Convert any file VLC can play to mp3

I just felt the need for a script that could extract the audio track of a video, transcode it and save it as an mp3 file … 2 hours later I was finished (get the Gist). 😀 It uses VLC to do hard work. 😉

Thanks to Kris Hom for the inspiration. 🙂

Update 2014-03-01:

  • Check whether VLC is installed
  • Should also work on Linux now
  • Increase default bit rate to 192kbit/s
  • Fixed bug where the file/playlist would repeat endlessly

Update 2014-11-05:

  • Also look for VLC in “~/Application/”

Render Rails assets to string

If you ever needed a way to render a Rails assets to a string, Hongli Lai from Phusion describes how. 🙂

I prepared a Gist wrapping it into a nice helper. 😀

module ApplicationHelper
  # thanks to http://blog.phusion.nl/2011/08/14/rendering-rails-3-1-assets-to-string/
  # you may need to change the owner of the tmp/cache/* directories to the web servers user
  # e.g. for Debian systems: `chown -R www-data:www-data tmp/cache/*`
  def render_asset(asset)
    Conferator::Application.assets.find_asset(asset).body.html_safe
  end
end
