Struct av_data::audiosample::ChannelMap

pub struct ChannelMap { /* fields omitted */ }

Stores the audio channels in the file in order of occurence

Methods

impl ChannelMap

pub fn new() -> Self

Creates a new channel map

pub fn add_channel(&mut self, ch: ChannelType)

Adds a single channel to the map

pub fn add_channels(&mut self, chs: &[ChannelType])

Adds number of channels to the map in order of occurrence

pub fn len(&self) -> usize

Returns the number of channels in the stream

pub fn is_empty(&self) -> bool

Checks if the channel map is empty

pub fn get_channel(&self, idx: usize) -> ChannelType

Gets the channel type for the channel at the given index

pub fn find_channel_id(&self, t: ChannelType) -> Option<u8>

Finds the first channel index containing a channel of the given type

pub fn default_map(count: usize) -> Self

Creates a default channel map. For 1 channel this is a single centred channel for 2 channels a Right channel and a Left channel. No implementation currently exists for other counts.
