"Indeed, and OpenH323 has support for H.263 through FFMPEG."
I'm a little confused. One of the main videoconf client I make calls to
are DLink DVC-1000.
They only support H.263 for video's (not H.261 or H.264)
Yet everytime I call them I am unable to see their video, nor they are
able to see my video because they're using H.263 and GnomeMeeting (via
OpenH323 doesn't have H.263 - as far as I can see from OpenH323's page
is that they only do H.261 and no higher for video?
If OpenH323 can encode H.263 then how can I setup GnomeMeeting so taht I
can send H.263 video's? This is the bare minimum I need.
Thanks

Hi,
Well, ffmpeg is LGPL which means that you can link it as a library. Check out
ther legal pages http://ffmpeg.sourceforge.net/legal.php
Indeed, and OpenH323 has support for H.263 through FFMPEG.
Having compiled ffmpeg a while ago, I remember, that there is a "GPL" compile
option which means, that it disables all codecs which are non LGPL compatiple.
I wonder what's the case with H.263 (which would be a quantum leap to have it-
though it's not 264)
I also wonder how the Wengo guys and java sip-communicator folks solved their
legal problems concerning 263. (these are open source projects as well - some
GPL)
I wonder. In Europe, you are relatively safe. The best would be to have
support for video plugins, which means european could use the plugin and
americans would have to pay for it, or not use it at all.
Another idea, which would solve point 1 and 3 but not 2 above: use Theora.
Check this out: http://www.tipic.com/tipicim - it's an open source Video
Jabber messenger using Theora as video codec. Perhaps opal/Gnomemeeting could
benefit. This would do to video what Speex did for audio - a decent free
codec.
