Getting duration of audio file C#

Question

Hi All,

I'm trying to get the duration for an audio file in c#. I got the following code to work on my local machine but when I deploy it to a windows server 2008 box it always returns a duration of 0 for .avi and .wav files.

WindowsMediaPlayerClass wmp = new WindowsMediaPlayerClass();
    IWMPMedia mediaInfo = wmp.newMedia(filePath);
    return mediaInfo.durationString

I have windows media player 11 installed on the server.

Any help would be most appreciated

Answer 1

I don't have experience with "WindowsMediaPlayerClass", but I have used TagLibSharp extensively, which is what I try to use for such things - it supports a pretty broad set of formats and that makes it's API much more usable that the built-in support in .NET

Quite possibly simply using TagLibSharp will solve your problems.

(Note that taglibsharp is maintained by the banshee project, but is hosted @ novell for apparently historical reasons. I don't know about the details, but that can make contacting the devs a little confusing)

Answer 2

My guess is that the media player isn't installed (it's not by default on server SKUs).

Did you try installing the desktop experience package?
