This is great info!
Just a couple notes... this is not part of the FireAnt desktop
application, but just a small little web app I'm making. I don't have
Flash Media Server (seems expensive for a small little side project
like this).
Re: FLV support in FireAnt, this is definitely something we wish to
improve. The Mac version of FireAnt supports FLV playback, but it
could be done in a much better way (we have this duration issue with
FireAnt on the Mac too). On Windows, FireAnt plays Flash through the
Flash OCX, but it does not yet handle FLV. This is something we plan
to address soon. I've done some research here and think I have a good
starting point for that problem on the C++ side. Perhaps we should
also join the Adobe Developers Network.
Thanks!

You cannot get or even estimate the duration from the NetStream properties that are exposed, other than by playing it to completion.

If your app is a desktop app, then write your own very simple parser that would figure out the duration of a FLV file and build it into your app. Since FLV is an open format (see http://www.adobe.com/licensing/developer/), this should be simple and quick. In fact I know it's both since a guy at VitalStream wrote exactly this to figure out the duration of user-uploaded files (they have the same problem of missing metatdata from older encoders) and it only took him a morning to create. I doubt they would release that code, since its company specific, but if you approached your Fireant C++ guru, he may have as quick an answer.
