I've searched about this for a while, and most answers seem to suggest using the directshow library, which I've tried, but it didn't work. My program currently works on selecting a video file using the FileOpenPicker, then checks its length and uploads it to the cloud if it's below a certain length. Please keep in mind that this needs to work for Universal Windows Apps.

  • You might want to tell us will file formats you're supporting. Getting length of a DVD is different than of an AVI file for example. – Complexity Aug 25 '15 at 09:58
  • I guess I'd like to support as many formats as possible down the road, but for now I'm using MP4 files only – Ibraheem Nofal Aug 25 '15 at 10:25

You can use DirectShow API MediaDet object, through DirectShow.NET wrapper library. See Getting length of video for code sample, get_StreamLength gets you the duration in seconds. This assumes Windows has MPEG-4 demultiplexer installed (requires third party components with Windows prior to 7, I believe the same applies to another answer by cezor, there are free to redistribute components though).You can use DirectShow API MediaDet object, through DirectShow.NET wrapper library.

  • I did try the method provided in the first link of your answer prior to posting this question, but it didn't work. It threw an exception and gave me a "class not registered" error. That's why I was hoping to find a solution that'd work when developing for windows universal apps – Ibraheem Nofal Aug 25 '15 at 11:32
