Summary
Adds a new Colibri2 endpoint capability constant,
CAP_RTP_MID_DEMUX_SUPPORT("rtp-mid-demux"), indicating that an endpoint can demux forwarded media by the RTPsdes:midheader extension. Only meaningful together withssrc-rewriting.This is the shared definition for the cross-repo bridge-stamped mid change — the durable fix for the Chrome/WebRTC silent audio-demux wedge under SSRC rewriting. Companion branches named
mid-demux-stampingexist in jitsi-videobridge, jicofo, and lib-jitsi-meet; the Jitsi PR tester builds same-named branches together.Tests
