Move session join/leave, track pause/resume, and config error handling out of CallViewModel into the localMembership module. Update developer settings UI, i18n strings, and related RTC session helpers and wiring accordingly. --- locales/en/app.json | 19 +- src/rtcSessionHelpers.ts | 14 +- src/settings/DeveloperSettingsTab.tsx | 71 ++--- src/settings/settings.ts | 18 +- src/state/CallViewModel.ts | 262 ++++--------------- src/state/localMember/LocalMembership.ts | 218 ++++++++++----- src/state/remoteMembers/ConnectionManager.ts | 4 +- 7 files changed, 277 insertions(+), 329 deletions(-) diff --git a/locales/en/app.json b/locales/en/app.json index 11267439..104af750 100644 --- a/locales/en/app.json +++ b/locales/en/app.json @@ -72,12 +72,21 @@ "livekit_server_info": "LiveKit Server Info", "livekit_sfu": "LiveKit SFU: {{url}}", "matrix_id": "Matrix ID: {{id}}", - "multi_sfu": "Multi-SFU media transport", - "mute_all_audio": "Mute all audio (participants, reactions, join sounds)", - "prefer_sticky_events": { - "description": "Improves reliability of calls (requires homeserver support)", - "label": "Prefer sticky events" + "matrixRTCMode": { + "Comptibility": { + "label": "Compatibility: state events & multi SFU" + "description": "Compatible with homeservers that do not support sticky events (but all other EC clients are v0.17.0 or later)", + }, + "Legacy": { + "label": "Legacy: state events & oldest membership SFU" + "description": "Compatible with old versions of EC that do not support multi SFU", + }, + "Matrix_2_0": { + "label": "Matrix 2.0: sticky events & multi SFU" + "description": "Compatible only with homservers supporting sticky events and all EC clients v0.17.0 or later", + } }, + "mute_all_audio": "Mute all audio (participants, reactions, join sounds)", "show_connection_stats": "Show connection statistics", "url_params": "URL parameters" }, diff --git a/src/rtcSessionHelpers.ts b/src/rtcSessionHelpers.ts index 74023c22..a53418f7 100644 --- a/src/rtcSessionHelpers.ts +++ b/src/rtcSessionHelpers.ts @@ -21,6 +21,7 @@ import { ElementWidgetActions, widget } from "./widget"; import { MatrixRTCTransportMissingError } from "./utils/errors"; import { getUrlParams } from "./UrlParams"; import { getSFUConfigWithOpenID } from "./livekit/openIDSFU.ts"; +import { MatrixRTCMode } from "./settings/settings.ts"; const FOCI_WK_KEY = "org.matrix.msc4143.rtc_foci"; @@ -98,9 +99,7 @@ export async function makeTransport( export interface EnterRTCSessionOptions { encryptMedia: boolean; - /** EXPERIMENTAL: If true, will use the multi-sfu codepath where each member connects to its SFU instead of everyone connecting to an elected on. */ - useMultiSfu: boolean; - preferStickyEvents: boolean; + matrixRTCMode: MatrixRTCMode; } /** @@ -112,7 +111,7 @@ export interface EnterRTCSessionOptions { export async function enterRTCSession( rtcSession: MatrixRTCSession, transport: LivekitTransport, - { encryptMedia, useMultiSfu, preferStickyEvents }: EnterRTCSessionOptions, + { encryptMedia, matrixRTCMode }: EnterRTCSessionOptions, ): Promise { PosthogAnalytics.instance.eventCallEnded.cacheStartCall(new Date()); PosthogAnalytics.instance.eventCallStarted.track(rtcSession.room.roomId); @@ -125,10 +124,11 @@ export async function enterRTCSession( const useDeviceSessionMemberEvents = features?.feature_use_device_session_member_events; const { sendNotificationType: notificationType, callIntent } = getUrlParams(); + const multiSFU = matrixRTCMode !== MatrixRTCMode.Legacy; // Multi-sfu does not need a preferred foci list. just the focus that is actually used. rtcSession.joinRoomSession( - useMultiSfu ?
