Dear Café, I've created a new package to parse the Extensible Binary Meta Language format using the binary library: https://hackage.haskell.org/package/ebml And I just published a motivating example, an audio broadcasting server for WebSocket clients: https://tristancacqueray.github.io/blog/broadcasting-webm Please let me know if you are interested, contributions and bug reports are welcome! Cheers, -Tristan
