Screen Record

This script record the screen with the wf-recorder tool, it can be the hole screen or a specific area of it. The script is going to store the video in /tmp/screencast.mp4, this script only store one video, personally I think that have more than one record is a mess, more if you only wants to share a quick screencast to telegram, irc, cinny or even to share it through 0x0.st.
