Re: need a video function in wheezy

D'oh!  When replying to a post, I'm looking at the body of a message and 
tend to forget requirements stated solely in the subject line.


Have you searched through the releases of Wheezy to see if any have the 
specific version of the library you need?  If found, air-wall the 
machine, put in a new system drive, install that release, install the 
software, get it working, and never update.


Does anybody know if any hypervisors support real-time virtual machines?


Otherwise, it's a matter of finding the software maintainer and 
convincing them to bring the software up to date.
