Audio stream loudness base box

ISO/IEC 14496-12 - 12.2.7

Fields

loudness_info_type: Option<u8>

The type of audio scene described by the loudness information. It shall take a value of zero unless other types are supported by the loudness processing. For defined values refer to the corresponding loudnessInfoType specification in ISO/IEC 23008-3.

loudness_base_count: u8

Count of loudness bases in the box.

mae_group_id: Option<u8>

mae_group_ID or mae_group_preset_ID depending on the value of loudness_info_type.

• mae_group_ID is a unique identifier for a group of metadata elements as specified in ISO/IEC 23008-3.
• mae_group_preset_ID is a unique identifier for a group preset as specified in ISO/IEC 23008-3.

loudness_bases: Vec<LoudnessBase>

The loudness bases contained in this box.

Implementations

impl LoudnessBaseBox

pub fn size(&self, version: u8) -> usize

Returns the size of the box in bytes, depending on the version.

Trait Implementations

impl Debug for LoudnessBaseBox

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

Formats the value using the given formatter.

impl<'a> DeserializeSeed<'a, &FullBoxHeader> for LoudnessBaseBox

fn deserialize_seed<R>(reader: R, seed: &FullBoxHeader) -> Result<Self>

where R: ZeroCopyReader<'a>,

Deserialize a value from the given zero-copy reader using the provided seed.

impl PartialEq for LoudnessBaseBox

fn eq(&self, other: &LoudnessBaseBox) -> 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.
