Hi all, I am a newbie to AV. I am now trying to make instant replay available for the sports training (seems too dumb if I stop the recording and playback).

I have a camera which can export live hdmi feed, so that my computer can receive the live feed through certain devices. Now, questions are:

1. How can I replay and loop the video which happened few seconds ago?
2. How can I stop the looping and go back to live feed?
3. Seems VLC can be customized, will you guys suggest to use this or any better choices in this case?

Many Thanks,
