# Quick video capture with dmenu
#
# dependencies:
# - ffmpeg
# - hacksaw: part
# - xdotool: active,window
# - xdg-user-dir
# - dmenu
# - clipp
#
# Usage:
# vrec [command] [dir]
# - if you do not provide a command it will launch dmenu.
# - if you provide command and dir it will save the recording in dir
# Commands:
# - active: capture the active window
# - part: select a part of the screen to record
# - stop: stop an active recording
# - full: record your full screen
# - last: copy the latest recording's path to the clipboard
# - audio: one of the prior recording commands but with sound
# - window: select a window with xdotool and capture that geometry
# Recording:
# there is a lock file
# $1: x
# $2: y
# $3: width
# $4: height
# $5: output dir
# $6: output name
