Server based Extension for Chromium OS

Senario A visitor comes to our website and browsers clicks etc the session is tracked and an output file is produced with all the mouse positions, clicks scrolls and URL's visited along with time stamps. I want to play this back like a movie on the Chromium OS server and record the output to a MP4 File . The server needs to Open the text file containing the users actions Render a browser Open the URL from the log file Show a Mouse pointer moving around the page and clicking etc And whilst it is playing back the logged clicks and moves record an MP4 file. The server needs to be able to handle multiple sessions and record several MP4 files simultaneously You do not have to use Chromium OS Extension if ,you have another method of achieving the same result I am willing to try that.
