Struct SampleToGroupBoxEntry

pub struct SampleToGroupBoxEntry {
    pub sample_count: u32,
    pub group_description_index: u32,
}

Entry in SampleToGroupBox.

Fields

sample_count: u32

An integer that gives the number of consecutive samples with the same sample group descriptor. It is an error for the total in this box to be greater than the sample_count documented elsewhere, and the reader behaviour would then be undefined. If the sum of the sample count in this box is less than the total sample count, or there is no SampleToGroupBox that applies to some samples (e.g. it is absent from a track fragment), then those samples are associated with the group identified by the default_group_description_index in the SampleGroupDescriptionBox, if any, or else with no group.

group_description_index: u32

An integer that gives the index of the sample group entry which describes the samples in this group. The index ranges from 1 to the number of sample group entries in the SampleGroupDescriptionBox, or takes the value 0 to indicate that this sample is a member of no group of this type.

Trait Implementations

impl Debug for SampleToGroupBoxEntry

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for SampleToGroupBoxEntry

fn deserialize<R>(reader: R) -> Result<Self>

where R: ZeroCopyReader<'a>,

Deserialize a value from the given zero-copy reader.

impl IsoSized for SampleToGroupBoxEntry

fn size(&self) -> usize

Returns the size of the type when serialized.

impl PartialEq for SampleToGroupBoxEntry

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

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

where W: Write,

Serialize the value into the given writer.
