Pause / Play video with button and log that action in xAPI output

How can I create buttons, or other interactions, that pause and play a video -- let's say a slide video -- and ensure that I can generate xAPI statements, such as:

User paused video at 32 seconds

User started video at 35 seconds

User exited video slide.

I can set interactions (buttons and click boxes) to be reported but am hoping I can get pause / play to work, as well.

Also, in which html or js file can I find xAPI code output by Captivate? I can't find it, but can clearly see the results in Scorm Cloud logs.

Thanks!
