any tools to analyze wmv file format?

Hello everyone,

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

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

I used mplayer before, and I think it could only play video. Could it analyze format, i.e. if a video cannot be played, what part (e.g. index part of wmv file) is wrong?

If yes, can you show me how (any docs)?

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

Thanks! I find it is a good codec. But does it contain analyze function (e.g. analyze what is wrong with a currupted video, like saying index part of wmv file is wrong)? I did not find such function, appreciate if you could let me know how to use ffmpeg to do such analysis functions?

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
