As of the removal of 'Legacy' mode, there can no longer be a difference between the transport you advertise in your membership and the transport you publish media on, so the local transport code can be simplified considerably. For instance, the function which gets the local transport can simply return a promise rather than being reactive.
I kept the local transport as an Observable in other modules so that they could easily be tested with existing marble tests.
Extends the [RemoteTracks] logging from #4235 with the per-publication
encryption flag and the ParticipantEncryptionStatusChanged /
EncryptionError room events.
If a publisher encrypts frames while the subscriber believes the
publication is unencrypted, livekit-client bypasses the cryptor and hands
raw ciphertext to the decoder, which is audible as loud noise bursts.
The reverse mismatch (or a missing/invalid key) drops frames instead.
Neither case is visible in a rageshake today.
Warn when ConnectionManagerData merges participants from a second
connection to the same SFU URL, when more than one LiveKit participant
matches a member's backend identity, and when a scope is ended while one
of its behaviors is still delivering a value (which strands the later
bound subscribers on the old value). The per-member match log now also
names the connection the participant came from.
A tile shows "Waiting for media" for as long as its MatrixRTC member
cannot be matched to a LiveKit participant. Log each transition of that
match and of the tile's waitingForMedia state so rageshakes can tie a
stuck tile to the LiveKit participant and track events.
Rageshakes contained nothing about the state of remote tracks, so a tile
showing the wrong mute or video state for a member could not be
diagnosed. Log connect/disconnect, publish/unpublish, subscribe/
unsubscribe, subscription failures, remote mute/unmute and stream state
changes on each Connection's logger, and remove the listeners when the
connection scope ends.
When the ConnectionManager stops a Connection while livekitRoom.connect()
is still pending (which happens on every join, because the local
membership emits twice in quick succession and the connection set is
recomputed), livekit-client rejects the pending connect with "Client
initiated disconnect". Connection.start() then treated that as a failure:
it pushed an UnknownCallError into the state of a connection that was
already stopped and rethrew, and since start() is fire-and-forget the
throw surfaced as
Unhandled promise rejection: Error: Failed to connect to Livekit server
in every rageshake, right after a "livekitRoom.connect FAILED ... Client
initiated disconnect" line. Nothing was actually wrong: the replacement
connection connects fine a moment later.
Mark the connection as stopped before disconnecting, and have start()
return quietly when the rejection is the abort we asked for.
This is the mode in which we sent membership events with the 'oldest membership' transport selection algorithm, which stopped being the default back in version 0.21.0. Users will no longer be able to select this mode in developer settings, and admins will no longer be able to select legacy mode through the config either. The app will still continue to support *receiving* membership events with the 'oldest membership' transport selection algorithm from others, however.
It was rather confusing that matrixLivekitMembers$ gives you objects of type RemoteMatrixLivekitMembers and yet the *local* member would often be among these. I've attempted to clear this up. To my knowledge this wasn't creating any bugs.
I noticed that calls to createDisplayNameBehavior$ and createAvatarUrlBehavior$ were technically leaking resources since they reused the ObservableScope from their outer scope, which in practice lasts for the entire lifetime of the CallViewModel. This would not have had any noticeable effect unless you had other participants leave and rejoin the same call many thousands of times.
- Add camera video quality controls (resolution/framerate/bitrate/codec)
to Settings > Video, mirroring the screen share settings UI
- Add audio processing toggles (echo cancellation, noise suppression,
auto gain control) to Settings > Audio, replacing URL-param-only controls
- Display raw values inline on all sliders (framerate, bitrate, volume)
- Add config-seeded defaults: config.json media_quality values now seed
Setting defaults for users who haven't explicitly set preferences
- Camera settings are applied when joining a call via ConnectionFactory

Add a `media_quality` section to config.json that allows self-hosters
to configure video codec, resolution, bitrate, framerate, and simulcast
layers for both camera and screen sharing.
This addresses the long-standing request in #249 for configurable media
quality settings. The LiveKit SDK already supports all of these options;
this change exposes them through the existing config system.
New config.json fields:
- media_quality.video_codec: preferred codec (vp8/vp9/h264/av1)
- media_quality.video: camera resolution, bitrate, framerate, simulcast layers
- media_quality.screen_share: screen share resolution, bitrate, framerate,
simulcast layers (enables 3+ layer simulcast for screen sharing)
All fields are optional and fall back to the existing defaults (VP8,
720p camera, 1080p screen share) when not specified.

To correctly implement the legacy "oldest membership" mode, we need the code to be more nuanced about the local transport. Specifically, it needs to allow for the transport we advertise in our membership to be different from the transport that we connect to and publish media on. Otherwise, if these two are yoked together, members will resend their memberships whenever an SFU hop occurs, which an attacker could use to cause an amplified wave of state changes.
It's always worth having logs for when state holders are created or destroyed (these are often the most interesting things happening in the application), so I thought it would be nice to have generateItems always log for you when it's doing that.

The local jwt token needs to be aquired via the right endpoint. The
endpoint defines how our rtcBackendIdentity is computed. Based on us
using sticky events or state events we also need to use the right
endpoint. This cannot be done generically in the connection manager. The
jwt token now is computed in the localTransport and the resolved sfu
config is passed to the connection manager.
Add JWT endpoint version and SFU config support Pin matrix-js-sdk to a
specific commit and update dev auth image tag. Propagate SFU config and
JWT endpoint choice through local transport, ConnectionManager and
Connection; add JwtEndpointVersion enum and LocalTransportWithSFUConfig
type. Add NO_MATRIX_2 auth error and locale string, thread
rtcBackendIdentity through UI props, and include related test, CSS and
minor imports updates
