Port of edf1feae from johannes/rtc-remote-publish onto the SDK split,
where
the MatrixRTC logic lives in sdk/ rather than src/state/CallViewModel/.
Where the original lands:
- getLocalTransport's remote fallback: the LiveKit backend's new
findRemotePublishTransport (sdk/src/media-backend/livekit/
RemotePublishTransport.ts), which tries the candidates from the
js-sdk's
getRemoteLivekitPublishCandidates oldest first and keeps the first
whose
homeserver issues a token with the publish grant.
discoverLocalTransport
asks the backend for it after the host's fallback, with a snapshot of
the
session's memberships from RTCParticipation, and throws
MatrixRTCTransportMissingError where that finds nothing too. Transport
discovery stays backend neutral: the MSC4195 token check is the
backend's.
- LocalMember's "no delegation on a remote SFU" and the custom
transport's
server_name: LivekitBackend.prepareLocalTransport locates the
transport on
the homeserver it names (serverNameOfTransport) and skips the
delegation
probe where that is not our own.
- SessionBehaviors' membership.getTransportServerName: the same helper
in
LivekitBackend.mediaFor.
- decodeSFUJWTPayload, SFUJWTPayload.video.canPublish and the exported
isCsApiUnavailable: sdk/src/media-backend/livekit/auth/.
- DeveloperSettingsTab, the widget capabilities, the locale string and
the
js-sdk pin (9405287c, 44.0.0): applied as is. The error boundary
snapshots follow the string.
Tests: the LocalTransport cases go to RemotePublishTransport.test.ts and
LocalTransport.test.ts, the LocalMember remote case and the
SessionBehaviors
server-name case to LivekitBackend.test.ts, plus the memberships
snapshot in
RTCParticipation.test.ts.
