Hi,

Of course, you can extract the first frame form a video. But I think it will be a little complex due to different video types. You can use IMediaDet interface to extract frames from video files.

# IMediaDet Interface

Here is a sample using this interface.

Hope this helps.

I literally just integrated something like this in my project.  The video, however, needs to be converted into FLV and you need to have FFMPEG in your application directory.  You will basically run a command line executable from your web app.  Here's the article I read to set me up:

This guy made a wrapper class in C# that can be called from code-behind.  I had to modify it a little for my purposes, but it works.

Anyone else.. i was looking for something to use within C#.. some of the links show applications where someone would install and manually do this.

My link IS C#.  It relies on an executable that resides in your application directory (not installed), and uses the System.Diagnostics.Process namespace to execute ffmpeg.
