Here's a link to the plugin and source:
http://www.flwoutdoors.com/GoogleTracker.zip
It's a 3.1.3 plugin, and should work with either regular or commercial flowplayer. Call the plugin like this:
plugins: { gatracker: { url: "/path/to/flowplayer.GoogleTracker.swf", google_id: "UA-xxxxxxx-x", debug: false} }
Where the google_id is your Google ID. If debug is true, the plugin won't send tracking info to Google but will instead draw what it would have sent over the video.
This tracks onStart (start(1)), Play, Pause, Stop, and Finish. Also replays (start(2)). It fires two events for each, just because of the way I needed to use it. You could pretty easily modify the source and recompile to do whatever you need it to. Just be sure to have the analytics.swc in your flexdir's /frameworks/libs directory when you compile.
This also works when compiled into flowplayer, so you can compile all of the options right into the flowplayer.swf file for embedding, which was the original problem on this thread.
If the embed code includes the parameter "AllowScriptAccess=always" then this movie will also report what website and page it's embedded into. Note that this site tracking won't work for Myspace, which changes the AllowScriptAccess to "never" when you embed it. Oh well, can't win 'em all.
Hope it's useful for you.
