Re: [GnomeMeeting-devel-list] Speed/quality : part 2



Don't forget to report.

It is important I get the criticisms from people on this list, instead
from the users :)

The purpose is now to determine if the H.261 quality is now worse than
what it was yesterday or not. I personally don't see a big difference.

My advice is that :
- H.261 with the new changes is not worse (don't forget to run the
configuration assistant)
- H.263 is far better than yesterday
