meta data does not contain time even if it does.

[spruce]

Hey somehow i dont get it to work properly. My ffmpeg was an installation for airVideo, so maybe that's the problem? Can you look over it and maybe say what i'm doing wrong?

Thanks for your great engagement to do a cool wrapper.

Spruce: Can you fill on some details on how you fixed this? Running into the same error.

Sure :) My Problem was, that the filmname contained spaces, which were not correctly handed over to ffmpeg. So I kind of hacked the enclosing part of the lib. Because I wanted to develop this great library a little further I created a fork of it: https://github.com/spruce/node-liquid-ffmpeg
