Attach, embed & view .flv video files

[Farstate]

Is anyone able to recommend a way to attach an flv file to a post and view it in-line? I know I could use custom BB code so have something like [flv]http://www.myserver.com/myfile.flv[/flv] and then that is translated into the embedded code, but ideally I would like something a little more straightforward for the user - i.e. they can just attach a file like they would a pdf or jpg.
