Movie header box

ISO/IEC 14496-12 - 8.2.2

Fields

full_header: FullBoxHeader

The full box header.

creation_time: u64

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

modification_time: u64

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

timescale: u32

An integer that specifies the time-scale for the entire presentation; this is the number of time units that pass in one second. 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 length of the presentation (in the indicated timescale). This property is derived from the presentation’s tracks: the value of this field corresponds to the duration of the longest track in the presentation. If the duration cannot be determined then duration is set to all 1s.

rate: FixedI32<U16>

Indicates the preferred rate to play the presentation; 1.0 is normal forward playback.

volume: FixedI16<U8>

Indicates the preferred playback volume. 1.0 is full volume.

reserved1: u16

Reserved 16 bits, must be set to 0.

reserved2: u64

Reserved 64 bits, must be set to 0.

matrix: [i32; 9]

Provides a transformation matrix for the video; (u,v,w) are restricted here to (0,0,1), hex values (0,0,0x40000000).

pre_defined: [u32; 6]

Reserved 6 * 32 bits, must be set to 0.

next_track_id: u32

Non-zero integer that indicates a value to use for the track_ID of the next track to be added to this presentation. Zero is not a valid track_ID value. The value of next_track_ID shall be larger than the largest track_ID in use. If this value is equal to all 1s (u32::MAX), and a new media track is to be added, then a search must be made in the file for an unused value of track_ID.

Implementations

impl MovieHeaderBox

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

Creates a new MovieHeaderBox with the specified parameters.

All other fields are initialized to their default values.

Trait Implementations

impl Debug for MovieHeaderBox

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for MovieHeaderBox

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 MovieHeaderBox

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 MovieHeaderBox

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 MovieHeaderBox

fn size(&self) -> usize

Returns the size of the type when serialized.

impl PartialEq for MovieHeaderBox

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

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

where W: Write,

Serialize the value into the given writer.

impl Eq for MovieHeaderBox

impl StructuralPartialEq for MovieHeaderBox
