NAME¶

libpipewire-module-rtp-sap - SAP Announce and create RTP streams The rtp-sap module announces RTP streams that match the rules with the announce-stream action.

It will create source RTP streams that are announced with SAP when they match the rule with the create-stream action.

If no stream.rules are given, it will announce all streams with sess.sap.announce = true and it will create a receiver for all announced streams.
