From 4e2f4917468526716d76d4f1ad32682c59ab2862 Mon Sep 17 00:00:00 2001 From: nam Date: Thu, 5 Nov 2026 14:51:14 -0600 Subject: [PATCH] Guest page: hear yourself, clearer mute, 'What is happening' log Ideas taken from CurryCaster's guest page: - 'Hear yourself' plays the guest's own mic in their headphones (refused when the headphones box is unticked - it would feed back) - Mute shows a clear 'the show cannot hear you' state - 'What is happening' log: connection events plus stats every 15 s in both directions (kb/s, loss, jitter, buffer, concealment, round trip, candidate types). Never includes IP addresses. Kept in the page only; the guest presses Copy and sends it to the host.
