Struct WebmMuxer 

pub struct WebmMuxer<S> { /* private fields */ }

A seekable WebM muxer that writes payload bytes immediately.

Track declarations are the same Mp4TrackConfig values crate::mp4::Mp4Muxer takes, so one encoder configuration feeds either container. Samples from every track are written in one nondecreasing presentation-time order, because a WebM Cluster interleaves its tracks rather than storing each in a run of its own.

Implementations

impl<S: ByteSink> WebmMuxer<S>

pub async fn new( sink: S, configs: Vec<Mp4TrackConfig>, max_samples_per_track: usize, ) -> Result<Self>

pub fn track_count(&self) -> usize

pub async fn write_sample( &mut self, track: usize, sample: EncodedSample, ) -> Result<()>

Writes one sample. A video random-access sample starts a new Cluster and gets a cue point, so every Cluster opens on one; in a file without video, a Cluster opens every few seconds and its first audio block is cued instead. An audio sample is held back until a later sample or Self::finish writes it, so its track’s last block can carry the end padding Self::set_audio_gapless declares.

pub fn set_audio_gapless( &mut self, track: usize, gapless: AudioGapless, ) -> Result<()>

Declares an audio track’s gapless trim and ends the track. The priming must be the delay its codec configuration already declares - an Opus stream’s pre-skip, zero for Vorbis - and the padding is written as the track’s last block’s DiscardPadding, so it has to be set after the track’s last sample and before a sample of another track is written past that sample’s time.

pub async fn finish(self) -> Result<S>
