Struct MediaHeaderBox

    pub full_header: FullBoxHeader,
    pub creation_time: u64,
    pub modification_time: u64,

Media header box

ISO/IEC 14496-12 - 8.4.2

Fields

full_header: FullBoxHeader

The full box header.

creation_time: u64

An integer that declares the creation time of the media in this track (in seconds since midnight, Jan. 1, 1904, in UTC time).

modification_time: u64

An integer that declares the most recent time the media in this track was modified (in seconds since midnight, Jan. 1, 1904, in UTC time).

timescale: u32

An integer that specifies the number of time units that pass in one second for this media. For example, a time coordinate system that measures time in sixtieths of a second has a time scale of 60.

duration: u64

An integer that declares the duration of this media (in the scale of the timescale) and should be the largest composition timestamp plus the duration of that sample. If the duration cannot be determined then duration is set to all 1s.

language: Langauge

Declares the language code for this media, as a packed three-character code defined in ISO 639-2.

pre_defined: u16

Pre-defined 16 bits, must be set to 0.

Implementations

impl MediaHeaderBox

pub fn new( creation_time: u64, modification_time: u64, timescale: u32, duration: u64, ) -> Self

Creates a new MediaHeaderBox with the specified parameters.

All other fields are set to their default values.

Trait Implementations

impl Debug for MediaHeaderBox

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for MediaHeaderBox

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 MediaHeaderBox

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 IsoBox for MediaHeaderBox

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<()>

where W: Write,

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

impl IsoSized for MediaHeaderBox

fn size(&self) -> usize

Returns the size of the type when serialized.

impl PartialEq for MediaHeaderBox

fn eq(&self, other: &MediaHeaderBox) -> 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 MediaHeaderBox

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

where W: Write,

Serialize the value into the given writer.
