Stream Manager

Launch an lk load-test run

Starts a single lk load-test process that simulates many publishers/subscribers in one room. Used by the controller when a test case's browser is set to emulated. Simulcast is enabled by default. Unlike the streamManager path, this does not publish custom/reference media (lk load-test uses its own synthetic clip).

Defaults to "5x5" when omitted (lk load-test itself defaults to "speaker")

participantIdsstring[]

Synthetic participant ids (e.g. "User1", "User2") assigned to this chunk's publishers/subscribers, in order. When Elasticsearch monitoring is enabled, one webrtc-stats document per id is indexed with node_role: browseremulator, matching NORMAL mode's per-participant reporting.
