Struct ChannelLayout 

pub struct ChannelLayout {
    pub nb_channels: usize,
    pub nb_streams: usize,
    pub nb_coupled_streams: usize,
    pub mapping: Vec<u8>,
}

How the channels of a multistream signal map onto mono and stereo (coupled) Opus streams (RFC 7845 channel mapping).

Fields

nb_channels: usize

Total output channels.

nb_streams: usize

Number of Opus streams in each packet.

nb_coupled_streams: usize

How many of those streams are stereo (coupled); they come first.

mapping: Vec<u8>

For each output channel, the decoded channel index it takes.

Implementations

impl ChannelLayout

pub fn surround(channels: usize, mapping_family: i32) -> Result<Self, Error>

Standard layout for a channel count + mapping family (0 = mono/stereo, 1 = Vorbis surround for 1..=8 channels).

Errors

Error::BadArg if mapping_family is not 0 or 1, or channels is out of range for it (1–2 for family 0, 1–8 for family 1).

Trait Implementations

impl Clone for ChannelLayout

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
