Hi all,
So I took a couple hours last night/this morning to create a screen
cast of cheese and its usage. I think its pretty good.
http://herlo.fedorapeople.org/screencasts/cheese-final.ogg (9.4MB)
~4.75minutes
The only issue I saw with istanbul, was that when I'd sometimes launch
an application (cheese, or epiphany to show the cheese website) the
audio would get garbled a little or a lot during the presentation. I
am not sure if this is really a bug, or some sort of config error on
my part.
Very Cool & well done, though I thought you should raise your webcam to
look down on you some if possible. The audio processing is likely done
via shared memory/cpu on the motherboard, so when you launch other apps
it affects the encoding process (top). If there were dedicated
audio/video processing hardware or you ran istanbul with a lower 'nice'
priority and the other apps with a higher 'nice' value. This may not
work for I/O bound processes, but it's worth a try. You may have to
create some custom launcher scripts to limit any interference when
running larger apps like a browser. More on nice here -
http://www.linux.com/articles/58638 ...Also a light weight desktop like
XFce.org may help, when doing demos. If it's I/O bound, writing the
output.ogg to a different drive using a separate controller/channel may
help. - Cheers, Art
