Re: [Vnc2swf-users] How to record with audio, and why does it sometimes not work?

[Neal H. <nh...@do...>]

This is likely the wrong group for this, because I don't think its
a vnc2swf problem -- but just in case anyone has experienced
it:     

       At random times, the sound recorder fails to start.

I'm using a Fujitsu Lifebook Table, T-4220 (I think).
Gutsy Gopher Ubuntu (pre-Beta), with updates faithfully applied
every day.

4 lectures a week for 3 weeks, so far.  Almost always I have
the tablet PC on, in my office.  I shut the lid (so it goes into
suspend mode), go to lecture, plug in a bunch of stuff,
resume from suspend, and restart X (so it sees the projector
plugged into VGA; I think you are supposed to be able to do
this with xrandr, but haven't tried yet).

I run a shell script that basically does:

        p=/files/local/src/Python/pyvnc2swf-0.9.3/pyvnc2swf/vnc2swf.py
        rec="rec -c1 -r11025 -u -1 -q $f.wav vol 5 db"
        x11vnc -viewonly -wait 100 -defer 100 &
        python $p -n -o $f.swf -r 4 -S "$rec"  localhost:0

Every once in a while, I get this in the log file I keep:

    ...
    26/09/2007 13:05:34 Using raw encoding for client 127.0.0.1
    ALSA lib pcm_dsnoop.c:606:(snd_pcm_dsnoop_open) unable to open slave
    rec stio: Failed reading `default': cannot open audio device
    ...

And of course, no sound is recorded.
Yesterday, at the start of a lecture, it did this 4 times in succession,
and I even rebooted once in between.  I gave up, and they get
a slient movie (considering yesterdays lecture, that might be a blessing, ;-))

After lecture, suspend tablet, go back to my office, and it
works fine.  I can't seem to make it fail in my office when  I 
can do something about it.

Help!
