any tools to analyze wmv file format?

Question

I am developing some application (similar to media player but performing more domain specific things) based on wmv file. I am wondering any existing free tools to analyze wmv format -- I am interested about general information about a specific wmv file (like frame rate, size, and do not need too defailed information). I need especially information like whether the wmv file is corrupted, and how wmv file is corrupted (e.g. index corruption). I need such tool to verify my application can report the same error. Any recommended tools?

I am developing with C# + .Net 3.5 + VSTS 2008 + Windows. But any tools based on Windows are appreciated.

thanks in advance, George

Answer 1

Yes, actually, mplayer is (open source, free) and does (will analyze and decode) all of those things.

And, it even plays the movie ... go figure

Answer 2

Have a look at http://ffmpeg.org/. Its sources can be compiled for Windows

Windows Media ASF Viewer 9 Series will give you a lot of details on the ASF (WMV) structure http://www.microsoft.com/windows/windowsmedia/forpros/format/ASFViewer.aspx
