ES Descriptor

ISO/IEC 14496-1 - 7.2.6.5

Fields

es_id: u16

Provides a unique label for each elementary stream within its name scope. The values 0 and 0xFFFF are reserved.

stream_priority: u8

Indicates a relative measure for the priority of this elementary stream. An elementary stream with a higher streamPriority is more important than one with a lower streamPriority. The absolute values of streamPriority are not normatively defined.

depends_on_es_id: Option<u16>

Is the ES_ID of another elementary stream on which this elementary stream depends. The stream with dependsOn_ES_ID shall also be associated to the same object descriptor as the current ES_Descriptor.

url_string: Option<StringCow<'a>>

Points to the location of an SL-packetized stream by name. The parameters of the SL-packetized stream that is retrieved from the URL are fully specified in this ES_Descriptor. See also 7.2.7.3.3. Permissible URLs may be constrained by profile and levels as well as by specific delivery layers.

ocr_es_id: Option<u16>

Indicates the ES_ID of the elementary stream within the name scope (see 7.2.7.2.4) from which the time base for this elementary stream is derived. Circular references between elementary streams are not permitted.

dec_config_descr: DecoderConfigDescriptor<'a>

A DecoderConfigDescriptor.

sl_config_descr: Option<SLConfigDescriptor>

An SLConfigDescriptor.

unknown_descriptors: Vec<UnknownDescriptor<'a>>

A list of descriptors that are contained in this descriptor but not deserialized.

Could be any of:

• IPI_DescrPointer
• IP_IdentificationDataSet
• IPMP_DescriptorPointer
• LanguageDescriptor
• QoS_Descriptor
• RegistrationDescriptor
• ExtensionDescriptor

Implementations

impl ESDescriptor<'_>

pub fn base_descriptor(&self) -> BaseDescriptor

Returns the base descriptor of this ESDescriptor.

Trait Implementations

impl<'a> Debug for ESDescriptor<'a>

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for ESDescriptor<'a>

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

where R: ZeroCopyReader<'a>,

Deserialize a value from the given zero-copy reader.

impl IsoSized for ESDescriptor<'_>

fn size(&self) -> usize

Returns the size of the type when serialized.

impl<'a> PartialEq for ESDescriptor<'a>

fn eq(&self, other: &ESDescriptor<'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 Serialize for ESDescriptor<'_>

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

where W: Write,

Serialize the value into the given writer.
