Opus Specific Box

Encapsulation of Opus in ISO Base Media File Format - 4.3.2

Fields

version: u8

Shall be set to 0.

output_channel_count: u8

Shall be set to the same value as the Output Channel Count field in the identification header defined in Ogg Opus.

pre_skip: u16

Indicates the number of the priming samples, that is, the number of samples at 48000 Hz to discard from the decoder output when starting playback.

input_sample_rate: u32

Shall be set to the same value as the Input Sample Rate field in the identification header defined in Ogg Opus.

output_gain: i16

Shall be set to the same value as the Output Gain field in the identification header define in Ogg Opus.

channel_mapping_family: u8

Shall be set to the same value as the Channel Mapping Family field in the identification header defined in Ogg Opus.

channel_mapping_table: Option<ChannelMappingTable<'a>>

The optional channel mapping table contained in this box.

Only present if channel_mapping_family is not 0.

Trait Implementations

impl<'a> Debug for OpusSpecificBox<'a>

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for OpusSpecificBox<'a>

fn deserialize<R>(reader: R) -> Result<Self>

where R: ZeroCopyReader<'a>,

Deserialize a value from the given zero-copy reader.

impl<'a> DeserializeSeed<'a, BoxHeader> for OpusSpecificBox<'a>

fn deserialize_seed<R>(reader: R, _seed: BoxHeader) -> Result<Self>

where R: ZeroCopyReader<'a>,

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

impl<'a> IsoBox for OpusSpecificBox<'a>

const TYPE: BoxType

The box type of this box.

fn add_header_size(payload_size: usize) -> usize

This function calculates the header size, adds it to the given payload size and return the result.

fn box_header(&self) -> BoxHeader

Constructs a BoxHeader for this box.

fn serialize_box_header<W>(&self, writer: W) -> Result<(), Error>

where W: Write,

Serializes the box header returned by IsoBox::box_header to the given writer.

impl<'a> IsoSized for OpusSpecificBox<'a>

fn size(&self) -> usize

Returns the size of the type when serialized.

impl<'a> PartialEq for OpusSpecificBox<'a>

fn eq(&self, other: &OpusSpecificBox<'a>) -> 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.

impl Serialize for OpusSpecificBox<'_>

fn serialize<W>(&self, writer: W) -> Result<()>

where W: Write,

Serialize the value into the given writer.
