XML metadata sample entry

ISO/IEC 14496-12 - 12.3.3

Fields

sample_entry: MetaDataSampleEntry

The sample entry that this box inherits from.

content_encoding: Utf8String

A MIME type which identifies the content encoding of the timed metadata. It is defined in the same way as for an ItemInfoEntry in this document. If not present (an empty string is supplied) the timed metadata is not encoded. An example for this field is ‘application/zip’. Note that no MIME types for BiM [ISO/IEC 23001-1] and TeM [ISO/IEC 15938-1] currently exist. Thus, the experimental MIME types ‘application/x-BiM’ and ‘text/x-TeM’ shall be used to identify these encoding mechanisms.

namespace: Utf8List

One or more XML namespaces to which the sample documents conform. When used for metadata, this is needed for identifying its type, e.g. gBSD or AQoS [MPEG-21-7] and for decoding using XML aware encoding mechanisms such as BiM.

schema_location: Utf8List

Zero or more URLs for XML schema(s) to which the sample document conforms. If there is one namespace and one schema, then this field shall be the URL of the one schema. If there is more than one namespace, then the syntax of this field shall adhere to that for xsi:​schemaLocation attribute as defined by XML. When used for metadata, this is needed for decoding of the timed metadata by XML aware encoding mechanisms such as BiM.

btrt: Option<BitRateBox>

The contained BitRateBox. (optional)

unknown_boxes: Vec<UnknownBox<'a>>

A list of unknown boxes that were not recognized during deserialization.

Trait Implementations

impl<'a> Debug for XMLMetaDataSampleEntry<'a>

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for XMLMetaDataSampleEntry<'a>

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 XMLMetaDataSampleEntry<'a>

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<'a> IsoBox for XMLMetaDataSampleEntry<'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.

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<'a> IsoSized for XMLMetaDataSampleEntry<'a>

fn size(&self) -> usize

Returns the size of the type when serialized.

impl<'a> PartialEq for XMLMetaDataSampleEntry<'a>

fn eq(&self, other: &XMLMetaDataSampleEntry<'a>) -> 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<'a> Serialize for XMLMetaDataSampleEntry<'a>

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

where W: Write,

Serialize the value into the given writer.
