Which application do you advise for video chat?
This is one of the most frequently asked question and one of the most annoying question for a UNIX guy like myself to answer. The reason is following. OP asks the question about video chat application even though she/he is really asking for a proprietary Skype client. Namely for better of worse lousy Skype protocol has won the video/audio chat wars just like lousy VHS won similar battle in 1980s. The protocol is proprietary, closed source, and only the proprietary vendor can release the FreeBSD client for it. Proprietary vendor, in this case NSA pardon Microsoft, does that not out of goodness if its heart but because of the financial benefit or in this case so that the big brother can listen to your conversation.
Now lets for a second pretend that OP asked really about video/audio chat client. I come here and tell you that
pjsua which is not ported to FreeBSD but works like a charm on OpenBSD is the best SIP video/audio client. No nonsense CLI, open source SIP protocol which is used as a building block for many top notch proprietary vidoe/audio clients were privacy is of concern. How will that benefit OP anyhow? Namely OP wants to talk to somebody. With probability 1 the other party is technically clueless and have heard only about Skype (maybe WebEx if it is a U.S. based business partner). How will the fact that pjsua is the best of the best (this is now direct link to the project)

benefit OP? It will not in any shape or form. FreeBSD or for that matter any BSDs are not commonly used as a desktop OS and not fully polished end products (Surprisingly Open is probably the most usable as Desktop OS). As such they are not target platform for any proprietary vendor which a scientific computing guy like me makes really sad (how wonderful would be to be able to use MATLAB on FreeBSD or GPU cards and ditch Red Hat). There is nothing that BSDs can do different to change this situation. So pull that smart phone of yours and just make a damn Skype call.
For the end of this long boring post I will tell you little story from this year BSDCan held in Ottawa. For some reason I got to share a room with one of OpenBSD alpha-males developers. First night I wanted to check on my kids who were at grandma's place in Cleveland U.S. and he wanted to do that with his kids in Germany. I pulled my Android phone and my Skype video call over WiFi well aware that every word will be recorded by NSA. He did the same with his kids in Germany fully aware of the lack of privacy. Did we feel bad about it? Not for a second. We have nothing to hide. We are just two fathers who were missing our kids. We used technically the easiest solution to accomplish the task. That evening we had a diner with bunch of other OpenBSD guys and they did the same while we discussed
tor network and how to game the guys from the office next to mine who have 15 million grant from one of three letter agencies to hack into
tor network.
