Re: [GnomeMeeting-list] (no subject)

Hi,
 Test first that your driver works with xawtv.

  If it does not work with xawtv, 
         give up immediately as the driver is not v4l compatible.
                                   
 
 If it works with xawtv,
     *you know the driver implements SOME of the v4l specification.
     *the driver may work with gnomemeeting,
        (gnomemeeting uses different v4l calls to xawtv. for example,
         gnomemeeting requests a different screen size, and image format)
     
 If it works with xawtv, but not with gnomemeeting, try
   a)specifying a default/preferred format of rgb24
   b)a web search for gnomemeeting and the name of your camera.
      see what other people think of your camera with gnomemeeting.
   c)modifying pwlib/src/ptlib/unix/video4linux.cxx to contain hints
      specific to your camera. Send your changes to me/this mail list, 
      and I will add the code to the cvs.
   d)DONT blame gnomemeeting. 
       many video drivers are tested so that they work with xawtv, but not
         against the full v4l spec.
       the video grabber code in gnomemeeting was very carefully written 
          to follow the v4l spec.
       Nonone has found code in pwlib video handling that is wrong.
       
       Criticism of gnomeemeeting video, without carefull researh,
         is the quickest way to get me to ignore your comments.



Damien, this comment is almost suitable for the faq.
