A transport with only a LiveKit SFU `url` has to be authenticated through
our own homeserver, which needs to know the name of the server owning the
SFU. Carry that name alongside the transport as a TransportLocator,
derived from the member's user ID for remote transports and from the
client's domain for our own, and key the connection map on the SFU URL,
the service URL and the server name together so that `url`, service URL
and combined transport shapes are deduplicated consistently.
UnstableLivekitTransport covers every shape a homeserver may advertise
while MSC4195 evolves: a LiveKit SFU `url`, a `livekit_service_url`, or
both. Switching to it means a service URL is no longer guaranteed, so the
remaining code that relies on one checks for it explicitly: delegation
probing skips transports without one, the connection map keys transports
by whichever URL they carry, and the OpenID flow rejects transports
without a service URL until the client-server API flow lands.
getLocalTransport no longer authenticates with the SFU up front and hands
the resulting config to the connection. Instead the ConnectionManager tags
the connection whose transport equals the local one as the publisher, and
every Connection fetches its own SFU config for its role.
The local member now only joins the MatrixRTC session once its connection
is authenticated, so that the LiveKit room exists before remote members
try to get a subscriber token for it. Subscribers authenticating with the
OpenID flow lack permission to create the room and would otherwise fail
without retrying, causing a cascade of leaves and rejoins at the start of
a call.
The OpenID flow moves to src/livekit/auth/openID.ts with the SFU config
types in a sibling file, takes an options object, and replaces the
MatrixRTC mode with the role we take on the transport plus the session's
slot ID instead of a hard-coded m.call#ROOM.
This changes behaviour: publishers on a livekit_service_url transport
always use the legacy /sfu/get endpoint, so that subscribers can predict
their user:device participant identity, and subscribers always use the
default /get_token endpoint. The MatrixRTC mode no longer influences which
endpoint is used.
- 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.

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
