Struct ChannelLayout 

pub struct ChannelLayout {
    pub order: ChannelOrder,
    pub nb_channels: i32,
    pub channels: Vec<Channel>,
}

Audio channel layout.

Fields

order: ChannelOrder

nb_channels: i32

channels: Vec<Channel>

Implementations

impl ChannelLayout

pub fn mono() -> Self

Mono layout: front center.

pub fn stereo() -> Self

Stereo layout: front left + front right.

pub fn surround_5_1() -> Self

5.1 surround layout.

pub fn surround_7_1() -> Self

7.1 surround layout.

pub fn unspec(nb_channels: i32) -> Self

Unspecified layout with the given channel count.

pub fn from_wav_channel_mask(mask: u32) -> Self

Construct a channel layout from a WAV/WAVEFORMATEXTENSIBLE channel mask.

The WAV channel mask bits correspond to:

• bit 0: FRONT_LEFT
• bit 1: FRONT_RIGHT
• bit 2: FRONT_CENTER
• bit 3: LOW_FREQUENCY
• bit 4: BACK_LEFT
• bit 5: BACK_RIGHT
• bit 6: FRONT_LEFT_OF_CENTER
• bit 7: FRONT_RIGHT_OF_CENTER
• bit 8: BACK_CENTER
• bit 9: SIDE_LEFT
• bit 10: SIDE_RIGHT

impl ChannelLayout

pub fn standard_name(&self) -> Option<&'static str>

Return the FFmpeg standard layout name if this matches a known configuration.

The layout names and channel compositions match FFmpeg’s channel_layout_map table in libavutil/channel_layout.c. Channels are listed in native order (ascending enum/bit-position order).
