pub struct CodecNegotiation { /* private fields */ }
Expand description

Selects a codec and a set of capabilities for that codec, based on a preferential list of partially-defined codec capabilities, using each codec’s support to find best compatable matching capability. Currently supports SBC and AAC codec capabilities.

Implementations§

source§

impl CodecNegotiation

source

pub fn build( codecs: Vec<ServiceCapability>, direction: EndpointType ) -> Result<Self>

Make a new codec negotiation set using codecs as an ordered list “ideal” capabilities. Capabilities earlier in the list are preferred if compatible when selecting. When selecting endpoints, ones of direction are chosen over ones other directions. Returns an error if any of the capabilities provided can’t be negotiated, or aren’t codecs.

source

pub fn select( &self, endpoints: &[StreamEndpoint] ) -> Option<(Vec<ServiceCapability>, StreamEndpointId)>

Given a set of endpoints, return the endpoint id, and the ServiceCapabilities we should request when configuring that endpoint for streaming, based on our preferences for codecs and delay reporting. Returns None if none of the endpoints can be supported by the supported codecs.

source

pub fn select_codec( &self, endpoints: &[StreamEndpoint] ) -> Option<(ServiceCapability, StreamEndpointId)>

Given a set of endpoints, return the endpoint id, and a ServiceCapability representing the selected compatible codec parameters for that endpoint, based on our preferences. Returns None if none of the endpoints can be supported by the preferred codecs.

source

pub fn set_direction(&mut self, direction: EndpointType)

Change the preferred direction. Calls to select after this call will prefer to match endpoints that are of direction

source

pub fn direction(&self) -> EndpointType

Returns the currently preferred direction
