title: Rails 3.2/Heroku issue - Precompiling .mp4 videos in public/videos
body: <p>New to rails here:
  I have a rails app and I'd like to place videos on a page or two using html5 video tags. I am currently using Rails 3.2 and Heroku's cedar stack to deploy my app. I am running into an issue when deploying my app to Heroku. </p>
  
  <p>I have placed my .mp4 videos in <strong>public/videos</strong>, and when running rails' local server, everything works just fine. </p>
  
  <p>However, when I deploy to heroku, the pages containing these videos do not load, i.e. "We're sorry but something went wrong". 
  Checking the logs</p>
  
  <pre><code>heroku logs
  </code></pre>
  
  <p>shows this error</p>
  
  <pre><code>ActionView::Template::Error (car_circle.mp4 isn't precompiled)
  </code></pre>
  
  <p>this isn't too surprising, since it seems the public folder isn't included in the rails 3.2 asset pipeline, and so everything in there doesn't get precompiled.</p>
  
  <p>If my reasoning here is correct, I'd like to know how I can get public/videos included in my asset pipeline, so that these videos can be precompiled. Alternately, if I shouldn't have these videos in /public, some guidance on how to correctly move them into the asset pipeline would be great as well.</p>
  
  <p>Hope I've provided enough information for you all to give me a hand. Thanks.</p>
