Struct TrackSelectionBox

pub struct TrackSelectionBox {
    pub full_header: FullBoxHeader,
    pub switch_group: i32,
    pub attribute_list: Vec<[u8; 4]>,
}

Track selection box

ISO/IEC 14496-12 - 8.10.3

Fields

full_header: FullBoxHeader

The full box header.

switch_group: i32

An integer that specifies a group or collection of tracks. If this field is 0 (default value) or if the TrackSelectionBox is absent there is no information on whether the track can be used for switching during playing or streaming. If this integer is not 0 it shall be the same for 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.

attribute_list: Vec<[u8; 4]>

A list, to the end of the box, of attributes. The attributes in this list should be used as descriptions of tracks or differentiation criteria for tracks in the same alternate or switch group. Each differentiating attribute is associated with a pointer to the field or information that distinguishes the track.

Trait Implementations

impl Debug for TrackSelectionBox

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for TrackSelectionBox

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 TrackSelectionBox

fn deserialize_seed<R>(reader: R, seed: BoxHeader) -> Result<Self>

impl IsoBox for TrackSelectionBox

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 TrackSelectionBox

fn size(&self) -> usize

Returns the size of the type when serialized.

impl PartialEq for TrackSelectionBox

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

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

where W: Write,

Serialize the value into the given writer.
