Membrane element.

element-options

 Element options

Passed via struct Membrane.Testing.Endpoint.t/0

  • autodemand 

    boolean

    Default value: true
    If true element will automatically make demands. If it is set to false demand has to be triggered manually by sending :make_demand message.

  • output 

    {initial_state :: any(), generator} | Enum.t()

    Default value: {0, &Membrane.Testing.Endpoint.default_buf_gen/2}
    If output is an enumerable with Membrane.Payload.t() then buffer containing those payloads will be sent through the :output pad and followed by Membrane.Element.Action.end_of_stream_t/0.

    If output is a {initial_state, function} tuple then the the function will be invoked each time handle_demand is called. It is an action generator that takes two arguments. The first argument is the state that is initially set to initial_state. The second one defines the size of the demand. Such function should return {actions, next_state} where actions is a list of actions that will be returned from handle_demand/4 and next_state is the value that will be used for the next call.

  • caps 

    struct()

    Default value: %Membrane.RemoteStream{content_format: nil, type: :bytestream}
    Caps to be sent before the output.
