You can only record from the the point were you actually start
capturing, I know this looks like a pretty dumb answer ;)

I don't know any software that can guess when to start capturing, or
that can (while capturing) clean anything prior to that 10 min window.

timed capture is easy with guvcview :

guvcview --video=FILENAME --vid_time=1200 --exit_on_close

this will capture 20m = 1200s of video to FILENAME and exit.

For the behaviour you are asking for maybe you need to develop
something yourself,
or for the easy way just push that button 10m earlier ;-)

Best regards,
Paulo
