This structure describes optional metadata relevant to a downmix procedure.

All fields are set by the decoder to the value indicated in the audio bitstream (if present), or to a “sane” default otherwise.

Fields

preferred_downmix_type: AVDownmixType

Type of downmix preferred by the mastering engineer.

center_mix_level: f64

Absolute scale factor representing the nominal level of the center channel during a regular downmix.

center_mix_level_ltrt: f64

Absolute scale factor representing the nominal level of the center channel during an Lt/Rt compatible downmix.

surround_mix_level: f64

Absolute scale factor representing the nominal level of the surround channels during a regular downmix.

surround_mix_level_ltrt: f64

Absolute scale factor representing the nominal level of the surround channels during an Lt/Rt compatible downmix.

lfe_mix_level: f64

Absolute scale factor representing the level at which the LFE data is mixed into L/R channels during downmixing.

Trait Implementations

impl Clone for AVDownmixInfo

fn clone(&self) -> AVDownmixInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AVDownmixInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for AVDownmixInfo

fn eq(&self, other: &AVDownmixInfo) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
