Segment index box

ISO/IEC 14496-12 - 8.16.3

Fields

full_header: FullBoxHeader

The full box header.

reference_id: u32

Provides the stream ID for the reference stream; if this SegmentIndexBox is referenced from a “parent” SegmentIndexBox, the value of reference_ID shall be the same as the value of reference_ID of the “parent” SegmentIndexBox.

timescale: u32

Provides the timescale, in ticks per second, for the time and duration fields within this box; it is recommended that this match the timescale of the reference stream or track; for files based on this document, that is the timescale field of the media header box of the track.

earliest_presentation_time: u64

The earliest presentation time of any content in the reference stream in the first subsegment, in the timescale indicated in the timescale field; the earliest presentation time is derived from media in access units, or parts of access units, that are not omitted by an edit list (if any).

first_offset: u64

The distance in bytes, in the file containing media, from the anchor point, to the first byte of the indexed material.

reserved: u16

Reserved 16 bits, must be set to 0.

reference_count: u16

Provides the number of referenced items.

references: Vec<SegmentIndexBoxReference>

The referenced items.

Trait Implementations

impl Debug for SegmentIndexBox

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for SegmentIndexBox

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 SegmentIndexBox

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 SegmentIndexBox

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 SegmentIndexBox

fn size(&self) -> usize

Returns the size of the type when serialized.

impl PartialEq for SegmentIndexBox

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

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

where W: Write,

Serialize the value into the given writer.

impl Eq for SegmentIndexBox
