The New And Improved Clockwork PC Webcasting Script

WARNING: THIS IS A VERY GEEKY POST! READ AT YOUR OWN PERIL!!!

#!/bin/bash

### The Clockwork PC Webcasting Script###

# This script is the fruit of many hours of research into FFMPEG.

# You will need ffmpeg with x11grab, and a number of libraries that should be installed automatically.

# You will need a custom directory ~/Videos/Screencasts, otherwise change the output directory in the commands.

# You will also need to download and install the newest xcowsay from its homepage,

# because the older xcowsay from the Ubuntu repositories (2010-08-31 at the time of writing) will not work with the --monitor option.

# The chained command creates THREE separate files:

# x11grab for your desktop,

# video4linux2 for your webcam,

# alsa for your microphone or headset.

# This is very important to me because I use Openshot Video Editor, which cannot split audio and video yet, but can combine them very well.

# If this is not important to you, there are many fine commands that combine audio and video streams into a single file, so you don't have to use mine.

# However, this chained command will record everything synchronously, including webcam and audio.

# Enjoy!
