Struct WebRTCRTPTransceiver 

Source 
pub struct WebRTCRTPTransceiver { /* private fields */ }
Expand description

Mostly matches the WebRTC RTCRtpTransceiver interface.

This is an Abstract Base Class, you cannot instantiate it.

§Properties

§codec-preferences

Caps representing the codec preferences.

Readable | Writeable

§current-direction

The transceiver’s current directionality, or none if the transceiver is stopped or has never participated in an exchange of offers and answers. To change the transceiver’s directionality, set the value of the direction property.

Readable

§direction

Direction of the transceiver.

Readable | Writeable

§kind

The kind of media this transceiver transports

Readable

§mid

The media ID of the m-line associated with this transceiver. This association is established, when possible, whenever either a local or remote description is applied. This field is null if neither a local or remote description has been applied, or if its associated m-line is rejected by either a remote offer or any answer.

§sender

Object
§name

Readable | Writeable | Construct

§parent

The parent of the object. Please note, that when changing the ‘parent’ property, we don’t emit notify and deep-notify signals due to locking issues. In some cases one can use GstBin::element-added or GstBin::element-removed signals on the parent to achieve a similar effect.

§Implements

gst::prelude::ObjectExt, [trait@glib::ObjectExt]

GLib type: GObject with reference counted clone semantics.
