RTCRtpTransceiver: mid property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.
The read-only RTCRtpTransceiver interface's mid property specifies the media ID (mid) which uniquely identifies the stream's pairing of sender and receiver.
Value
A string which uniquely identifies the pairing of source and destination of the transceiver's stream. Its value is taken from the media ID of the SDP m-line. This value is null before a local or remote description containing the corresponding m-line is applied, or if a rollback undoes that association.
