Struct ProducerReferenceTimeBox

pub struct ProducerReferenceTimeBox {
    pub full_header: FullBoxHeader,
    pub reference_track_id: u32,
    pub ntp_timestamp: u64,
    pub media_time: u64,
}

Producer reference time box

ISO/IEC 14496-12 - 8.16.5

Fields

full_header: FullBoxHeader

The full box header.

reference_track_id: u32

Provides the track_ID for the reference track.

ntp_timestamp: u64

Indicates a UTC time in NTP format associated to media_time as follows:

• if flags is set to 0, the UTC time is the time at which the frame belonging to the reference track in the following movie fragment and whose presentation time is media_time was input to the encoder.
• if flags is set to 1, the UTC time is the time at which the frame belonging to the reference track in the following movie fragment and whose presentation time is media_time was output from the encoder.
• if flags is set to 2, the UTC time is the time at which the following MovieFragmentBox was finalized. media_time is set to the presentation of the earliest frame of the reference track in presentation order of the movie fragment.
• if flags is set to 4, the UTC time is the time at which the following MovieFragmentBox was written to file. media_time is set to the presentation of the earliest frame of the reference track in presentation order of the movie fragment.
• if flags is set to 8, the association between the media_time and UTC time is arbitrary but consistent between multiple occurrences of this box in the same track.
• if flags is set to 24 (i.e. the two bits corresponding to value 8 and 16 are set), the UTC time has a consistent, small (ideally zero), offset from the real-time of the experience depicted in the media at media_time.

media_time: u64

Expressed in the time units used for the reference track.

Trait Implementations

impl Debug for ProducerReferenceTimeBox

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for ProducerReferenceTimeBox

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 ProducerReferenceTimeBox

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 ProducerReferenceTimeBox

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 ProducerReferenceTimeBox

fn size(&self) -> usize

Returns the size of the type when serialized.

impl PartialEq for ProducerReferenceTimeBox

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

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

where W: Write,

Serialize the value into the given writer.

impl Eq for ProducerReferenceTimeBox

impl StructuralPartialEq for ProducerReferenceTimeBox
