Struct ResolutionSelector 

pub struct ResolutionSelector {
    pub max_bandwidth_bps: u64,
    pub min_tier: ResolutionTier,
    pub max_tier: ResolutionTier,
    pub headroom_factor: f64,
}

Selects a resolution tier based on bandwidth or quality constraints.

Fields

max_bandwidth_bps: u64

Maximum available bandwidth in bits per second.

min_tier: ResolutionTier

Minimum acceptable tier.

max_tier: ResolutionTier

Maximum acceptable tier.

headroom_factor: f64

Headroom factor applied to the recommended bitrate when fitting. A value of 1.2 means 20 % safety margin is required.

Implementations

impl ResolutionSelector

pub fn new(max_bandwidth_bps: u64) -> Self

Create a selector with a specific bandwidth ceiling.

pub fn with_min_tier(self, tier: ResolutionTier) -> Self

Set the minimum tier floor.

pub fn with_max_tier(self, tier: ResolutionTier) -> Self

Set the maximum tier ceiling.

pub fn with_headroom(self, factor: f64) -> Self

Set the headroom factor (must be >= 1.0).

pub fn select_for_bandwidth(&self) -> Option<ResolutionTier>

Select the highest tier that fits within the configured bandwidth budget.

Returns None if no tier (not even the minimum) fits.

pub fn select_for_quality(&self) -> ResolutionTier

Select the maximum tier within the configured min/max bounds (ignores bandwidth).

pub fn all_tiers(&self) -> Vec<ResolutionTier>

Return all tiers that fall within the configured min/max bounds.

pub fn abr_ladder(&self) -> Vec<ResolutionTier>

Build an ABR ladder: return all tiers that fit within the bandwidth budget.
