A Representation describes a version of the content, using a specific encoding and bitrate.

Streams often have multiple representations with different bitrates, to allow the client to select that most suitable to its network conditions (adaptive bitrate or ABR streaming).

Fields

id: Option<String>

bandwidth: Option<u64>

The average bandwidth of the Representation.

qualityRanking: Option<u8>

Specifies a quality ranking of this Representation relative to others in the same AdaptationSet. Lower values represent higher quality content. If not present, then no ranking is defined.

dependencyId: Option<String>

Identifies the base layer representation of this enhancement layer representation. Separation between a base layer and a number of enhancement layers is used by certain content encoding mechanisms, such as HEVC Scalable and Dolby Vision.

associationId: Option<String>

associationType: Option<String>

mediaStreamStructureId: Option<String>

profiles: Option<String>

width: Option<u64>

height: Option<u64>

sar: Option<String>

The Sample Aspect Ratio, eg. “1:1”.

frameRate: Option<String>

audioSamplingRate: Option<String>

mimeType: Option<String>

segmentProfiles: Option<String>

Specifies the profiles of Segments that are essential to process the Representation. The semantics depend on the value of the @mimeType attribute.

codecs: Option<String>

A “remote resource”, following the XML Linking Language (XLink) specification. An RFC6381 string, https://tools.ietf.org/html/rfc6381

containerProfiles: Option<String>

maximumSAPPeriod: Option<f64>

startWithSAP: Option<u64>

maxPlayoutRate: Option<f64>

Indicates the possibility for accelerated playout allowed by this codec profile and level.

codingDependency: Option<bool>

scanType: Option<String>

If present, this attribute is expected to be set to “progressive”.

selectionPriority: Option<u64>

tag: Option<String>

contentType: Option<String>

lang: Option<String>

Language in RFC 5646 format.

sampleRate: Option<u64>

numChannels: Option<u32>

href: Option<String>

actuate: Option<String>

scte214_supplemental_profiles: Option<String>

scte214_supplemental_codecs: Option<String>

FramePacking: Vec<FramePacking>

AudioChannelConfiguration: Vec<AudioChannelConfiguration>

ContentProtection: Vec<ContentProtection>

OutputProtection: Option<OutputProtection>

essential_property: Vec<EssentialProperty>

supplemental_property: Vec<SupplementalProperty>

InbandEventStream: Vec<InbandEventStream>

Switching: Vec<Switching>

group_label: Vec<Label>

Label: Vec<Label>

ProducerReferenceTime: Vec<ProducerReferenceTime>

Resync: Vec<Resync>

BaseURL: Vec<BaseURL>

SubRepresentation: Vec<SubRepresentation>

SegmentBase: Option<SegmentBase>

SegmentList: Option<SegmentList>

SegmentTemplate: Option<SegmentTemplate>

representation_index: Option<RepresentationIndex>

Trait Implementations

impl Clone for Representation

fn clone(&self) -> Representation

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Representation

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

Formats the value using the given formatter.

impl Default for Representation

fn default() -> Representation

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Representation

where Representation: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Representation

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

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Representation
