Struct AbrLadder 

pub struct AbrLadder {
    pub rungs: Vec<AbrRung>,
    pub strategy: AbrStrategy,
    pub max_resolution: (u32, u32),
    pub min_resolution: (u32, u32),
}

ABR ladder configuration.

Fields

rungs: Vec<AbrRung>

The rungs in the ladder, sorted by bitrate (lowest to highest).

strategy: AbrStrategy

Strategy used to generate the ladder.

max_resolution: (u32, u32)

Maximum resolution to include.

min_resolution: (u32, u32)

Minimum resolution to include.

Implementations

impl AbrLadder

pub fn new(strategy: AbrStrategy) -> Self

Creates a new empty ABR ladder.

pub fn add_rung(&mut self, rung: AbrRung)

Adds a rung to the ladder.

pub fn with_max_resolution(self, width: u32, height: u32) -> Self

Sets the maximum resolution.

pub fn with_min_resolution(self, width: u32, height: u32) -> Self

Sets the minimum resolution.

pub fn hls_standard() -> Self

Generates a standard HLS ladder based on Apple recommendations.

pub fn youtube_standard() -> Self

Generates a YouTube-style ABR ladder.

pub fn conservative() -> Self

Generates a conservative ladder (fewer rungs for bandwidth savings).

pub fn aggressive() -> Self

Generates an aggressive ladder (more rungs for quality).

pub fn filter_by_source(self, source_width: u32, source_height: u32) -> Self

Filters rungs based on source resolution.

Only includes rungs at or below the source resolution.

pub fn rung_count(&self) -> usize

Gets the number of rungs in the ladder.

pub fn get_rung(&self, index: usize) -> Option<&AbrRung>

Gets a rung by index.

pub fn highest_quality(&self) -> Option<&AbrRung>

Gets the highest quality rung.

pub fn lowest_quality(&self) -> Option<&AbrRung>

Gets the lowest quality rung.
