Hi Guys,

I'm using SWFUpload and Paperclip on Rails 2.3.5 to upload images and videos. How can I store the capture date of images and duration of videos?

The following works correctly in irb:

irb(main):001:0> File.new('hatem.jpg').mtime
=> Tue Mar 09 16:56:38 +0200 2010

But when I try to use Paperclip's before_post_process:

before_post_process :get_file_info
def get_file_info
  puts File.new(self.media.to_file.path).mtime  # =>Wed Apr 14 18:36:22 +0200 2010
end

I get the current date instead of the capture date. How can I fix this? Also, how can I get the video duration and store it with the model?

Thank you.
