Check whether a Paperclip attachment exists

Don’t simply test for the presence of the magic Paperclip attribute, it will return a paperclip Attachment object and thus always be true:

- if user.photo.present? # always true
  = image_tag(user.photo.url)

  # Run ffmpeg on the video, and do it silently
  ffmpeg_output = `/usr/local/bin/ffmpeg -i "#{video_file}" 2>&1`
	
  # Find the duration in the output, and force a return if it's found
  /duration: ([0-9]{2}:[0-9]{2}:[0-9]{2}.[0-9]{2})/i.match(ffmpeg_output) { |m| return m[1] }

  # If it didn't get a match, something is wrong. Log the error
