Ok, that definitely makes for a very good reason why the hi-res variant is
out. Doesn't make sense for the low res though... I'd think, especially
considering the desire to use SUSE on the corporate desktop, that this would
be supported.
I have previously compiled the module and added support, which worked very
well for my cams. The other reason this comes to mind recently is that I'll
be experimenting with the use of Polycom's PVX [1] software running via wine,
and connecting through to a codec at my office - I'm trying to guage
videoconferencing capabilities existing within Linux now. A discussion I had
with one of the techs (a VERY good one at that) over at Polycom told me that
the PVX software is the best bet for H.323 on Linux, far exceeding
Gnomemeeting in qualty. Understandably, since Polycom is most definitely in
the business of VTC. Through my job, I have a license available to me for PVX
and plan on testing out these capabilities, but I worry that using wine may
slow down the app a bit too much, and cause too many dropped frames.
Now, being the zealot and supporter that I am, I would love to be able to
recommend Linux as an alternative for desktop collaboration, but this is one
of the more crucial elements. Over time, perhaps messaging networks may come
to the capabilities that are really required, but on a smaller level, I
believe Skype to be the only viable option (though no video support in Linux
yet - I'm a bit disappointed by that).
Anyways, thats another place where my curiosity stems from. Thanks for the
quick response Carl-Daniel :)
