Sample auxiliary information sizes box

ISO/IEC 14496-12 - 8.7.8

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.

default_sample_info_size: u8

An integer specifying the sample auxiliary information size for the case where all the indicated samples have the same sample auxiliary information size. If the size varies then this field shall be zero.

sample_count: u32

An integer that gives the number of samples for which a size is defined.

For a SampleAuxiliaryInformationSizesBox appearing in the SampleTableBox this shall be the same as, or less than, the sample_count within the SampleSizeBox or CompactSampleSizeBox.

For a SampleAuxiliaryInformationSizesBox appearing in a TrackFragmentBox this shall be the same as, or less than, the sum of the sample_count entries within the TrackRunBoxes of the track fragment.

If this is less than the number of samples, then auxiliary information is supplied for the initial samples, and the remaining samples have no associated auxiliary information.

sample_info_size: Option<BytesCow<'a>>

Gives the size of the sample auxiliary information in bytes. This may be zero to indicate samples with no associated auxiliary information.

If set, length is sample_count.

Trait Implementations

impl<'a> Debug for SampleAuxiliaryInformationSizesBox<'a>

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for SampleAuxiliaryInformationSizesBox<'a>

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

where R: ZeroCopyReader<'a>,

Deserialize a value from the given zero-copy reader.

impl<'a> IsoBox for SampleAuxiliaryInformationSizesBox<'a>

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.

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<'a> IsoSized for SampleAuxiliaryInformationSizesBox<'a>

fn size(&self) -> usize

Returns the size of the type when serialized.

impl<'a> PartialEq for SampleAuxiliaryInformationSizesBox<'a>

fn eq(&self, other: &SampleAuxiliaryInformationSizesBox<'a>) -> bool
