Struct TrackInfo 

pub struct TrackInfo { /* private fields */ }

One track of a container: its codec, clock, configuration and what the container declares about it. Built with TrackInfo::video, TrackInfo::audio or TrackInfo::other.

Delays and edit offsets are carried untouched, so a stream copy preserves them. They are applied exactly once, by the decoder adapter configured from this track; the session never trims.

Implementations

impl TrackInfo

pub fn video( index: u32, codec: CodecId, time_base: TimeBase, video: VideoTrackInfo, ) -> TrackInfoBuilder

A video track.

pub fn audio( index: u32, codec: CodecId, time_base: TimeBase, audio: AudioTrackInfo, ) -> TrackInfoBuilder

An audio track.

pub fn other( index: u32, kind: TrackKind, codec: CodecId, time_base: TimeBase, ) -> TrackInfoBuilder

A subtitle or data track.

pub fn index(&self) -> u32

The track’s index in its container’s track list.

pub fn kind(&self) -> TrackKind

What the track carries.

pub fn codec(&self) -> &CodecId

The codec.

pub fn time_base(&self) -> TimeBase

The clock its timestamps use.

pub fn codec_private(&self) -> Option<&Arc<[u8]>>

Codec configuration bytes from the container (av1C, avcC, OpusHead), as stored.

pub fn config_epoch(&self) -> u32

The configuration epoch the current codec_private belongs to.

pub fn video_info(&self) -> Option<&VideoTrackInfo>

Video declarations, for a video track.

pub fn audio_info(&self) -> Option<&AudioTrackInfo>

Audio declarations, for an audio track.

pub fn codec_delay(&self) -> Option<FrameDuration>

Decoder delay the container records (Opus pre-skip, AAC priming).

pub fn seek_preroll(&self) -> Option<FrameDuration>

How much must be decoded before a seek target to output it correctly (Opus in WebM: 80 ms).

pub fn edit_delay_ticks(&self) -> Option<i64>

The edit-list offset of the first presentation, in track ticks.

pub fn declared_packets(&self) -> Option<u64>

How many packets the container says the track has.

pub fn declared_duration_ticks(&self) -> Option<u64>

The track length the container declares, in track ticks.
