Issue Membrane Upgrade to 1.1 (from 0.12.9)
I'm trying to go from Membrane 0.12.9 to 1.1 and hitting a wall. I followed the upgrade guide[1], and everything compiles successfully. Though I'm getting the following error in my pipeline:
```

WebRTC Endpoint + Mixing Multiple Tracks into a single mp4
I have a working app that allows a user to "talk" to an LLM. I'm using Membrane to help coordinate the audio. For QA purposes, we record the tracks (one for each endpoint). I'm trying to setup a bin that mixes the two tracks using the Membrane.LiveAudioMixer so I can have a single file. There's no errors thrown, but the resulting file is only 40 bytes, so I suspect I have something misconfigured.
Each time a pad is added, I try piping it into the LiveAudioMixer and then take that output, encode it and write it to the file.

Loop Audio File
I have a little Membrane Pipeline with a video, and some audio tracks. I want to add some background music to it. A short track, that just loops over and over, until the video is done.
I've looked at doing something like:
```elixir
child(:mp3_source_bg, %Membrane.File.Source{
location: state.background_audio.path,...

Wiring up Javascript FE Using membrane-webrtc-js
Sorry if this obvious. I'm looking through the example in the membrane_rtc_engine (link below). It's not obvious to me how the audio playback for remote endpoints is managed. Does the membrane-webrtc-js take care of that magically? I see
addVideoElement -- but that just seems to add an HTMLVideo element, but doesn't actually connect it to anything from the endpoint / tracks.
https://github.com/jellyfish-dev/membrane_rtc_engine/blob/master/examples/webrtc_videoroom/assets/src/room.ts...Filter with `push` flow_control
Hello, I have a filter that transcribes audio as it receives it by sending it to a transcription service(via a websocket). I also have a VAD filter(applied before the audio data arrives to the Membrane pipeline).
I'm seeing that the audio data only gets sent once the buffer is full(when there is enough voice audio).
I was trying to change the
flow_control to :push for the transcription filter for this. (Is that the right solution?)...LL-HLS broadcasting

Pipeline children started twice
Hello,
I'm seeing children in a Membrane pipeline get started twice:
I think this might be an issue with how I'm starting the pipeline(everytime a websocket connection is created), but I can't figure out exactly why this is happening....
Writing a `Bin` queuing content from multiple remote files

Hello all. New to the framework (and elixir) and still a little fuzzy on how to implement my idea. Basically I want to stitch together a bunch of wav and/or mp3 files and stream them indefinitely. Like a queue where I can keep adding files and the pipeline should grab them as needed FIFO style.
The files will be downloaded via HTTP. So what I'm currently envisioning is a Bin that uses a Hackney source element to grab the file and push it on down. Then, when it's done it will get replaced with a new Hackney source pointing to the next file.

On JF Tracks and Reconnecting (in React)
So I noticed a few things about the react-sdk and JF tracks in general. Note I have react code that works identical to the videoroom demo.
If you're connected to a jellyfish room and then abruptly refresh the browser, a new set of media device ids are created which causes a new set of addTrack calls. I'm not sure if I am doing something wrong or this is intended, but
since new ids are created, new tracks are added to the peer on refresh without being able to remove the old ones since any clean-up code is never fired on refresh. And even when I disconnect gracefully, the removeTrack call fails as described below.
