Struct RemoteMedia 

pub struct RemoteMedia {
    pub addr: IpAddr,
    pub port: u16,
    pub payload_type: u8,
    pub codec: Option<AudioCodec>,
    pub opus_payload_type: Option<u8>,
    pub dtmf_events: Vec<DtmfSpec>,
}

Remote media info extracted from an SDP body.

Fields

addr: IpAddr

Remote IP from the c= line.

port: u16

Remote RTP port from the m=audio line.

payload_type: u8

First (preferred) RTP payload type from the m=audio line, raw. Kept for logging/diagnostics; consumers should act on [codec] (Self::codec), which resolves dynamic payload types.

codec: Option<AudioCodec>

The first payload type on the m=audio line that resolves to a codec this stack knows (static 0/8, or a dynamic PT whose rtpmap names opus/48000 or PCMU/PCMA). None when the body offers nothing we understand.

When parsed from an answer this is the negotiated codec. When parsed from an offer it is only the peer’s first preference — the selection is ours to make (select_codec). crate::IncomingCall::accept rewrites this field to the codec it actually selected, so on an established crate::Call it is always the negotiated codec.

opus_payload_type: Option<u8>

The payload type Opus rides on, if Opus appears anywhere in the menu (not just first). This is what lets the answer side prefer Opus over a peer that offers 0 8 111.

dtmf_events: Vec<DtmfSpec>

Every telephone-event entry on the m=audio line, in offer order, with its clock. Use Self::dtmf for “the one that goes with the negotiated codec”.

Implementations

impl RemoteMedia

pub fn dtmf(&self) -> Option<DtmfSpec>

The telephone-event entry to use with the negotiated codec: the one whose clock matches the codec’s RTP clock, else the first offered. None if the remote advertised no telephone-event at all — fall back to SIP INFO for DTMF then.

Trait Implementations

impl Clone for RemoteMedia

fn clone(&self) -> RemoteMedia

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RemoteMedia

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

Formats the value using the given formatter.

impl Eq for RemoteMedia

impl PartialEq for RemoteMedia

fn eq(&self, other: &RemoteMedia) -> 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.
