    ADFH - 2004-12-05

    Have quickcam:

    ID 046d:0840 Logitech, Inc. QuickCam Express

    Got qc-usb finally installed under 2.6.9 with latest CVS copy. Got xawtv to display picture of myself :) ..

    Go to record in xawtv to a file - get a cryptic message.. hrrmm.. ok.. UI a bit clunky.. doco light ont he recording side .. no probs.. let's try another program..

    Install debian 'vcr' package.. Tried it.. also didn't work. Anyone have a recommended package to record to a file?

    Also, when it comes to video conferencing - what packages to people use EXCLUDING gnomemeeting (which is a NAT nightmare thanks to H.323 and not much use due to death of netmeeting) ... anyone seen any reliable yahoo cam or msn cam ports?

    Anyway.. here's 'vcr' output:

    $ vcr --codec "FFMPEG DivX5" -a 'BitRate=220' --framerate 5 --source "Camera" --quality 50 --rectime 1m test.avi

      First, important suggestion: use
      "qcset compatible=dblbuf" if some application
      doesn't work. it might cure "vcr".
      About half of the programs require that.

      > Install debian 'vcr' package.
      Strange. I don't have that package in MY Debian
      (sarge).

      >Anyone have a recommended
      >package to record to a file?
      I would recommend "streamer": a command
      line program and simple but it works.
      Older versions (Debian Woody) do not correctly
      synchronize audio/video, though.

      >Also, when it comes to video conferencing - what >packages to people use EXCLUDING
      >gnomemeeting
      I've heard some people recommending "vic".

      Also take a look at file "APPLICATIONS",
      included in the qc-usb package.

      Ahh.. RE vcr package.. it might be from French guy whose unofficial repository I use...

      deb ftp://ftp.nerim.net/debian-marillat/ unstable main

      .. I have this in my /etc/apt/sources.list for various media format support not included in main debian respository..

      dblbuf didn't help VCR app..

      streamer works - but seems to not look as good as what I see in xawtv - brightness etc. seems diff..

      for a given set of lighting conditions, if I get it looking just right on screen, I get the impression I'm able to kinda capture those settings in a file and pass them back in - how does one do that?

        /proc/video/quickcam/video*
        files show the current settings,
        under the "Picture settings set by user"
        part.

        You can give these values to -c/-b etc.

      In the end I've ended up figuring out what works best in my lighting conditions..

      qcset compatible=dblbuf quality=best settle=1 adaptive=0 keepsettings=1 -c 16000 -b 50000

      ... however things still look a bit dodgy when played back from a motion jpeg in terms of contrast etc.

      Guess I'll keep fiddling
