Sub track information box

ISO/IEC 14496-12 - 8.14.4

Fields

full_header: FullBoxHeader

The full box header.

switch_group: i16

An integer that specifies a group or collection of tracks and/or sub tracks. If this field is 0 (default value), then there is no information on whether the sub track can be used for switching during playing or streaming. If this integer is not 0 it shall be the same for tracks and/or sub tracks that can be used for switching between each other. Tracks that belong to the same switch group shall belong to the same alternate group. A switch group may have only one member.

alternate_group: i16

An integer that specifies a group or collection of tracks and/or sub tracks. If this field is 0 (default value), then there is no information on possible relations to other tracks/sub- tracks. If this field is not 0, it should be the same for tracks/sub-tracks that contain alternate data for one another and different for tracks/sub-tracks belonging to different such groups. Only one track/sub-track within an alternate group should be played or streamed at any one time.

sub_track_id: u32

An integer. A non-zero value uniquely identifies the sub track locally within the track. A zero value (default) means that sub_track_ID is not assigned.

attribute_list: Vec<u32>

A list, to the end of the box, of attributes. The attributes in this list should be used as descriptions of sub tracks or differentiating criteria for tracks and sub tracks in the same alternate or switch group.

Trait Implementations

impl Debug for SubTrackInformationBox

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for SubTrackInformationBox

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 SubTrackInformationBox

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 SubTrackInformationBox

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 SubTrackInformationBox

fn size(&self) -> usize

Returns the size of the type when serialized.

impl PartialEq for SubTrackInformationBox

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

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

where W: Write,

Serialize the value into the given writer.
