Struct AbrLadder 

pub struct AbrLadder {
    pub renditions: Vec<ResolutionBitrate>,
}

An adaptive bitrate ladder containing multiple renditions.

Fields

renditions: Vec<ResolutionBitrate>

Renditions sorted by bitrate descending.

Implementations

impl AbrLadder

pub fn new(renditions: Vec<ResolutionBitrate>) -> Self

Creates a new ABR ladder.

pub fn optimal_bitrate_kbps( &self, bandwidth_kbps: u32, ) -> Option<&ResolutionBitrate>

Selects the optimal rendition for a given available bandwidth.

Returns the highest-bitrate rendition whose bitrate is ≤ 80% of available bandwidth.

pub fn len(&self) -> usize

Returns the number of renditions in the ladder.

pub fn is_empty(&self) -> bool

Returns true if the ladder has no renditions.

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

Returns the highest-quality rendition.

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

Returns the lowest-quality rendition.
