Bug with Kino.Input.audio when inside a Livebook app

hugobarauna opened this issue · comments

commented

Environment:

  • Livebook from main: 71f6293
  • running with mix phx.server

Using the Kino.Input.audio to record and play audio works just fine inside a regular notebook.

For example, a notebook with just that code:

# Untitled notebook

```elixir
Mix.install(
  [
    {:kino, github: "livebook-dev/kino"},
  ]
)

Section

Kino.Input.audio("Audio")
  • But when I run that as a Livebook app
  • Run the app
  • Record an audio
  • Stop the recording

The app crashes.

Here's a video showing the bug: https://share.cleanshot.com/zbPXFVPc

Here's some part of the error logs:
