What are you working on? Any new ideas which you're thinking about?

I've been hacking on an Icecast-compatible server with Erlang. You can feed it an FFmpeg icecast feed into the server, and listen to it with any Icecast-compatible player. I think it's kind of neat; I do some extra things that the official Icecast server doesn't give you.

I store the chunks in a custom-built database (on top of riak_core and Bitcask), and I have it automatically also make an HLS stream as well. This involved remuxing the AAC chunks into MPEG-TS and dynamically create the playlist.

It's also horizontally scalable, almost completely linearly. Everything is done with Erlang's internal messaging and riak_core, and I've done a few (I think) clever things to make sure everything stays fast no matter how many nodes you have and no matter how many concurrent streams are running.

This sounds super cool! Any public code you can share?

I’m afraid not; I have become a tiny bit disillusioned with open source and I’m keeping some of my projects to myself now.

I’ll probably release the code I wrote for the input radio station but that’s just a glorified script written in Rust and calling FFmpeg. The only fun part of that is I call OpenAI to get AI commercials and DJ chatter.
