Hi everyone!
Latest update on Membrane Framework for Q4 2019.
The biggest change is the introduction of bins which enables creating reusable modules and further optimizes your workflow with Membrane.
Be also sure to check the new packages.
Let us use this opportunity to wish you all the best in 2020! Enjoy exciting projects, new ventures, happy users and most of all - enjoy using Membrane!

Hi, smolcatgirl here!
I tried setting up something simple with this project to learn about the project and I am getting this error:
== Compilation error in file lib/membrane_test/pipeline.ex ==
** (CompileError) lib/membrane_test/pipeline.ex:24: Membrane.ParentSpec.__struct__/1 is undefined, cannot expand struct Membrane.ParentSpec
when I have this in the pipeline file:
spec = %ParentSpec{
children: children,
links: links
}
In the top of the file I have this line use Membrane.Pipeline. Please help me out here. I also tried changing to %Membrane.ParentSpec{}
Edit: here are my deps
[
{:membrane_core, "~> 0.4.0"},
{:membrane_element_file, "~> 0.2.3"},
{:membrane_element_portaudio, "~> 0.2.3"},
{:membrane_element_ffmpeg_swresample, "~> 0.2.3"},
{:membrane_element_mad, "~> 0.2.3"}
]
Thanks for your time
Hi @smolcatgirl! The Membrane.ParentSpec struct has been introduced in version 0.5.0 of Membrane Core. Bump the dependency and your code should work fine 
EDIT:
Other deps need to be bumped as well, you can check out the updated guide chapter Creating the first pipeline — Membrane Guide v0.5.0 and copy-paste the snippet from there
Hi @mspanc, I was wondering if you had completed work enabling Membrane Elements to be WebRTC peers - I noticed your team’s work here which seems like preparation for it.
Is there anywhere I can track that work (a repo, etc.)? We’re evaluating Membrane for a large many party audio conferencing solution and I’d love to take a look, contribute, etc.
Really enjoyed your talk at the BEAM conference last year, thanks so much for your work!
Hi @ben-pr-p, we’re closer than ever to be able to use Membrane as WebRTC peers. Many parallel elements (SRTP, Opus etc…) are in progress, and most of them are in the very last stage.
Right now, we do not have any publicly available tracker that would have clearly shown progress when it comes to the WebRTC but I think we might prepare such summary soon.
Thanks 
Hi people, sorry if it was already explained or pointed out but am planning to create a web app that enables people to created a room, add people and play using video and audio. I don’t want to go for any of the actual solutions and would like to make my own server to process media. How can I see an example using Membrane?
Thanks!
Hi @gastonrey, if the app is supposed to work in the browser, you most likely need to use WebRTC protocol. If the rooms you mentioned are going to be quite small (at most up to ~10 people) and you need no server-side processing, Membrane WebRTC signalling server is a way to go. Otherwise, you need a WebRTC gate to connect the server as a peer. The gate is quite a big thing and we’re still working on it. For now, you can try to integrate a non-membrane solution, such as Janus, however it may be quite cumbersome.
By the way, we’re currently working on an open-source toolkit that is based on Membrane and Janus and is kind of “starter kit” for creating a conference or webinar application.
It should handle all the hard things mentioned by @mat-hek and in the talk he referenced.
If you can wait 2-3 weeks you should be able to use it as a basis for you application.
