bin/mtx-on-ready.sh (runOnReady inside the mediamtx container) posts the is-live notice and, for sources whose audio is not Opus, runs ffmpeg: video copy, audio -> Opus, published over MediaMTX's loopback RTSP to <user>/<Title>.webrtc (record: no). dumpd accepts .webrtc publishes only from 127.0.0.1. The portal hides mirror paths, plays the mirror over WHEP (HLS stays on the source), holds an AAC source for 15 s while its mirror comes up, and corrects the viewer count. Verified headless with a mocked path list. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
