.SH DESCRIPTION
.PP
        recordMyDesktop produces a file(default out.ogg) that contains a video and audio recording
.br
of a linux desktop session. The default behavior of recording is to mark areas that have changed(through libxdamage)
.br
and update the frame. This behavior can be changed (option 
.B
\-\-full\-shots
) to produce a more accurate result
.br
or capture windows that do not generate events on change(windows with 3d context or video display) 
.br
but this will notably increase the workload. In this case, enabling the 
.B
\-\-with\-shared
option is recommended
.br
(by default this option is disabled since copying small areas of display is faster 
.br
than uploading the whole image from video memory).
.br
.br
recordMyDesktop doesn't have a commandline interface.
.br
After startup, it can be controled only through the following signals:
.br
.br
.B
SIGUSR1
causes the program to pause if it's currently recording, and vice-versa.
.br
.B
SIGTERM
causes normal termination of the recording.
.br
.B
SIGINT
also causes normal termination.
.br
.B
SIGABRT
terminates the program and removes the specified output file.
.br
.br
.br
A typical scenario of recording can be a command as simple as:
.br
.B
~$ recordmydesktop
.br
which will produce a fullscreen recording named out.ogg
.br
while a command like:
.br
.B
~$ recordmydesktop foo.ogg
.br 
will write output to foo.ogg
.br
To specify a region for recording you can type this:
.br
.B
~$ recordmydesktop -x X_pos -y Y_pos -width WIDTH -height HEIGHT -o foo.ogg
.br
where X_pos and Y_pos specify the offset in pixels from the upper left
.br
corner of your screen and WIDTH and HEIGHT the size of the window to be recorded(again in pixels).
.br
If the area extends beyond your current resolution, you will be notified appropriately and nothing will happen.
.br
Notice also, that if any option is entered you have to specify the output file with the \-o switch.
.br
.br
.B
To normally end a recording you can press ctl-c.
.br
(which will send a
.B
SIGINT
to the program).
.br

.SH ENVIRONMENT

DISPLAY
.br
Display environment variable, specifying X server to connect to.
.br
.SH NOTES
.br
    Recording a window using the \-windowid option, doesn't track the window itself, but the region that it covers.
.br
Also when using that option the \-x,\-y,\-width and \-height options are relative to the specified window area.
.br
An easy way to find out the id of a window, is by using the 
.B
xwininfo
program.
.br
Running a command like :
.br
.B
xwininfo |grep "Window id:"|sed \-e "s/xwininfo\\:\\ Window id:\\ // ;s/\\ \.*//" 
.br
will give you only the id of the window(which should look like this: 0x4800005)
.br
More conviniently you can put all that in the command that launches recordMyDesktop like this:
.br
.B
~$recordmydesktop -windowid $(xwininfo |grep "Window id:"|sed \-e "s/xwininfo\\:\\ Window id:\\ // ;s/\\ \.*//" ) 
.br
.br
    Also, the lower quality you select on a video recording (
.B
-v_quality
option), the highest CPU-power that you will need.
.br
So it's always better to start with default values and manipulate the end\-result with another program.
.br
.br
.SH BUGS
Too resource intensive,outcome quality is not what it should be.
.br
(font colouring is somewhat fuzzy and occasionally borderlines remain unupdated when a window closes)
