Compact sample to group box

ISO/IEC 14496-12 - 8.9.5

Fields

version: u8

The version of the box.

flags: CompactSampleToGroupBoxFlags

The flags of the box.

grouping_type: [u8; 4]

An integer that identifies the type (i.e. criterion used to form the sample groups) of the sample grouping and links it to its sample group description table with the same value for grouping type. At most one occurrence of either the ‘csgp’ or ‘sbgp’ with the same value for grouping_type (and, if used, grouping_type_parameter) shall exist for a track.

grouping_type_parameter: Option<u32>

An indication of the sub-type of the grouping.

pattern_count: u32

Indicates the length of the associated pattern in the pattern array that follows it. The sum of the included sample_count values indicates the number of mapped samples.

patterns: Vec<CompactSampleToGroupBoxPattern>

pattern_length and sample_count

sample_group_description_index: Vec<Vec<CompactSampleToGroupBoxSampleGroupDescriptionIndex>>

sample_group_description_index[j][k]

See CompactSampleToGroupBoxSampleGroupDescriptionIndex::value for details.

Trait Implementations

impl Debug for CompactSampleToGroupBox

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for CompactSampleToGroupBox

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 CompactSampleToGroupBox

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

where R: ZeroCopyReader<'a>,

impl IsoBox for CompactSampleToGroupBox

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 CompactSampleToGroupBox

fn size(&self) -> usize

Returns the size of the type when serialized.

impl PartialEq for CompactSampleToGroupBox

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

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

where W: Write,

Serialize the value into the given writer.
