and determines encoding parameters each frame.

Implementations

impl QualityController

pub fn new(config: QualityConfig) -> Self

pub fn on_input(&mut self)

Call when any input event is received.

pub fn on_transport_rtt(&mut self, rtt: Duration)

Feed a transport RTT sample into the adaptive quality controller.

pub fn on_network_metrics(&mut self, metrics: NetworkMetrics)

Feed a full network metrics sample into the adaptive quality controller.

The controller treats requested_tier as the application’s preferred maximum quality, and network_cap_tier as the highest quality the current transport conditions can safely sustain.

pub fn requested_tier(&self) -> QualityTier

The currently requested application tier.

pub fn network_cap_tier(&self) -> QualityTier

The highest tier currently allowed by recent network samples.

pub fn current_tier(&self) -> QualityTier

The effective encode tier after combining app preference and network cap.

pub fn last_network_metrics(&self) -> Option<NetworkMetrics>

The most recent network metrics sample, if one has been provided.

pub fn frame_params(&mut self) -> EncodeParams

Get the encode parameters for the current frame.

pub fn set_tier(&mut self, tier: QualityTier)

Set the application’s preferred maximum tier.
