Struct SampleAuxiliaryInformationOffsetsBox

    pub full_header: FullBoxHeader,
    pub aux_info_type: Option<u32>,

Sample auxiliary information offsets box

ISO/IEC 14496-12 - 8.7.9

Fields

full_header: FullBoxHeader

The full box header.

aux_info_type: Option<u32>

An integer that identifies the type of the sample auxiliary information. At most one occurrence of this box with the same values for aux_info_type and aux_info_type_parameter shall exist in the containing box.

aux_info_type_parameter: Option<u32>

Identifies the “stream” of auxiliary information having the same value of aux_info_type and associated to the same track. The semantics of aux_info_type_parameter are determined by the value of aux_info_type.

entry_count: u32

Gives the number of entries in the following table.

For a SampleAuxiliaryInformationOffsetsBox appearing in a SampleTableBox, this shall be equal to one or to the value of the entry_count field in the ChunkOffsetBox or ChunkLargeOffsetBox.

For a SampleAuxiliaryInformationOffsetsBox appearing in a TrackFragmentBox, this shall be equal to one or to the number of TrackRunBoxes in the TrackFragmentBox.

offset: Vec<u64>

Gives the position in the file of the Sample Auxiliary Information for each Chunk or Track Fragment Run. If entry_count is one, then the Sample Auxiliary Information for all Chunks or Runs is contiguous in the file in chunk or run order. When in the SampleTableBox, the offsets are relative to the same base offset as derived for the respective samples through the data_reference_index of the sample entry referenced by the samples. In a TrackFragmentBox, this value is relative to the base offset established by the TrackFragmentHeaderBox in the same track fragment (see 8.8.14).

Trait Implementations

impl Debug for SampleAuxiliaryInformationOffsetsBox

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for SampleAuxiliaryInformationOffsetsBox

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 SampleAuxiliaryInformationOffsetsBox

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 SampleAuxiliaryInformationOffsetsBox

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 SampleAuxiliaryInformationOffsetsBox

fn size(&self) -> usize

Returns the size of the type when serialized.

impl PartialEq for SampleAuxiliaryInformationOffsetsBox

fn eq(&self, other: &SampleAuxiliaryInformationOffsetsBox) -> 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.
