I tried video calling on PR 1.2 using Skype. I was able to get it to work using N900 and the latest Skype binary for Windows. It did not work with the previous Skype binary for Windows (which is acceptable), but it also didn't work with either MacOS or Linux. I tried initiating the call from MacOS and Linux and from the N900 and it didn't work in either case. It would say that video was starting, but it never would and the call would just proceed as an audio call. MacOS <-> Linux and {MacOS,Linux} <-> Windows video calls worked fine, so it wasn't a problem with the configuration on the MacOS or Linux side.
