Not really. It has been around for several years now. The Digium  
developer team has choosen to take another path and work on one  
solution that works both for audio, video, text and fax. However, I  
haven't seen that work begin anywhere. I can't honestly say if it's  
happening or not - you have to ask them. As usual with Open Source -  
it depends on what customers wants and pay developers for. While this  
branch solves a lot of issues for video, it is not the generic  
solution that solves it all. I wonder if that will ever happen,  
though... ;-)

I would like to get that branch up to date and get useful again, but  
have no customers that has interest in it. I think it solves a lot of  
issues and I have tested it with many different video terminals. The  
majority of the work was done by Aupix in the U.K. and I believe they  
have continued from there. I've maintained it meanwhile, since I know  
a lot of users use it.

If you have any patches to this branch, I'll be happy to merge it.

Regards,
/Olle
