Struct HlsSegmenter 

pub struct HlsSegmenter<M: Muxer, S: StorageBackend> { /* private fields */ }

Available on crate feature hls only.

Keyframe-boundary HLS segmenter writing through a StorageBackend.

Starts at the first keyframe, cuts a new segment at the first keyframe at or after target_duration seconds, and after each cut writes the media segment and the regenerated index.m3u8 to storage under prefix.

Implementations

impl<M: Muxer, S: StorageBackend> HlsSegmenter<M, S>

pub fn new( muxer: M, storage: S, prefix: impl Into<String>, target_duration: u64, window: usize, ) -> Self

New segmenter writing under prefix, targeting target_duration-second segments and a window-segment live playlist.

pub fn codec_string(&self) -> Option<String>

The HLS CODECS attribute for this rendition’s master-playlist entry.

pub fn low_latency(self, part_target: f64) -> Self

Enable LL-HLS output: the playlist advertises parts and the segmenter emits a partial segment roughly every part_target seconds (writing the part files and #EXT-X-PART/preload-hint lines) in addition to full segments. Requires a muxer that implements take_partial (fMP4 / passthrough).

pub fn playlist_key(&self) -> String

The storage key of the media playlist.

pub fn master_key(&self) -> String

The storage key of the multivariant (master) playlist.

Trait Implementations

impl<M: Muxer, S: StorageBackend> Packager for HlsSegmenter<M, S>

fn push<'life0, 'life1, 'async_trait>( &'life0 mut self, frame: &'life1 MediaFrame, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Feed one frame; may finalize and emit a segment as a side effect.

fn finish<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Flush the final segment and close the rendition.
