title: Call exiftool from a python script?
body: <p>I'm looking to use exiftool to scan the EXIF tags from my photos and videos. It's a perl executable. What's the best way to inferface with this? Are there any Python libraries to do this already? Or should I directly call the executable and parse the output? (The latter seems dirty.) Thanks.</p>
  
  <p>The reason I ask is this because I am currently using pyexiv2, which does not have support for videos. Perl's exiftool has very broad support for images and videos, and I'd like to use it.</p>
