Hi,

I've been doing this 4 lectures per week for 3 weeks now.
Attached is a shell script I execute at the start of each lecture.
Its complicated by the fact that:
=A0 - it chooses file names based on date and time
=A0 - it puts them in directories specific to course,
=A0 =A0 also based on date and time
=A0 - it launches something to try to check that the
=A0 =A0 recording is working, as I've had trouble with that
=A0 =A0 and I sometimes forget to check at the start of the
=A0 =A0 lecture. =A0But basically, it does something like the following:

=A0 =A0 =A0f=3D`date +"%F-%T"`
=A0 =A0 =A0p=3D/files/local/src/Python/pyvnc2swf-0.9.3/pyvnc2swf/vnc2swf.py
=A0 =A0 =A0rec=3D"rec -c1 -r11025 -u -1 -q $f.wav vol 5 db"

=A0 =A0 =A0function dorec() {
=A0 =A0 =A0 =A0 =A0x11vnc -viewonly -wait 100 -defer 100 &
=A0 =A0 =A0 =A0 =A0sleep 3
=A0 =A0 =A0 =A0 =A0lecture-check-recording $f.swf $f.wav &
=A0 =A0 =A0 =A0 python $p -n -o $f.swf -r 4 -S "$rec" =A0localhost:0
=A0 =A0 =A0}

=A0 =A0 =A0dorec


=A0 =A0- then, later, a script does:

=A0 =A0 lame --resample 11.025 $src.wav $src.mp3
=A0 =A0 p=3D/files/local/src/Python/pyvnc2swf-0.9.3/pyvnc2swf/edit.py=20
=A0 =A0 python $p -o $dst.swf -a $src.mp3 -c -K 500 $src.swf

=A0 =A0 where src and dst are determined by the script ...

=A0 =A0 Of course, if you don't use Linux, none of this will make any sense.
=A0 =A0 Sorry about that.
