Omniture made media tracking easy with their creation of ActionSource.  You no longer have to make external javascript calls for when the video starts, pauses, plays, ends, etc.  The ActionSource object handles it all.  ActionSource is pretty easy to learn and implement but I do feel Omniture in general and the way they handle their reporting is quite ambiguous.  I'm lucky I just have to do the implementation and not the naming strategy for the tracking.  I am told what props, eVars, events, etc to implement and can easily fire them correctly because of ActionSource.

First you will have to setup your ActionScource object as usual.  Then you can track your videos by using the below function calls. 

When the video get initialized you need to call the media open function.

// mediaName :: Name of video
// mediaLength :: Duration of video
// mediaPlayName :: Name of video player
s.Media.open(mediaName, mediaLength, mediaPlayerName);

When the video play listener is called you need to call the media play function.

s.Media.play(mediaName, mediaOffset);

When a user pauses the video or it stops you need to call the media stop function.

s.Media.stop(mediaName, mediaOffset);

When the video is finished you need to call the media close function.

s.Media.close(mediaName);

The tracking call to Omniture doesn't get fired until the close() function gets called.
