Struct HlsMuxer 

pub struct HlsMuxer { /* private fields */ }

Builds one HLS media playlist and returns one Sink per registered track. FFmpeg owns segment boundary selection, fMP4/MPEG-TS creation, atomic playlist replacement, live-window trimming, and final #EXT-X-ENDLIST generation.

This deliberately has the same two-phase shape as crate::elements::Mp4Muxer: call HlsMuxer::add_stream for every track before HlsMuxer::open writes the header. The returned sinks share one output lock and finalize the playlist only after every track reports Eos or ControlMsg::Stop.

Implementations

impl HlsMuxer

pub fn create(options: HlsOptions) -> Result<Self>

Allocates FFmpeg’s HLS output context. Parent directories for the playlist, segment pattern, and fMP4 init file must already exist.

pub fn add_stream( &mut self, name: impl Into<String>, parameters: Parameters, time_base: Rational, ) -> Result<()>

Registers one encoded packet stream. time_base must match the timestamps carried by packets arriving at the returned track sink.

pub fn open(self) -> Result<Vec<Box<dyn Sink>>>

Writes the HLS header and returns one sink per stream, in registration order. The playlist is finalized only after every returned sink has received Eos or ControlMsg::Stop.
