'''screen-mouse-image notes:'''
- The registration point is (at least by defualt) at the top left corner of image.
- File location is relative to your VLC installation folder

Run...
% '''vlc -H'''
...for the definitive options for your version.

== Example ==
Capture a screen:
% '''vlc screen:// --screen-fps=1 --screen-width=100 --screen-height=100'''
The screen thus captured is 100x100 pixels in from the top left corner of the active screen.

Show mouse on screen:
% '''vlc screen:// --screen-fps=30 :screen-mouse-image=file:///c:/cursorimage.png'''

===Questions ===

How to save?
Where is the file saved?

Example of a file save (:file{dst=D:\\savedir.mp4}):
% '''vlc screen:// :sout=#transcode{vcodec=h264,vb=0,scale=0,acodec=mpga,ab=128,channels=2,samplerate=44100}:file{dst=D:\\savedir.mp4} :sout-keep :screen-mouse-image=file:///c:/cursorimage.png'''

How to get audio to work?

On a dual head monitor, how to make sure the recording is happening on target monitor?

=== Commands I've used ===
vlc screen:// --dshow-fps=29.950001 --nooverlay --sout #transcode{vcodec=h264,vb=800, scale=0.5,acodec=mp3,ab=128,channels=2} :duplicate{dst=std{access=file, mux=mp4,dst=/home/user/Desktop/test.flv}}

Produced a black screen... on my Fedora 12 machine.
