Expand description

Information about a stream offered within a presentation. Currently if multiple formats are offered, this only describes the first.

Fields

media: String

Media type, as specified in the IANA SDP parameters media registry.

encoding_name: String

An encoding name, as specified in the IANA media type registry, with ASCII characters in lowercase.

Commonly used but not specified in that registry: the ONVIF types claimed in the ONVIF Streaming Spec:

vnd.onvif.metadata
vnd.onvif.metadata.gzip,
vnd.onvif.metadata.exi.onvif
vnd.onvif.metadata.exi.ext

rtp_payload_type: u8

RTP payload type. See the registry. It’s common to use one of the dynamically assigned values, 96–127.

clock_rate: u32

RTP clock rate, in Hz.

channels: Option<NonZeroU16>

Number of audio channels, if applicable (media is audio) and known.

control: Option<Url>

The specified control URL. This is needed with multiple streams to send SETUP requests and interpret the PLAY response’s RTP-Info header. RFC 2326 section C.3 says the server is allowed to omit it when there is only a single stream.

Implementations

impl Stream[src]

pub fn parameters(&self) -> Option<&Parameters>[src]

Returns the parameters for this stream.

Returns None on unknown codecs, bad parameters, or if parameters aren’t specified via SDP. Some codecs allow parameters to be specified in-band instead.
