AVI file length in time

[Guest]

How can I, preferably using C#, find out the length, in time, for an AVI file?

Joachim,

There is no easy way to do this. The best way would be to interop with
the DirectShow components (it would require COM interop) and get the
information from there. You can load the file in a graph in DirectShow, and
it should give you information about the length of the file, etc, etc.

Hope this helps.

It's a *little* easier (but not much...you still need to interop with
DirectShow). You can use the MediaDet object to obtain information about a
media file without having to do all the graph building stuff yourself:
