Composition to decode box

ISO/IEC 14496-12 - 8.6.1.4

Fields

full_header: FullBoxHeader

The full box header.

composition_to_dt_shift: i64

If this value is added to the composition timestamps (as calculated by the CTS offsets from the DTS), then for all samples, their CTS is guaranteed to be greater than or equal to their DTS, and the buffer model implied by the indicated profile/level will be honoured; if leastDecodeToDisplayDelta is positive or zero, this field can be 0; otherwise it should be at least (-leastDecodeToDisplayDelta)

least_decode_to_display_delta: i64

The smallest composition offset in the CompositionOffsetBox in this track.

greatest_decode_to_display_delta: i64

The largest composition offset in the CompositionOffsetBox in this track.

composition_start_time: i64

The smallest computed composition timestamp (CTS) for any sample in the media of this track.

composition_end_time: i64

The composition timestamp plus the composition duration, of the sample with the largest computed composition timestamp (CTS) in the media of this track; if this field takes the value 0, the composition end time is unknown.

Trait Implementations

impl Debug for CompositionToDecodeBox

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for CompositionToDecodeBox

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 CompositionToDecodeBox

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 CompositionToDecodeBox

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 CompositionToDecodeBox

fn size(&self) -> usize

Returns the size of the type when serialized.

impl PartialEq for CompositionToDecodeBox

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

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

where W: Write,

Serialize the value into the given writer.
