stream RTMP to VLC Network stream

I believe that the idea of RTMP.Sink is to push stream to some endpoint that is already listening for incoming connections

stream RTMP to VLC Network stream

Exactly, using Membrane.RMTP.Sink module was first that came into my mind, however it can be used to push the stream to something that already waiting the stream itself. It worked for me with Youtube. However, we need the ability to send RTMP stream on demand, for instance user clicks the link, we handle this http response adding some Sink to the pipeline and respond user with rtmp url that he can use with ffplay or some other tool

stream RTMP to VLC Network stream

Hey @mat_hek thanks for your answer. Using ffplay to validate the stream is totally fine for our purposes, the thing is that I still getting an error. Currently we run the RTMP server to receive the stream using following code:

handle_new_client = fn client_ref, app, stream_key ->
      Logger.info("New RTMP connection: #{inspect(client_ref)}")
      send(parent_process_pid, {:client_ref, client_ref, app, stream_key})
      Membrane.RTMP.Source.ClientHandlerImpl
    end

{:ok, _server} =
      RTMPServer.start_link(
        handle_new_client: handle_new_client,
        port: Keyword.get(state.opts, :server_port, 1935),
        use_ssl?: Keyword.get(state.opts, :use_ssl?, false)
      )

handle_new_client = fn client_ref, app, stream_key ->
      Logger.info("New RTMP connection: #{inspect(client_ref)}")
      send(parent_process_pid, {:client_ref, client_ref, app, stream_key})
      Membrane.RTMP.Source.ClientHandlerImpl
    end

{:ok, _server} =
      RTMPServer.start_link(
        handle_new_client: handle_new_client,
        port: Keyword.get(state.opts, :server_port, 1935),
        use_ssl?: Keyword.get(state.opts, :use_ssl?, false)
      )

Our pipeline looks following:

child(:rtmp_funnel, Membrane.Funnel),
child(:rtmp_tcp_sink, %Membrane.TCP.Sink{
        connection_side: :server,
        local_address: {127, 0, 0, 1},
        local_port_no: 1937,
        close_on_eos: false,
        on_connection_closed: :drop_buffers
}),
child(:source, %SourceBin{
        client_ref: state.client_ref
      })
|> via_out(:video)
|> get_child(:rtmp_funnel)
|> get_child(:rtmp_tcp_sink),
get_child(:source)
|> via_out(:audio)
|> get_child(:rtmp_funnel)
|> get_child(:rtmp_tcp_sink)

child(:rtmp_funnel, Membrane.Funnel),
child(:rtmp_tcp_sink, %Membrane.TCP.Sink{
        connection_side: :server,
        local_address: {127, 0, 0, 1},
        local_port_no: 1937,
        close_on_eos: false,
        on_connection_closed: :drop_buffers
}),
child(:source, %SourceBin{
        client_ref: state.client_ref
      })
|> via_out(:video)
|> get_child(:rtmp_funnel)
|> get_child(:rtmp_tcp_sink),
get_child(:source)
|> via_out(:audio)
|> get_child(:rtmp_funnel)
|> get_child(:rtmp_tcp_sink)

I assume that this pipeline should pass the payload from the RTMP server through the funnel into :rtmp_tcp_sink which creates a TCP connection on the 1937 port. Using netcat, I see that we are receiving the payload over the TCP Connection, also Membrane Pipeline visualization tool show that TCP Sink processes the data. However, when using ffplay ffplay rtmp://localhost:1937/app/stream1 we get an error:

[rtmp @ 0x60000331ab50] Server response validating failed
rtmp://localhost:1937/app/stream1: Input/output error

[rtmp @ 0x60000331ab50] Server response validating failed
rtmp://localhost:1937/app/stream1: Input/output error

Should I use Membrane.TCP.Sink, or we may consider other library/module/approach for our use case?

Running Docker image with Membrane RTMP Plugin

thanks for quick answer 🙂

membrane_rtmp_plugin uses bundlex under the hood.

membrane_rtmp_plugin uses bundlex under the hood.

Does it mean that BundlexProject module is required to be configured in the application? I am using elixir:1.16.2-otp-26-alpine image. There are no warnings when building rtmp plugin:

#24 149.7 ==> membrane_rtmp_plugin
#24 149.7 Bundlex: Building natives: rtmp_sink
#24 149.9 Compiling 38 files (.ex)

I've seen similar kind of error related to bundlex in this group, however I am not using Bundlex and it seems to be another kind of error.
