View Source Membrane.UtilitySupervisor (Membrane Core v1.1.1)

A supervisor responsible for managing utility processes under the pipeline's supervision tree.

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

Membrane.UtilitySupervisor does not restart processes. Rather, it ensures that these utility processes terminate gracefully when the component that initiated them terminates.

If a process needs to be able to restart, spawn a dedicated supervisor under this supervisor.

Example

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