Membrane Core v0.11.0

View Source Membrane.UtilitySupervisor (Membrane Core v0.11.0)

A supervisor that allows to start utility processes under the pipeline's supervision tree.

The supervisor is spawned with each component and can be obtained from callback contexts.

The supervisor never restarts any processes, it just makes sure they terminate when the component that started them terminates. If restarting is needed, a dedicated supervisor should be spawned under this supervisor, like

def handle_setup(ctx, state) do
  Membrane.UtilitySupervisor.start_link_child(
    ctx.utility_supervisor,
    {MySupervisor, children: [SomeWorker, OtherWorker], restart: :one_for_one})
end
