Hi Nathan,

Speaking as one of the people who worked on adding video support to  
appconference, the problem you encounter is not typical. Appconference  
does not mix video in any way, it just switches video streams  
according to various criteria.   My guess would be that your video  
streams don't have key frames at short enough intervals, so you're  
basically getting p-frames from the new stream, while your endpoint  
still thinks it is decoding the old stream.

Anyways, appconference is very much alive, even though there were no  
significant developments in the past 8 months or so. It is used in  
several production environments, one of which I use on a daily basis.

I would suggest that you forward any appconference-specific questions,  
concerns, etc to the appconference dev list at appconference-devel at lists.sourceforge.net 
. We're always interested in hearing about bad (and good) experiences  
with the software

Cheers,
Mihai
