How to track flash / video content usage?

Question

I have a few YT videos embedded on the pages of my site. Is there any way (say, via Javascript/DOM) I can track the following:

1. How much % (bytes, duration, etc) of the video content got transferred to the user's browser? (The red progress bar in YT videos, for example.)

2. How much % (bytes, duration, etc) actually got played (watched by the user) in the user's browser?

3. Play/Pause/Stop/Rewind/FF patterns of the user... like, eg, the user watched the segment time1 to time2 M times, followed by time3 to time4 N times, and so forth?

Do the Flash players (esp, the browser plugin versions) provide any way to tap such user actions on the player as the Start, Stop, Pause, Rewind, jump to arbitrary point?

Answer 1

Everything you can do with JS is explained here: YouTube JavaScript Player API

The long and short of it is that you can get most information about what the user has done (play, pause, etc) but you can't really get much about the amount of data they loaded but didn't view.
