ScreenRecorder&Microphone Audio Recorder Using FFMPEG & Python

CapCam.py

#!/usr/bin/env python3
'''

This Script Is Mainly From A Youtube User,
I Only Modified It Slightly To Make It Python3 Compatable,
And Added Custom Microphone Recording Support
Original Source Code: http://pastebin.com/BY1t5AcC
Thanks To Youtube User NoBeansJose

you can use $(xdpyinfo | grep dimensions | awk '{print $2}') instead of long one used
