   Video Processing Libraries?
  I'd like to know if there are any libraries out there that can determine the width and height of most video file formats using C++.  I'm going to be using it to resize dynamically uploaded content on the web since &#106avascript (I've tried it already and asked around on 2 different forums for the &#106avascript) isn't enough to deterimine the width or height of a video file.Thanks a whole bunch!   
  DirectShow can do what you want (see IBasicVideo::GetVideoSize). However, to load things other than AVI, MPG, ASF, WMV, and DVD, like MOV files for instance, you will need to find DShow filters for them.   ;  Thank you so very much.  That was the exact information that I was looking for.  Is that library in addition to jpeg and gif's by any chance?  I also need a library that reads the header files and gets the width and heights of them as well.
