Creating a Phoenix channel source

Hi! I think the best way for you would be to create the message sink and source yourself, it shouldn't be a lot of work. We were tinkering around with the idea, but we never concluded what such elements should exactly do and how should they work and be interacted with in a generic way, since the use-cases can vary a lot. If you have any questions feel free to ask :)

How do I invoke Pipeline.handle_info from a Phoenix.WebChannel?

to give your child a name that can be used to locate this child you need to explicitly specify it in the child function, otherwise the child will be anonymous. You could specify the name like this:

child(:source, AudioTranscription.Source)

child(:source, AudioTranscription.Source)

and the child would be available under name :source

How do I invoke Pipeline.handle_info from a Phoenix.WebChannel?

Hi @Villain In Glasses All Membrane.Pipeline and Membrane.Element callbacks need to return a tuple of Actions and the next state (as shown here) notify_child is an action, so to use it you need to return it from the handle_info callback. In your case the return value in handle_info should probably look like this:

{[notify_child: {<child_name>, <your_message>}], state}

{[notify_child: {<child_name>, <your_message>}], state}

Thanks to this the specified child will receive the message after the handle_info callback execution finishes

RTSP authentication problem?

Hi @Wojciech Orzechowski, SETUP Message doesn't need to have Session Id set. You can try debugging by basing on our rtsp_to_hls demo and by monitoring your network traffic using tools like Wireshark. Should you have any more questions feel free to ask :)
