Struct ChannelLayout 

pub struct ChannelLayout(/* private fields */);

A set of speaker positions; ascending bit order is the interleave order.

Implementations

impl ChannelLayout

pub const MONO: ChannelLayout

Mono: front center only.

pub const STEREO: ChannelLayout

Stereo: front left + right.

pub const SURROUND_5_1: ChannelLayout

5.1 (back): FL FR FC LFE BL BR.

pub const SURROUND_7_1: ChannelLayout

7.1: FL FR FC LFE BL BR SL SR.

pub const fn of(positions: &[ChannelPosition]) -> Self

Layout from a set of positions.

pub const fn default_for(channels: u8) -> Option<Self>

The conventional layout for a channel count (the ffmpeg default-layout table, which the decode path emits): mono, stereo, 2.1, 4.0, 5.0, 5.1, 6.1, 7.1. None for 0 or > 8 channels.

pub const fn channels(self) -> u8

Number of channels in the layout.

pub const fn contains(self, position: ChannelPosition) -> bool

pub const fn index_of(self, position: ChannelPosition) -> Option<usize>

The interleaved channel index of position (its rank among the set bits), or None if the layout lacks it.

pub fn positions(self) -> impl Iterator<Item = ChannelPosition>

The positions in interleave order.
